Information About IS200TBCIH2B

The IS200TBCIH2B is part of GE’s Mark VIe series and functions as a Contact Input with Group Isolation board designed to support up to twenty-four dry contact signals. Its group-isolated architecture enhances safety and signal accuracy by minimizing cross-interference between inputs. The module supports both cable and J-Port connections, allowing flexible integration into existing Mark VIe installations. Measuring 13 inches by 4 inches, the board offers a compact form factor suitable for dense control cabinet layouts, and it serves as a direct replacement for the TBCIH2C module.
