Overview
Red Lion Controls PAX2C is a compact 1/8 DIN panel-mount PID controller designed for precise temperature and process control across industrial applications. The PAX2C offers universal inputs, including thermocouples, RTDs, process signals, DC current/voltage and resistance, to provide an all-in-one platform that simplifies integration. Applications include food & beverage, plastics, packaging, energy, gas, heat treating and glass processing.
Key Features
- Tri-color LCD display with programmable dual-line output and units, bar graph, four programmable universal annunciators, and seven programmable color zones
- PID control with reduced overshoot and support for field-installable FlexCard and standard option cards
- Built-in USB programming port enabling unit configuration with Crimson programming software
- Up to 16 alarms with boolean logic functionality
- Field installable option cards for setpoints, communication, and retransmitted analog output
- On/Off and Proportional (PID) control modes
Technical Specifications
The Red Lion Controls PAX2C controller supports a wide range of input types and voltage ratings to accommodate diverse industrial environments:
Typical Applications
The PAX2C is used in food & beverage, plastics, packaging, energy, gas, heat treating and glass processing applications. The universal input capability allows the controller to be deployed in thermal processing, HVAC systems, refrigeration, batch ovens, autoclave control, and any process requiring precise temperature or analog signal regulation. The dual-line display and programmable annunciators make it suitable for complex multi-zone monitoring and alarm management in industrial settings.
