Description
GE IS200TBCIS2CCD is a dedicated contact input termination board developed for the GE Speedtronic Mark VI gas and steam turbine control platform. It acts as the physical interface between field-mounted contact switches, limit switches and auxiliary relays and the internal I/O processing modules inside the control rack. Onboard filtering circuits suppress electromagnetic interference and transient voltage spikes to improve signal stability in noisy power plant environments. This board is widely used as replacement spare hardware for legacy turbine control systems in thermal power plants, refineries and combined-cycle power facilities.
Series
The Speedtronic Mark VI platform is GE’s mature turbine control solution for rotating machinery. The system consists of main control processors, I/O packs and matching terminal boards including IS200 series termination assemblies to realize field signal wiring and signal conditioning.
Product Features
- Screw terminal block design for convenient field wiring of discrete contact input signals.
- Integrated RC filter and surge protection circuits to reduce high-frequency noise and transient disturbances.
- Grouped signal isolation design to minimize cross-channel interference.
- Multiple high-density ribbon connectors to establish communication with corresponding Mark VI I/O packs.
- Standard horizontal rack mounting structure matching Mark VI control cabinet layout.
- Rugged industrial PCB construction suitable for continuous operation in power plant control rooms.
- Supports both simplex and TMR (Triple Modular Redundant) Mark VI control architectures.
- End-of-life legacy component; not available for new turbine control project deployment.
