Product Description

Product Overview

The GE IS200TBCIH2CCD is a Contact Input with Group Isolation (TBCI) terminal board designed for GE Mark VI Speedtronic turbine control systems. It provides a reliable interface between field contact devices and the turbine control system.

The board supports up to 24 discrete contact inputs and provides organized field wiring through two barrier-type terminal blocks. Its input circuits include filtering and surge suppression to help reduce electrical noise and transient interference.

The H2 configuration is associated with 24 VDC nominal contact excitation. The board supports Simplex and Triple Modular Redundant (TMR) configurations, depending on the overall control system architecture and connected I/O equipment.
