GE DS200RTBAG3AHC | Relay Terminal Board

Description

GE DS200RTBAG3AHC is a relay terminal board belonging to the GE Mark V series analog I/O board, designed specifically for gas turbine control systems. It has a CE certification, operates at a 220V working voltage, and supports an output frequency of 50/60 Hz. This board serves as a critical interface for signal conditioning and transmission, facilitating communication between various system components and the core control unit.

The board features a structured connector and bus system: power for the TCPS board is distributed via 2PL, while 3PL acts as a data bus connecting the STCA, TCQA, and TCQE boards in the core, with conditioned signals transmitted to the COREBUS through 3PL. Thermocouple inputs and cold junction compensation for the core are handled by the JA pin of connectors JAR/S/T on the TBQA board. 4-20 mA input and output signals are transmitted via JB to the JBR terminal board on TBQC. The JD connector sends trip signals from the core to the TCTG board in the core, while the JE connector transfers pulse signals, generator and line signals, relay driver outputs, servo valve driver outputs, and power monitor inputs to and from the TCQC board. Additionally, the JFR connector on the TBQC terminal board sends LVDT/LVDR position inputs to JF, and JG carries +/-10 V DC inputs and vibration inputs from the JGR connection on the TBQB terminal board.
