The General Electric IS200VCRCH1BBB and IS200VCRCH1B Digital Cards support Mark VIe turbine control systems with high‑density discrete I/O processing. These boards manage 48 contact inputs and 24 relay outputs, enabling precise control in gas and steam turbine applications. Their compact single‑slot design improves cabinet efficiency while maintaining full compatibility with GE Speedtronic architectures.
Functional Design
The GE IS200VCRCH1BBB and IS200VCRCH1B receive input signals from TBCI terminal boards and route output signals to TRLY boards. Their front‑panel connectors (J33 and J44) and diagnostic LEDs provide clear visibility of RUN, FAIL, and STATUS conditions. The single‑slot VCRC layout reduces panel space requirements compared to the dual‑slot VCCC model.
