Red Lion Controls PXU11A20 Industrial Automation Module

The Red Lion PXU11A20 is a 1/16 DIN PID temperature controller in the PXU family, built for simple yet reliable process control with universal sensor input. It provides dual relay outputs for independent control of actuators or alarms and includes RS-485 communications for programming and remote monitoring via Crimson software. The unit offers two user inputs for local adjustments and a large dual-line display (four digits per line) for easy on‑screen visibility, all in a compact, panel‑mountable design powered from AC mains. As a universal-input controller, the PXU11A20 supports a range of sensor types—including RTDs, thermocouples, and other transducers—making it versatile for temperature and general process control applications. Typical uses include temperature regulation in industrial heating or cooling stages, process temperature tracking in packaging or manufacturing lines, and other small to mid‑scale control tasks where space is at a premium. For configuration, Crimson software provides setup and parameter management, with RS-485 as the communication option required to enable Crimson programming and remote data access.
