I/O modules

This versatile input output board handles mixed signal types for turbine control applications. The GE IS200VCRCH1B IS200VCRCH1BBB combines digital inputs, digital outputs, and analog channels on one assembly. Eight discrete inputs accept 24V DC signals from field devices. Consequently, operators can monitor contact closures, limit switches, and proximity sensors directly.

Technical Specifications of the Input Output Board

The GE IS200VCRCH1B IS200VCRCH1BBB fits a standard VME 6U form factor seamlessly. Its height measures 233.4 mm, and its depth reaches 160 mm. The board weighs approximately 0.65 kg including all components and connectors. A single front panel LED array shows channel status for each I/O point. The rear side uses a 64-pin DIN 41612 connector for backplane power and signals. This design stores minimal energy in small filtering capacitors only. Therefore, the board contains no batteries or large energy storage elements.

Functional Features and Signal Mixing

The GE IS200VCRCH1B IS200VCRCH1BBB provides optical isolation for all digital input channels. You can configure the analog inputs for voltage or current measurements independently. Each digital output includes short-circuit protection and status feedback monitoring. The onboard firmware scans all I/O points within a single control cycle. Consequently, the board delivers real-time data without communication delays.

Installation and System Integration

You must install this input output board into any standard VME backplane chassis. The GE IS200VCRCH1B IS200VCRCH1BBB requires no field wiring connections directly on the board. Instead, use a compatible termination panel like the IS200TVIBH2B for all sensor and actuator wiring. A 64-pin ribbon cable links the board to the termination panel securely. Always verify voltage levels before connecting field devices to the system.

Maintenance and Operational Benefits

Because the GE IS200VCRCH1B IS200VCRCH1BBB stores no battery-backed data, it requires no periodic battery replacement. Technicians can remove and reinstall the board without losing configuration settings. The Flash memory retains all channel assignments and scaling parameters indefinitely. Consequently, system maintenance becomes simpler and less time-consuming compared to battery-dependent designs.
