Product Overview
IS230TVBAH2A is a thermocouple input terminal board within the GE IS230 series, built for the Mark VIe Speedtronic turbine control system. It functions as the field signal interface to capture temperature readings from thermocouple sensors, converting low millivolt signals and forwarding processed temperature data to the Mark VIe VTCC processor.
This terminal board belongs to the TMR triple modular redundant I/O assembly for gas and steam turbine control. It comes with two barrier terminal strips TB1 and TB2, each offering 24 thermocouple input points, delivering a total of 48 channels. It supports both grounded and ungrounded E, J, K, T type thermocouples. The PCB has conformal coating to resist dust, humidity and vibration inside power plant control cabinets. The terminal blocks can be detached for convenient field wiring and maintenance.
