The IS200TCASH1A is a terminal board developed by General Electric. It is a part of the Mark VIe series. Customer terminals and signal routing into the BCAA and BCAB boards are provided by this terminal board. The P5 connector on TCAS accepts bulk 28 V control power. It then supplies power to a JGPA board in the input cable shield termination location via connector P4. P1 and P2 68 pin connectors for terminal board cables are available from TCAS. The TCAS terminal board within the module routes signals to connectors for the BCAA and BCAB analog processing boards.
