PRODUCT INFORMATION
Product Overview
The General Electric IS200VCRCH1BBB is an I/O Processor Board for the Mark VI / Mark VIe family. This board operates natively within Mark VI Turbine Control System VME racks. It functions as a discrete input and output terminal processor in turbine automation systems. The assembly controls discrete signal paths for gas, steam, and wind turbine drive installations. It provides a single-slot form factor without requiring an auxiliary daughterboard.
The IS200VCRCH1BBB board accepts forty-eight discrete contact inputs from a TBCI terminal board. It manages twenty-four outputs connected through an associated TRLY relay board. These outputs comprise twelve solenoid outputs and twelve dry contact relay outputs. Three front diagnostic LEDs indicate operational RUN, FAIL, and STATUS conditions. The board supports both simplex architectures and triple modular redundant control configurations.

PRODUCT FAQ
Frequently Asked Questions
What is the primary function of the IS200VCRCH1BBB board?
The board processes 48 discrete contact inputs and 24 relay or solenoid outputs for Mark VI systems.
How does the IS200VCRCH1BBB differ from the VCCC module?
The IS200VCRCH1BBB uses a single slot without a daughterboard and provides front J33 and J44 connectors.
Can the IS200VCRCH1BBB operate in triple modular redundant systems?
Yes, it fans contact inputs to R, S, and T racks using JR1, JS1, and JT1 plugs.
What do the front diagnostic LEDs indicate on this board?
A solid red LED shows FAIL, flashing green indicates RUN, and steady orange indicates diagnostic STATUS.
