Allen-Bradley 1771-IXHR Thermocouple Input Module

The Allen-Bradley 1771-IXHR High Resolution Thermocouple/Millivolt Input Module is a PLC-5 I/O module that provides eight floating differential inputs for thermocouple and millivolt signals within 1771 I/O chassis. It supports thermocouple types B, E, J, K, T, R, and S, and includes a ±100 mV millivolt input range, enabling precise multi-sensor temperature measurement across common industrial sensors. As a high-resolution input module designed for the PLC-5 system, the 1771-IXHR can be used in any 1771 I/O chassis, and its eight channels allow simultaneous monitoring of multiple thermocouple signals, making it well suited for process temperature monitoring, furnaces, kilns, and other temperature-critical automation tasks that rely on PLC-5 controllers.
