GE FANUC IS200VCRCH1BBB Discrete I/O Board

Description

The GE FANUC IS200VCRCH1BBB is an analog I/O board belonging to the Mark V series, designed specifically for gas turbine control systems. Its core function is to scale and condition a wide range of analog signals read from terminal boards mounted on I/O cores R1, R2, and R3 (TCQA). Supported signal types include LVDT inputs, servo valve outputs, thermocouple inputs and outputs, 4-20 mA inputs and outputs, vibration inputs, relay driver outputs, pulse inputs, voltage inputs, and generator and line signals.

This board features dedicated connectivity for system integration: partial signals are written to the STCA board via a 3PL connection, while a JE connection enables communication with the TCQC board by sending and receiving generator and line signals. The paired TCQA board handles scaling and conditioning of 4-20 mA input signals for applications such as compressor stall detection and fuel flow pressure monitoring.

Configurable hardware jumpers enhance its flexibility: J1 and J2 select mA output circuits, J5 and J6 set mA output current ranges to either 20 mA or 200 mA, J7 enables card testing via an RS232 port, and J8 activates the oscillator. Jumper setup details are available in appendix A and the operator interface hardware jumper panel documentation.
