Red Lion Crimson programmed PAX2C PID controllers are dual-line displays that change color based on process status, alerting when a value is out of a specified range. The controllers accept DC current, DC voltages, process signals, thermocouples and RTD inputs. Inserting a field-installable Red Lion FlexCard module allows populating the controllers in more than 150 configurations to monitor and control multiple application processes on a single display. The solution is suitable for temperature, flow and pressure control in packaging, food and beverage applications.
