Products Description
GE DS200TCRAG1ACC Relay Output Board in stock
GE DS200TCRAG1ACC is a relay output board for GE Mark V Speedtronic gas and steam turbine control system. It receives control logic commands from the main turbine controller and drives 30 plug-in relays to output dry contact signals for turbine trip, valve control and auxiliary equipment actuation.
This board is equipped with 30 replaceable plug-in relays, 4×34-pin and 4×12-pin multi-pin connectors. It provides electrical isolation between the control rack and field loads, with onboard LED indicators for relay channel status and fault diagnosis. It is an obsolete legacy PCB, mainly used as surplus or refurbished spare parts for power plant Mark V turbine control cabinet maintenance.
