IS200TBCIH1B IS200TBCIH1BBC

The GE IS200TBCIH1B Terminal Breaker Contact Input (TBCI) Interface Module is a dedicated discrete input board engineered for integration within GE Mark VI and EX2100 turbine and excitation control systems. This module plays a pivotal role in capturing breaker auxiliary contacts, status signals, and interlock feedback from field devices and converting them into conditioned logic signals suitable for high-reliability control processing.

In power generation and heavy industrial environments, accurate breaker state recognition is critical for protection logic, sequencing, and safety interlocks. The IS200TBCIH1B ensures stable signal interpretation through isolation buffering and filtering technologies, minimizing the risks associated with electrical noise, contact bounce, and transient disturbances. Its robust architecture supports long-term operational reliability in demanding plant conditions.
