Allen-Bradley 1771-IXHR Thermocouple Input Module

The Allen-Bradley 1771-IXHR High-Resolution Thermocouple/Millivolt Input Module is an eight-channel analog I/O card for PLC-5 systems, designed to plug into a 1771 I/O backplane and feed thermocouple or millivolt signals into the controller. It provides eight differential inputs that convert thermocouple and millivolt signals to PLC-5 compatible digital values, enabling precise temperature measurements across multiple process points. The IXHR supports a range of thermocouple types (including B, E, J, K, R, S, T) and millivolt inputs, making it suitable for diverse temperature monitoring applications in industrial automation. Catalog number 1771-IXHR places it within the PLC-5 1771 I/O lineup for high-resolution thermal data in automation environments.
