IS200VCRCH1BBB

Product Description

Mark VI General Electric module IS200VCRCH1BBB is a Discrete Input/Output Terminal Processor Board. The VCRC model is functionally the same as the VCCC model, but this unit is a single-slot version, while the VCCC model is a dual-slot model with a daughterboard. When the VCRC model is mounted in the Mark VI cabinet, it takes up less space as there is no daughterboard. This model has forty-eight inputs labeled as contact inputs that come from the TBCI model, and the outputs, of which there are twenty-four, come from the TRLY board; twelve of the outputs are solenoid outputs; the remaining twelve are dry contact relay outputs. 

One of the main differences between the IS200VCRCH1BBB model and the VCCC model is the location of the connectors for the contact inputs boards for the VCRC model; the connectors are located on the front of the model and labeled J33 and J44 on the front faceplate of the model. There are also three status LEDs available on the front faceplate of this model. The LEDs are labeled RUN, FAIL, and STATUS with their own corresponding color. The FAIL LED is solid red, the RUN LED will flash green, and the STATUS LED is normally off but will be a steady orange when a diagnostic alarm condition occurs. 

The IS200VCRCH1BBB model can be used in triple modular redundant (TMR) or simplex applications. When the model is in a TMR application, the contact input voltages will be fanned out to three VME board racks, such as the R, S, and T racks, through the JR1, JS1, and JT1 plugs on the VCRC board.
