GE IS220PTCCH1B is a thermocouple input module. This module is designed to receive thermocouple signals and convert them into standard electrical signals for further processing. It is particularly suitable for industrial automation and control systems for measuring and monitoring temperature. The differential input design can effectively reduce interference and noise between channels and improve signal accuracy and reliability.

The IS220PTCCH1B supports simplex, duplex, and triplex redundant applications. The board accommodates common thermocouples such as E, J, K, S, and T, as well as millivolt inputs from -8 to 45 mV. Thermocouples such as E, J, K, S, and T can be grounded or ungrounded and can be placed up to 984 feet from the turbine I/O panel. Cable resistance must not exceed 450 ohms.
