General Electric IS230PCAAH1A SPEEDTRONIC Turbine Control.The PCAA module has 120 Euro-style pluggable box terminals. A JGPA board, which mounts next to the module, provides 48 shield termination points (green) and twelve 24 V dc output terminals (orange) for 4-20 mA transmitters using Euro-style box terminals./Part Number: IS230STAIH2A Manufacturer: General Electric Series: Mark VIe Function: TERMINAL BOARD/General Electric Speedtronic Mark VIe IS230PCAAH1A Analog I/O Assembly Terminal Board is a part of gas turbine Control Systems /GE IS230PCAAH1A
Functional Description
The module is suitable for use in simplex, dual, and TMR systems. A single TCAT terminal board distributes signal inputs to one, two, or three PCAA modules.
An adjacent JGPA board’s shield ground and 24 V field power terminals supplement the terminals on PCAA and TCAT. Module includes a processor board that is shared by all Mark VIe distributed I/O boards, two application I/O boards, and a terminal board.
The entire module is regarded as the least replaceable unit, and no assistance is provided to diagnose or replace the individual boards that comprise the module.
The module is powered by a 28 V dc power connector and two RJ45 Ethernet connectors. On the module’s edge, 120 Euro-style box terminals provide field device I/O. Power is supplied to a JGPA board via connector P4. The module is connected to TCAT via two 68-pin cables on connectors P1 and P2.
