IS200TBCIH2C – Conduction Sensor board

The IS200TBCIH2C is a Conduction Sensor Board used in the GE Mark VIe control system platform. This terminal board plays a key role in acquiring discrete signals from field devices such as switches, relays, and other conduction-type sensors. It is designed with high reliability and group isolation, making it suitable for demanding applications in power plants and industrial automation environments.

This board provides up to 24 contact inputs, grouped electrically to allow efficient wiring and electrical isolation. It is intended for use in conjunction with compatible discrete I/O packs such as the IS220PDIAH1A, allowing the system to read the on/off status of connected devices. The IS200TBCIH2C ensures that each signal is properly conditioned and isolated before being fed into the control logic of the Mark VIe system.

The terminal board utilizes DIN rail mounting, enabling compact and easy installation within control cabinets. The board is equipped with pluggable terminal blocks to support fast and secure wiring of field devices, simplifying both installation and maintenance. A key feature of this board is its group isolation, which improves fault containment and enhances system reliability by ensuring that a short or ground fault on one group of channels does not affect others.

Built to withstand the harsh operating conditions typically found in turbine and industrial control systems, the IS200TBCIH2C maintains performance over a wide range of temperatures, humidity levels, and vibration environments. It complies with industry standards for electromagnetic compatibility (EMC) and safety, ensuring dependable long-term service in mission-critical applications.

In turbine systems, it is commonly used to receive input signals from devices like pressure switches, limit switches, or emergency stop circuits. Its modular design and compatibility with other GE Mark VIe components make it a flexible and essential element in complex control architectures.
