About the IS200VCRCH1ABA

The IS200VCRCH1ABA  model is described as a Discrete Input/Output module. It was produced by General Electric to operate in the Mark VI series. The VCRC model has an alternate board; the alternate board is known as a VCCC board. The VCRC board has the same functionality as the VCCC board; one minor difference between the two models is contact input cables; the contact input cables on the VCRC board will plug into the front of the board. Another difference between the IS200VCRCH1ABA  model and the VCCC model is that the VCRC model is considered a single-slot version of the VCCC board. 

When the model is being operated, the input/output (I/O) signal types used with this model are solenoid and dry contact relay outputs and contact inputs. There are 48 contact inputs per processor, with twenty-four outputs between the dry contact relay and solenoid outputs, twelve for each output type. There are two different associated terminal boards for the inputs and outputs on the IS200VCRCH1ABA  model; the associated board used with the outputs is the TRLY board, and the board used with the inputs is the TBCI board. When the terminal boards are used with the VCRC board, they will connect to the model through the J3 and J4 connectors located on the front faceplate of the unit. 

It should be noted that while the IS200VCRCH1ABA model has the same functionality as the VCCC model, it cannot be used with a TICI contact voltage sensing board like the VCCC unit can. For more information on what other Mark VI boards can be used with the VCRC unit, refer to the GEH-6421 Mark VI Turbine Control System Guide Volume II.
