GE Mark VI IS200VCRCH1BBB Discrete Input/Output Board

Description

The IS200VCRCH1BBB is a Discrete Input/Output Terminal Processor Board used in the Mark VI General Electric turbine control system. This board is functionally similar to the VCCC model, with the main difference being that the VCRC is a single-slot version, unlike the dual-slot VCCC which includes a daughterboard. This design allows the VCRC to occupy less space when mounted in the Mark VI cabinet.

Technical Specifications

• Instruction Manual: GEH-6421 Volumes I and II Mark VI System Guide
• Part Number: IS200VCRCH1BBB
• Series: Mark VI IS200 Turbine Control System
• Manufacturer: General Electric Company USA, GE Industrial Systems
• Product Type: I/O Processor Board
• Functional Description: Discrete Input/Output Board
• Abbreviation/Functional Acronym: VCRC
• Number of Discrete Inputs: 48 Discrete Contact Inputs
• Number of Outputs: 24 Relay Solenoid Outputs

Key Features:

• Inputs and Outputs: The IS200VCRCH1BBB has 48 contact inputs, which are received from the TBCI model, and 24 outputs. Of these outputs, 12 are solenoid outputs, and the other 12 are dry contact relay outputs, interfaced through the TRLY board.
• Connector Locations: Unlike the VCCC model, the VCRC's contact input connectors are positioned on the front of the module, labeled as J33 and J44 on the front faceplate.
• Status Indicators: The front faceplate includes three LEDs for status indication: RUN (flashes green), FAIL (solid red), and STATUS (normally off but steady orange during a diagnostic alarm condition).
• Applications: The IS200VCRCH1BBB can be used in both triple modular redundant (TMR) and simplex applications. In TMR applications, contact input voltages are distributed to three VME board racks (R, S, and T) via JR1, JS1, and JT1 plugs on the VCRC board.
