Description
🔹 Product Description
The GE General Electric DS200TCRAG1A is a TCRA Relay Output Board designed for the GE Mark V Speedtronic turbine control system. The board provides relay-based output interfacing between the Mark V control electronics and associated terminal boards and field devices. The DS200TCRAG1A uses up to 30 plug-in relays and includes four 34-pin connectors and four 12-pin connectors for control and relay-output interfaces. The related DS200TCRAG1ACC designation identifies a specific three-revision hardware configuration within the DS200TCRAG1A family. The board is used in legacy GE turbine control applications and is suitable for replacement and maintenance inventory.
