Description
Product Overview
The GE IS230PCAAH1B Core Analog Module from the Mark VIe Series delivers high-density analog I/O for gas turbine control systems. It integrates thermocouple inputs, seismic sensors, LVDT excitation, pulse rate inputs, and servo coil outputs. This module supports simplex, dual, and TMR configurations and connects to TCAT and TCAS terminal boards for fanned signal distribution.
Its rugged design includes dual RJ45 Ethernet ports, 28V DC power input, and 120 Euro-style terminals for field wiring. The module houses a processor board, two application I/O boards, and a terminal board, forming a complete, non-serviceable unit.
