GE IS220YTCCS1A Mark VIeS Safety Thermocouple Input Pack

GE IS220YTCCS1A is a core safety I/O module in GE’s Mark VIeS distributed turbine control system, designed for high‑reliability temperature monitoring in gas/steam turbine safety 

applications. It provides 12 isolated thermocouple input channels, supporting E, J, K, S, T types with grounded/ungrounded configurations, and offers °C/°F unit selection. The module 

interfaces with IONets and terminal boards (e.g., IS200STTCS1A, IS400STTCS1A), enabling system scaling to 24 channels via dual‑pack configuration. It features 28V DC power input, 

-8mV to 45mV input voltage range, and complies with safety standards for turbine protection systems. Built for industrial harsh environments, it is widely used in gas turbine ESD, F&G,

 and critical temperature monitoring. New, refurbished, and repair services are available with warranty.
