IS230TNSVH3A

Product Overview

IS230TNSVH3A is a thermocouple input terminal board belonging to GE IS230 series, designed for Mark VIe Speedtronic turbine control systems. It serves as the field signal interface for temperature measurement, accepting E, J, K, T type thermocouple sensors to feed real-time temperature data back to the Mark VIe controller.

This terminal board is part of the TMR triple modular redundant I/O pack used on gas and steam turbines. It converts thermocouple low-level millivolt signals into readable digital data for turbine monitoring, over-temperature protection and process interlock control. The PCB adopts conformal coating to resist dust, moisture and vibration inside power plant control cabinets. The board is equipped with two barrier terminal strips (TB1 & TB2), each supporting 24 thermocouple input points, and supports grounded or ungrounded thermocouple wiring.
