Product Overview
IS200TCASH1A (TCAS) is field‑wiring terminal board for GE Mark VIe turbine control packs. It serves as physical interface between field sensors and BCAA/BCAB analog processing modules. It terminates thermocouple temperature sensors, 4‑20 mA transmitters and LVDT valve‑position sensors, routes conditioned signals via high‑density back‑connectors to I/O processing boards. It also provides 28 V DC auxiliary power for JGPA cable‑shield termination board.
Important note: This is only terminal interface board, no onboard A/D conversion. It cannot work standalone; must pair with BCAA or BCAB analog I/O module.
