OVERVIEW

All I/O modules are connected to the high-speed Bus Interface Module (BIM) via a proprietary bus system called “Railbus”.

Up to 32 modules can be connected to one BIM. The module backplane provides the transmission medium for the Railbus.

At the same time, the modules can be connected to the bus by plugging them into the base plate. The connectors on the base plate also provide the power supply for the modules and, if necessary, for the field wiring.

Addressing of I/O modules

Modules are addressed by the bus interface module according to their location or slot and by combinations of 32 modules rather than individual module types.

Modules can therefore be removed and replaced by another module of the same type without “informing” the Bus Interface Module.

During the configuration process, the Bus Interface Module is informed of the location characteristics of each required module, regardless of whether the module is present at the time.

Therefore, if a module is replaced, the attributes of that “slot” remain with the bus interface module.

Critical modes

Output fail-safe mode

The output module can enter a fail-safe state. The module will enter this state if either of the following two reasons occur.

(1) The BIM forces the module into a fail-safe state by issuing a special command.

(2) The module has a configurable “timeout” parameter. This allows you to specify a maximum amount of time that communication with the BIM will cease.

Once this time is exceeded, the module will go to a fail-safe state. Different types of modules respond to fail-safe commands in their own ways, which are described separately in the following sections.

It also provides three configurable input filtering times to compensate for noise spikes and switching jumps of 0.25 ms, 1.25 ms, and 7.25 ms. Two input groups have a common connection point.

One group can be wired for positive or negative logic. If the system requires additional bus terminals.

A shorting bar with 2 amps of current-carrying capability is also available for use with the B-terminal.

The IC200MDL643 discrete input module has an input voltage of 0 to 15 volts DC and a user input current of 1.8 milliamps at 5 volts DC and 4 milliamps at 12 volts DC.

The user input current is 1.8 mA at 5 volts DC and 4.9 mA at 12 volts DC. It has no thermal derating and no external power supply.

During installation, make sure that hot plugging and unplugging is done correctly to avoid backplane interruptions.

Operation:

The VSVO provides four channels including bi-directional servo current outputs, LVDT position feedback, LVDT excitation, and pulse rate flow inputs.The TSVO provides excitation for, and accepts inputs from, up to six LVDT valve position inputs. One, two, three, or four LVDTs can be selected for each servo control loop, and if three inputs are used, they can be used for gas turbine flow measurement applications. These signals are transmitted through the TSVO and sent directly to the front of the VSVO board at J5. Each servo output is equipped with a firmware-controlled, independent suicide relay that short-circuits the VSVO output signal to common in the event of a power failure and returns it to the nominal limit when a manual reset command is issued. Diagnostics monitor the output status of each servo voltage, current, and suicide relay.

Description:

General Electric’s IS200TSVOH1BAA circuit board assembly is part of the company’s Mark VI turbine control system. The Mark VI has been monitoring and controlling industrial turbine systems for decades. Meanwhile, Speedtronic systems have been in use since the late 1960s.

This IS200TSVOH1BAA is used as a servo valve termination board. While MKVI systems use many different termination boards, this particular board is a barrier type board that uses screws to clamp the wire connections. When connecting wires to the terminals, it is important to strip the wires to the correct length; otherwise, the screw clamps will be difficult to access.

This IS200TSVOH1BAA has two termination blocks located on one side of the board. Other connectors used on the board include d-shell connectors and vertical plugs. The board has six jumper switches that can be used to change the way a particular circuit works. Each jumper switch on the board has multiple settings. Before removing a jumper from the unit, be sure to make note of the way the jumpers were set on the previous board; best practice suggests duplicating these settings on the new assembly.

Other board components include relays, transformers, ICs, and transistors. For more information on these components and how the board should be located, wired, installed, and maintained, refer to the GE Speedtronic manual.

The IS200VSVOH1B is a VME servo control board manufactured by General Electric as part of the Mark VI series used in gas turbine control systems. The four electrohydraulic servo valves that operate the steam/fuel valves are under the direction of the servo control (VSVO) board. Typically, two servo terminal boards are used to separate these four channels (TSVO or DSVO). The valve position (LVDT) is determined using a linear variable differential transformer.

The VSVO performs a cyclic control algorithm. Three cables are connected to the VSVO at the J5 plug on the front panel and at the J3/J4 connectors on the VME rack. the JR1 connector is used for the

TSVO to provide simplex signals, while the JR1. JS1 and JT1 connectors are used to fan out TMR signals. The external trip of the protection module is inserted into JD1 or JD2.

IS200VSVOH1B Installation

Close the VME’s processor rack.

Place the board in place, then hand press the top and bottom ties into the base of the edge connector.

Tighten the plus screws at the top and bottom of the front panel.

The cable connections to the TSVO terminal board are made at the lower J3 and J4 connectors of the VME rack. They are locking the connections in order to secure the cables. Start the VME rack and check the diagnostic indicators on the front panel.

IS200VSVOH1B Operation

LVDT position feedback, LVDT excitation, bi-directional servo current outputs, and pulse rate flow inputs are contained within the four channels of the VSVO.

The TSVO can provide excitation for up to six LVDT valve position inputs, and the TSVO accepts inputs from them as well. For each servo control loop, one, two, three or four LVDTs can be selected.

