Hardware Tips and Specifications

While there is not a great deal of factory-released original manual IS215SECAH1A information available online, there is not a great deal of original manual information about the printed circuit board, but some useful material suggests that its status as a solar MACC-BPPB-WEMD component is a strong starting point. Additional information on the series and individual product status of the IS215SECAH1A boards can be obtained by careful visual inspection with a supplementary breakdown of the individualised IS215SECAH1A product numbers. For the uninitiated, two of the more obvious hardware components integrated into the IS215SECAH1A PCB substrate can be recognised in the standard issue Ethernet ports, which are placed longitudinally across each other on the large printed circuit board. Although the IS215SECAH1A board itself contains no other Ethernet ports, the centre of the BPPB board to which it is attached has two identical Ethernet ports. The drive manager has access to eight other ports that connect to this IS215SECAH1A board. These ports are all female and are attached to the edges of the IS215SECAH1A board during factory installation by using screw brackets to improve connection efficiency.

In addition to the various female ports available to users of the IS215SECAH1A board, a series of integrated circuits are integrated into the design of this SECA module. Each of them should be labelled with an individual reference mark, and some of them appear to carry their own factory-applied reference labels with individual component specifications. The final obvious standout hardware feature for the IS215SECAH1A’s circuit board assembly is its series of factory drilled holes. These factory-drilled holes, which are used for mounting purposes, are insulated for complete surface and internal voltage protection, and they are present on the IS215SECAH1A board in a total of five.

Hardware Tips and Specifications

Analogue I/O Pack IS420YAICS1B is part of the Mark VIe series manufactured by General Electric.

This I/O pack allows connection between up to two Ethernet and one terminated analogue I/O board.

The kit can handle up to 10 analogue inputs, two of which can be configured as ±1 mA or 4-20 mA current inputs, and the remaining eight as ±5 V or ±10 V inputs, or 4-20 mA current loop inputs.

The kit can send and receive data over dual RJ45 Ethernet connectors.

For convenience, this IS420YAICS1B I/O package consists of two components; a general processor board and a data acquisition board, as described in the IS420YAICS1B instruction manual that accompanies our manual tab above.

The diagnostic fault detection process for this IS420YAICS1B product is handled entirely through its data acquisition board.

The relevant terminal boards employed in the ruggedly supported modular components of the YAIC analogue I/O kit are the TBAISIC and STAIS2A terminal boards, which are also considered components of the larger Mark VIe turbine control system family.

This IS420YAICS1B device is not actually an original development for its specific Mark VIe Turbine Control System family of features;.

This must be regarded as an IS420YAICS1 parent analogue I/O package, and notably it does not take advantage of the uniquely important Class B functional product revisions of this IS420YAICS1B product.

Whilst various units in the Mark VIe range can be used in dual, TMR or simplex redundancy applications, the IS420YAICS1B I/O package can only be used in TMR or simplex applications.

Note, however, that when using this package in a TMR redundancy application, three I/O packages will be used, whereas only one I/O package will be used in a simplex redundancy application.

Another important caveat is that all I/O packs in the TMR set must be in the same hardware form.

This DS200SIOBH1ABA General Electric printed circuit board was originally manufactured for General Electric’s Mark V series.

The Mark V series offered by General Electric has specific applications in the management and control systems of gas, steam and wind turbines and is known as the Mark V Turbine Control System Series.

The Mark V series, to which this DS200SIOBH1ABA printed circuit board belongs, is considered to be General Electric’s legacy series.

as it has been discontinued in the years since its original production. Although it is a legacy series of General Electric.

The Mark V series, to which the DS200SIOBH1ABA PCB belongs, is one of the most recently developed product lines, utilising GE’s patented Speedtronic technology.

This technology was first introduced in the late 1960’s with the introduction of the Mark I. This DS200SIOBH1ABA PCB is one of the most recently developed product lines. This DS200SIOBH1ABA printed circuit board, or PCB for short, is better known by its official functional product description.

This DS200SIOBH1ABA printed circuit board, or PCB for short, is better defined as a SC2000 VME I/O board by its official functional product description, as shown in the original General Electric and Mark V series instruction manual documentation.

Given this, this DS200SIOBH1ABA printed circuit board is not the original SC2000 VME I/O board that existed in the Mark V turbine control system family; it would be missing this DS200SIOBH1ABA printed circuit board.

This would be missing the extensive revision history of this DS200SIOBH1 parent product DS200SIOBH1ABA PCB.

This IS215VCMIH2C is designed as a VME communication card in the GE Mark VI turbine control system and is critical to the proper function of the entire system.

The VCMI VME communication board allows the input/output (I/O) card to communicate with other I/O cards mounted on the VME backplane, I/O mounted in the expansion rack,

I/O backup protection modules, triple-redundant control modules, and the main processor module or main processor modules.

