I/O modules

The GE IS200EPDMG1A IS200EPDMG1AAA distributes DC power to multiple control boards in Mark VI racks. This module accepts incoming bulk power and routes it to individual slots. Therefore, it replaces complex internal wiring with a simple plug-in solution.

Product Overview

We designed this distribution module for organized power delivery in turbine cabinets. Its circuit breaker protects each output channel against overload conditions. Moreover, this unit includes LED indicators for every power rail status.

Technical Specifications

Distribution Architecture

The GE IS200EPDMG1A IS200EPDMG1AAA routes input power through a heavy copper bus bar. Its circuit breakers mount directly on the bus bar for low resistance. Additionally, the module includes current monitoring on the main input. You get real-time power consumption data for the entire rack.

Energy Storage Note

This distribution module contains no capacitors or other storage components. All power passes directly from input to the protected outputs. Therefore, you can handle this module without any discharge delay. However, always disconnect the input power source before removal. The connected control boards may retain their own stored energy.

Circuit Breaker Features

Each output uses a thermal-magnetic circuit breaker rated at 5A. The thermal element responds to sustained overloads above 5A. The magnetic element trips instantly on short circuits above 30A. Breakers trip to the center position for clear fault indication. Reset a tripped breaker by pushing it fully off then back on.

Installation Steps

Insert this distribution module into the first slot of the Mark VI rack. Align the GE IS200EPDMG1A IS200EPDMG1AAA with both backplane connectors. Push the board evenly until both ejector levers lock into position. Then tighten all four corner screws for secure mounting. Connect the 125V DC input wires to the front terminal block.

LED Status Indication

A green LED above each breaker illuminates when that output has power. A red LED illuminates when the corresponding breaker has tripped. A yellow LED indicates the main input power is present. All LEDs remain visible with the rack door closed through a window. The module also sends breaker status through the backplane communication bus.

Current Monitoring

The main input passes through a Hall effect current sensor. This sensor reports current consumption to the system controller. The controller can generate alarms for excessive rack power draw. You can also view current trends through the operator interface. Historical data helps plan for future rack expansion.

Maintenance Procedures

Test each circuit breaker annually by manually tripping it. Push the red test button on each breaker to verify mechanism function. Reset the breaker after testing by pushing it to the off position. Then push it fully on to restore power to the output. Replace the GE IS200EPDMG1A IS200EPDMG1AAA if any breaker fails the test.

Application Scope

This distribution module suits Mark VI and Mark VIe turbine control racks. Many power plants use the GE IS200EPDMG1A IS200EPDMG1AAA for organized power delivery. Its modular design simplifies troubleshooting and reduces downtime.
