Description
Overview
The IS200VCRCH1BBC and IS200VCRCH1B modules are discrete I/O printed circuit boards designed for GE’s Mark VIe control platform. Both variants provide high‑density digital input and relay output capability for turbine and process control systems. The boards deliver the same functional performance as the VCCC module but in a more compact, single‑slot form factor, making them suitable for installations with limited rack space.
Technical Specifications
These boards support a large number of discrete channels and incorporate a dense component layout optimized for high‑speed signal processing. The IS200VCRCH1B version includes a daughterboard interface for terminal board connectivity, while the IS200VCRCH1BBC variant eliminates the daughterboard to reduce footprint.

Functional Characteristics
The boards incorporate more than sixty integrated circuits—including FPGAs, CMOS logic, and SRAM—along with over thirty transistors to support high‑density digital processing. The IS200VCRCH1BBC variant routes all cabling through the front panel, while the IS200VCRCH1B supports daughterboard connectivity for installations requiring terminal board interfacing.
Only the first two revisions of the IS200VCRCH1B maintain backward compatibility with earlier VCCC modules, making revision selection important during system upgrades. Both models are engineered for VME rack mounting and include conformal coating for environmental protection.
Application Scenarios
These modules are commonly used in:
-
Gas turbine and steam turbine control
-
High‑density discrete I/O applications
-
Mark VIe rack‑based control systems
-
Space‑constrained installations requiring single‑slot I/O boards
-
Systems requiring 48 DI / 24 relay output capability
FAQ
