Overview

The Allen-Bradley 1771-IXHR Thermocouple Millivolt Input Module is part of the PLC-5 I/O family, designed to provide accurate temperature measurement and millivolt signal input for industrial processes. It interfaces directly with thermocouples and other millivolt-generating devices, converting signals into digital values for use in PLC-5 controllers. Moreover, its high-resolution design ensures precise monitoring, while reinforced isolation guarantees safe and reliable operation in demanding environments. Engineers value its accuracy and flexibility, while operators benefit from simplified integration into existing PLC-5 systems.
