Hardware Tips and Specifications

The required operation of the IXTD board is provided through the circuitry

of the connected power supply/interface board (IMCP).

When the IMCP and the IXTD board are connected, they are connected via a four-pin connector.

When the board is installed, it will be externally mounted and must

be sized to meet the worst-case switching requirements of dynamically braked IGBTs.

The purpose of the snubber board is to be used to limit voltage transients

​at both ends of the IGBT and at all known operating conditions of the driver.

Another function of the DS200ITXDG1ABA board is to regulate the output

of the IGBT gate driver board to match the electrical characteristics of the AT frame driver.

AT frame drivers are available in variable and constant torque applications.

The drive output current rating for variable torque applications is 500 ARMS.

The DS200ITXDG1ABA board has three connector types: bus I/O connectors,

input connectors for DBPL, and board pin connectors.

All of these connector types have different pin numbers, nomenclature,

and descriptions, which are explained in depth and in detail in the 

DS200ITXDG1ABA instruction manual included above for your convenience.

Bus I/O connectors and pin I/O connectors are also oriented. 

Two examples of pins associated with the stab I/O connectors are the

E-6 and E-9 connectors, both of which are output connectors.

The E-6 connector is the DB IGBT gate signal and the E-9 connector is the connection for the external buffer resistor.

About the DS200ITXDG1ABA

The DS200ITXDG1ABA board is labeled as a Dynamic Brake Buffer Board and

is part of the Mark V Series manufactured by General Electric.

The Mark V Series, of which this DS200ITXDG1ABA product is a part,

was one of the last of General Electric’s Mark product line to incorporate

Speedtronic control system technology into its various products.

And since it was eventually discontinued many years after its initial release, it exists as a legacy product line.

This DS200ITXDG1ABA Printed Circuit Board, or PCB for short, is not an original development for

its specific Mark V Turbine Control System family of functional roles;

it is actually the DS200ITXDG1 Parent Dynamic Brake Buffer Board.

The DS200ITXDG1ABA PCB is conspicuously missing all three versions

of the three important product versions of the DS200ITXDG1ABA PCB.

The assembly of this DS200ITXDG1ABA PCB has been specifically

altered to utilize a Level A Major Function Revision, a Level B Minor Function Revision, and a Level A Drawing Configuration Revision.

Product Overview

-The Reflective Memory concept provides a very fast and efficient way to share data between distributed computer systems.

VMIC’s VMIVME-5576 Reflective Memory interface allows data to be shared between up 

to 256 independent systems (nodes) at rates of up to 6.2 Mbyte/s. Each Reflective Memory board can be configured with up to 256 nodes.

Each Reflective Memory board can be configured with 256 Kbytes to 1 Mbyte of on-board SRAM.

local SRAM allows fast reads of stored data.

Write data is stored in the local SRAM and broadcast to other Reflective Memory nodes via a high-speed fiber optic data path.

Data transfers between nodes are software transparent, so there is no I/O overhead.

Transmit and receive FIFOs buffer data during peak data rates to optimize

CPU and bus performance and maintain high data throughput.

Reflective memory also allows interrupts to one or more nodes by writing to byte registers.

These interrupt (tertiary, user-definable) signals can be used to synchronize system processes or to follow any previous data.

Interrupts always follow the data to ensure that the data is received before the interrupt is acknowledged.

The VMIVME-5576 does not need to be initialized unless interrupts are used.

If interrupts are used, vectors and interrupt levels must be written to on-board registers and interrupts must be set.

Each node on the system has a unique identification number between 0 and 255.

The node number is determined by placing jumpers on the board during hardware system integration.

The node number can be read by software by accessing the on-board registers.

In some applications, the node number helps determine the function of the node.

About the IC694MDL930

This IC694MDL930 is part of the PACSystem RX3i midrange programmable automation controller (PAC) platform.

It is designed for use as a relay output module with eight (8) independently isolated normally open (N.O.) or A-type contact outputs.

Each output contact essentially has a separate common and dry contact, allowing different voltage types and levels to be connected exclusively to the module.

i.e. 5-30 VDC (nominal 24 VDC) and 5-250VAC (nominal 120/240VAC).

The current capacity of each output channel is 4 amps per output when used with resistive loads and 2 amps per output when used with pilot load devices.

Current capacity is 2 amps per output channel. For UL installations, the maximum load current that the module can withstand is 30 amps and varies according to ambient temperature.

Conversely, the minimum load that the module can withstand is 10 mA, and the module’s output channels have a typical response time of 15 ms between on and off switching, while the module’s maximum backplane current is 2 amps.

The module’s maximum backplane current draw is 6 mA, and all outputs are energized by a 5 VDC bus on the backplane.

All outputs are energized by a relay 70VDC bus on the backplane and the maximum backplane current consumption is 24mA.

The module also supports mounting to 90-30 series backplanes. It can be used as a local output module, mounted on a central processing unit (CPU) chassis, or with an appropriate communications adapter.

The 169PLUS-120N-125VDC is a highly configurable motor protection system manufactured by General Electric Multilin.

The relay comes with basic setpoints programmed for large motor systems, which can be further adjusted by the user upon receipt of the relay or as they become more familiar with the data generated by the relay.

While users can manage their motor systems with fairly minimal connection to GE Multilin’s 169PLUS-120N-125VDC.

However, the unit does offer a wide range of ports to diversify and customize the function of the relays.

Some of these connections include:

. Auxiliary Relay Contacts: these two contacts provide an additional NO/NC connection and operate independently of the other contacts.

The relays can be configured as non-fail-safe or fail-safe, and latching or non-latching.

They can be used for active alarm or trip functions and can trigger devices that are not just motors.

RTD Sensor Connections: The user can connect up to 6 resistance temperature detectors.

This is used to monitor values such as stator motor temperature, historical hottest temperature and ambient air temperature.

The relay then uses the data obtained from these connections to schedule the optimal cooling process.

. Analog output terminals: These two terminals can be configured using the relay’s setpoint system.

It can be connected to chart recorders, remote meters, programmable recorders and/or computer loads.

. Emergency Restart Terminal: This connection type overrides trips within the system and forces a restart of the motor.

These connections add to the overall versatility of the system and can further protect motor components from damage during operation.
