The IS200EPDMG1BAA belongs to GE’s EX2100 control system. It serves as the central power backbone for exciter applications. This module takes 125V dc from the station battery. Additionally, it supports one or two 120V ac inputs for backup scenarios. Power inputs pass through filtration via the onboard terminal block (TB1). Consequently, clean and stable power reaches downstream boards.
The IS200EPDMG1BAA measures 17.8 cm high by 33.02 cm wide. It uses surface mount technology. The module provides a 24-point terminal block and ten plug connectors. These connectors are rated at 600V ac or dc. Seven toggle switches offer individual power control. Each switch is rated 125V dc and 6A. Fourteen fuses protect each output circuit.
Eight green LED indicators line one long edge. They show power availability at a glance. An adjustable jumper (BJS) allows ground reference isolation. This feature proves useful when external references are present. The board includes metal oxide varistors, capacitors, and resistors for circuit protection.
External AC to DC converters (DACA) rectify ac inputs to 125V dc. The resulting dc voltages are P125V and R125V. Diode coupling maintains nominal values of +62.5V and -62.5V relative to ground. Connectors JDACA1 and JDACA2 enable easy connection of ac power sources to external DACA units.
Individual power outputs to exciter boards come with fuses and toggle switches. Green LEDs confirm each output is active. This design gives you convenient monitoring and control. The IS200EPDMG1BAA supports multiple exciter boards, including:
Exciter Gate Pulse Amplifier Boards (EGPA)
Exciter Terminal Board (EXTB)
Exciter Power Supply Modules (EPSM)
Safety remains a priority. The module is chassis and safety grounded through specific mounting holes. Four grounded mounting holes ensure stable installation. This robust grounding mitigates electrical risks. It also enhances overall system stability during operation.
Operating temperature: -30°C to +65°C
Storage temperature: -40°C to +85°C
Humidity: 5% to 95% non-condensing
Mounting: Panel mount via four corner holes
First, ensure the station battery supplies a stable 125V dc. Next, connect ac backup sources to JDACA1 and JDACA2 if needed. Then, mount the IS200EPDMG1BAA securely using all four grounded holes. After mounting, wire the terminal block TB1 for power inputs. Finally, set each toggle switch to the desired position. Use the green LEDs to verify power distribution.
For systems with external ground references, adjust the BJS jumper accordingly. This flexibility makes the module compatible with various system configurations.
Specifically, each output channel has independent fuse protection. Moreover, the toggle switches allow quick disconnection during maintenance. Meanwhile, the LED indicators provide real-time status feedback. Therefore, troubleshooting becomes straightforward. Additionally, the compact size fits standard panels easily.
The IS200EPDMG1BAA offers reliable power distribution for GE EX2100 systems. Its combination of fuses, switches, and LED indicators gives you control and visibility. Furthermore, the dual input option (dc plus ac backup) ensures operational continuity. Because of its robust grounding, electrical noise is minimized. Thus, sensitive exciter boards receive clean power.

1. What systems is the IS200EPDMG1BAA compatible with?
It works with GE’s EX2100 exciter control system. It also supports EGPA, EXTB, and EPSM boards.
2. Can I use only the 125V dc input without ac backup?
Yes. The module accepts dc alone. Ac inputs are optional for redundancy.
3. How do I know if the module is receiving power?
Look at the eight green LED indicators. They light up when power is present.
4. What should I do if a fuse blows?
Replace it with an identical rating fuse. Then check the connected load for shorts.
5. Is the IS200EPDMG1BAA grounded through its mounting holes?
Yes. Four mounting holes provide chassis and safety grounding connections.
