Allen-Bradley 1771-IXE Thermocouple Millivolt Input Module

Allen-Bradley 1771-IXE Thermocouple/Millivolt Input Module is an eight-channel analog input module for PLC-5 systems, delivering eight differential inputs that accept thermocouple or millivolt signals for direct temperature measurement or low-level signal monitoring. It supports thermocouple types E, J, K, R, S, and T with a full-scale input range up to ±99.99 mV, enabling precise reading of small voltage signals without additional conditioning. Readouts can be provided as actual temperature or millivolt values, and may be presented in Natural Binary or BCD formats depending on configuration, facilitating straightforward integration with existing AB software and hardware. The module, identified by firmware revision B (FW. REV: B 1771-IXE), is designed to work with Rockwell Automation backplane and Block Transfer-capable PLCs, offering reliable channelized sensing for temperature control, process monitoring, and low-level signal acquisition in rugged industrial environments.