The IS215VCMIH2C card is also broadly referred to as the VMEbus master controller. This PCB connects the communication between the I/O boards and the controller.

It also acts as the communication interface to the system control network (IONet).

The IS215VCMIH2C has four built-in port connections placed on its front panel.

These include an RS-232C serial port, D-plug connector, and three IONet 10Base2 Ethernet ports.

Each IONet connector is associated with three LEDs labelled TX/RX/CD.

The board has additional LEDs labelled Status, Fail, Run and 1. 2. 4 and 8.

The former is located above the reset switch (button) and the latter is located directly below the serial port.

Each control module in a Mark VI system typically contains an IS215VCMIH2C, these unique VCMI cards are used to execute data through the control system’s application software in communication with the main processor module.

Due to the critical nature of the VCMI modules, it is recommended that additional spares are kept on the shelf to avoid machine downtime situations.

The voltage feedback scaling board DS200NATOG2A is used in conjunction with two other boards in the LS2100 series, a gate assignment status board and a VME backplane board.

This model has five string outputs connected to a single 20-pin ribbon connector.

The DS200NATOG2A NATO board is a voltage feedback scaling board manufactured by General Electric.

This model is part of the second set of variants. The purpose of this model is to attenuate the AC and DC voltages on the SCR bridge.

When the DS200NATOG2A model performs these functions, it will ensure accurate derivation of bridge voltage feedback.

As mentioned above, the DS200NATOG2A model is a G2 unit that will replace the two bottom resistors with two jumpers, giving the model four resistors per string.

The output of the board is via five strings connected to a 20-pin ribbon connector.

In addition, there are several MOVs (metal oxide varistors) that prevent the output voltage from being too high if the ribbon circuit is interrupted while the input voltage is present.

The load resistors required for operation are located on the connected gate distribution status board, not on the NATO board.

VOLTAGE FEEDBACK SENSING BOARD TYPE DS200NATOG2A The attenuator voltage is set by a stinger connector and jumper for the G2 variant of the NATO.

There are several VLG and VLL inputs, one VLL input is 2200. the VLG input is 1270.17. and the VLG output for these inputs is 1.905.

For these particular inputs, there are several wire jumpers, two resistors, and an input stab connector JxA.

The DS200NATOG2A model uses multiple agency approvals; these certifications are CSA, EC and UL standards for controlled and known transients.

The IS220PDIOH1A is a discrete input/output module manufactured and designed by General Electric as part of the Mark VIe series used in distributed control systems. The electrical link between one or two I/O Ethernet networks and the discrete input/output terminal block is provided by the Discrete Input/Output (PDIO) package. The kit includes a capture board dedicated to discrete input/output functions and a processor board shared by all Mark VIe distributed I/O packages. The pack can accept up to 24 contact inputs, manage up to 12 relay outputs, and obtain terminal board-specific feedback signals.

Functional Description

The voltage capability of the PDIO is determined by the connected terminal board. The three-pin power input and the two RJ45 Ethernet connectors are used as system inputs to the battery pack. the DC-62 connector connects directly to the corresponding terminal board connector for discrete signal inputs and outputs. the LEDs are used to display visual diagnostic information.

Functionally, the PDIO is equivalent to combining the PDIA and PDOA I/O packages into a single unit. It is mounted on the TDBS terminal block for simplex applications, which is a hybrid of the SRLY relay terminal block and the STCI contact input terminal block.

It is mounted on the TDBT terminal block used for TMR applications, and when used in conjunction with the WROB option, provides the ability to combine the terminal block with a TBCI contact input terminal block. The following diagram shows the connections established when three PDIO packages are installed on a TDBT terminal board.

Specification

Part Number: DS200PTBAG1A

Manufacturer: General Electric

Series: Mark V LM

Product Type: Terminal Block

Availability: In stock

Country of Manufacture: USA

Manual: GEH-6153

Functional Description

The DS200PTBAG1A is a protective core terminal block manufactured by General Electric as part of the Mark V series used in gas turbine control systems.

The signals from the core are terminated by a Protective Terminal Block (PTBA) located in the core. Connected to the PTBA terminal block on the TCEB board are input signals for high and low pressure shaft speed, flame detection, generator and bus voltages, and generator current.

The core is also connected to the speed signals. The Turbine Trip (TCTG) board in the core is written directly after the PTBA terminal board reads the external trip input signals, the generator and bus signals, and the generator breaker closing signal.

Through the PTBA terminal board, the TCTG board writes the trip output signals and generator circuit breaker closure signals to the device.

Using the hardware jumpers on the PTBA board, the TCEB board’s audio alarm (horn) is energised.
