The IS200UPDCG1A is a Power Distribution / DC Module within the GE “IS200” / Mark VI / Speedtronic control system family. It functions to distribute DC power within a control rack or system (e.g. distributing 24 V DC to modules or I/O packs). It ensures stable, reliable delivery of DC power to the system’s internal modules under redundancy and fault conditions.
This board is typically used in turbine control systems, excitation controller racks, and industrial automation systems where controlled DC power rails are required across multiple modules.
It is engineered to meet industrial-grade reliability demands: proper isolation, diagnostic monitoring, fault protection, and seamless integration with GE control architectures.
Here is a table of known / plausible parameters for IS200UPDCG1A:

| Weight | ~ 0.40 kg |
| Isolation / Insulation | DC output isolation, board-level protections |
Typical application areas for IS200UPDCG1A include:
Distribution of DC power to internal modules in turbine control racks (Mark VI / Speedtronic)
Supplying internal I/O packs, CPU modules, communication modules with steady DC rail
Enabling redundancy in power rails—if one supply fails, distribution module ensures continuity
Retrofit or repair in legacy GE control systems that require DC module replacement
Use in industrial control and automation systems requiring organized DC bus power partition
Some key advantages of IS200UPDCG1A include:
Reliable DC Power Distribution: Ensures that internal modules receive stable DC supply without voltage drop or undue noise.
Fault Protection: Overcurrent / short circuit protection and fusing reduce damage to downstream modules.
Compact Integration: Designed to fit into the same rack or chassis as control modules, minimizing extra wiring.
Diagnostic Capability: LED indicators and fault detection help operators quickly isolate issues.
System Compatibility: Made to integrate into GE control architectures, so signals, connectors, formats align well.
Durability: Designed for industrial temperature ranges, robust board layout, insulation, and isolation to withstand harsh environments.