For applications measuring gas turbine flow, three inputs are provided. These signals are routed through the TSVO and sent directly to J5 on the front of the VSVO board. when power is lost, each servo output has a dedicated suicide relay which, when controlled by firmware, short-circuits the VSVO output signals to common and then returns to normal operation after a manual reset command.

Each servo’s output voltage, current, and suicide relay are monitored through the diagnostic function.

GE IS200TVIBH2BBB The IS200TVIBH2B is a turbine control line module.

It is a high-performance, high-reliability module designed to meet the demanding requirements of turbine control applications.

The module is designed for use in a variety of applications including power generation, oil and gas, and petrochemicals.

The vibration termination board IS200TVIBH2B is one of the boards in the Mark VIe control system designed by General Electric.

This board is not compatible with any of the boards in the Mark VIe family, with the exception of the VVIB board. This board will have similar functionality to the TVBA board.

This board can be used not only in Mark VIe systems but also in Mark VI systems.

When the TVIB board is used in a Mark VI system, it can be supported in a TMR or Simplex system.

Up to two panels can be used to connect to the VVIB board. When this board is used in a TMR system, a single TVIB board will connect to three VVIB boards.

The IS200TVIBH2B board does not have any potentiometers and does not require any calibration.

On the face of the board, there are sixteen jumper switches that can be modified to suit the user’s needs. There are two barrier terminals for different types of vibration.

Functional Description:

The IS2020JPDBG01 is a power distribution board manufactured and designed by General Electric as part of the Mark VIe series used in GE distributed control systems.

The JPDB board for AC power distribution regulates, monitors, and decentralizes AC power. The module contains two line filters and an IS200JPDB board.

The module contains two independent AC power distribution circuits, each rated at 20 A at 115 or 230 V AC.

The input circuits should be wired in parallel to prevent PPDA alarms when only one AC power source is available.

Each circuit has one fuse output and three fuse and switch branch circuit outputs. the JPDF 125 V DC power distribution module has an optional connection.

The IS200JPDB has status feedback for all fuse circuits and passive supervisory circuits for both AC ranges.

On connector P1 is the supervisory circuitry for connecting cables to the board containing the power supply diagnostic PPDA I/O packages.

Port P2 on the IS200JPDB allows monitoring signals from other power distribution system cards to pass through.

Compatibility:

The JPDE, JPDF, JPDS, and JPDM feedback signal P1 and P2 connections on the IS2020JPDB are compatible, resulting in a PPDA I/O package. The AC input on the JPDF module of the same name can be used with connector JAF2.

Installation:

In the PDM cabinet, the IS2020JPDB module is mounted vertically on a metal rear base. The protective grounding system and the IS2020JPDB sheet metal must be connected.

For the first AC circuit, input power is delivered to terminals AC1H (line) and AC1N (neutral), and for the second AC circuit, input power is delivered to AC2H (line) and AC2N (neutral).

There must be a grounded neutral connection on both AC inputs. Follow the documentation for the system’s output circuit connections.

If the distribution system has a PPDA Power Diagnostics I/O package, a 50-pin ribbon cable is required to connect JPDB connection P1 to connector P2 on the board with the PPDA. Other core PDM boards can use the P2 connector for this connection.

About the DS200TCEAG1B

This DS200TCEAG1B printed circuit board or PCB for short was originally developed to exist as an Emergency Overspeed Board within the greater Mark V Turbine Control System Series. The Mark V Series is one of the more recent additions to the slew of Mark-named product series offered with General Electric Speedtronic technology, and specifically applies to wind, steam, or gas turbine control systems and automated drive assemblies. This DS200TCEAG1B printed circuit board is not the original Emergency Overspeed Board that was manufactured by General Electric for placement in their Mark V Turbine Control System Series; that would be the similarly-named DS200TCEAG1 printed circuit board notably missing this DS200TCEAG1B product offering’s singular B-rated functional product revision.

Hardware Tips and Specifications

This DS200TCEAG1B Emergency Overspeed Board has its own particular set of hardware component inclusions and specifications, as revealed in original Mark V Series instructional manual documentation. The General Electric Emergency Overspeed Board model DS200TCEAG1B features one microprocessor and multiple programmable read only memory (PROM) modules. It also contains 3 fuses, 30 jumpers, and a pair of bayonet connectors. The DS200TCEAG1B board monitors the Mark V Series drive for over speed and flame detection trip conditions and shuts down the drive as appropriate. The bayonet connectors in the assembly of this DS200TCEAG1B Emergency Overspeed Board are used to connect the board to other devices and boards in the drive; these male bayonet connectors on the end of the cables require some consideration before you connect them to the female connectors on the board, as detailed in depth in GE instructional manual materials. To remove a bayonet connector, hold the connector with one hand and with the other hand secure the board to keep it from bending or moving. Pull the bayonet connector out of the female connector on the board and put the cable aside until you are ready to connect it to the replacement board.

Several specific connectors and integrated circuits are incorporated into the assembly of this TCEA-abbreviated PCB. This DS200TCEAG1B Mark V Series printed circuit board’s circuits are tasked with various diagnostic functions relating to this DS200TCEAG1B PCB’s greater overspeed processing functionality. Some of these integrated circuits include the TCEA Flame Detection Circuits, the TCEA Turbine Overspeed Circuit, and the TCEA Automatic Synchronizing Circuit. Each of these circuits has been named in terms of their functionality to the greater DS200TCEAG1B printed circuit board and Mark V Series automated drive assembly.
