GE IS230PCAAH1B Core Analog Module
The IS230PCAAH1B Core Analog (PCAA) module and associated Core Analog (TCAS and TCAT) terminal board provide a large portion of the analog signal I/O required to operate a gas turbine. PCAA and TCAT provide thermocouple inputs, 4-20 mA current loop I/O, seismic inputs, Linear Variable Differential Transformer (LVDT) excitation and inputs, pulse rate inputs, and servo coil outputs. PCAA may be applied in simplex, dual, and TMR systems. A single TCAT terminal board fans signal inputs to one, two, or three connected PCAA modules. The shield ground and 24 V field power terminals on an adjacent JGPA board supplement the terminals on PCAA and TCAT.
PCAA contains a processor board common to all Mark* VIe distributed I/O, two application I/O boards, and a terminal board. The complete module is regarded as the least replaceable unit and there is no support provided to diagnose or replace the individual boards making up the module.
Input to the module is through dual RJ45 Ethernet connectors and 28 V dc power connector P5. Field device I/O is through 120 Euro-style box terminals on the module edge. Power for a JG PA board is through connector P4. Module connection to TCAT is through two 68-pin cables on connectors P1 and P2.
The signals on PCAA are separated into two groups. Signal inputs that may be fanned from a single input into a single, dual, or TMR PCAA modules are routed through the TCAT terminal board. Signals that are dedicated to a single PCAA module are wired to the terminals on PCAA. This creates the signal split shown in the following table. It is possible to use PCAA without TCAT if the fanned inputs are not required.
