Our PID controllers offer industry-leading features and reliable performance designed for the most demanding applications.

Panel Mount Controllers

PAX®2C Series

The Red Lion PAX®2C PID controllers offer universal inputs, including thermocouples, RTDs, process signals, DC current/voltage and resistance. Available in 1/8 DIN size models, PAX2C controllers work with field-installable option cards to seamlessly support changing applications and upgrade requirements. Learn more.

PXU Series

Red Lion’s PXU series enables tighter, more reliable control over a wide range of processes from a single PID controller. Available in 1/16, 1/8 and 1/4 DIN size models, the PXU series accepts process, thermocouple and RTD signals and presents values on one of the industry’s largest dual displays. Available options include DC analog control, RS-485 communication and user inputs. Learn more.

T48/P48 Series

Red Lion’s T48/P48 PID controllers accept signals from a variety of temperature or process inputs. Available in 1/16 DIN size models, T48/P48 controllers provide options that include various alarms and output configurations, heater current monitor and remote setpoint. Features include manual override and RS-485 communications. Learn more.

TSC/PSC Series

The Red Lion TSC/PSC series is a setpoint program controller for time versus temperature (ramp/soak) applications. It accepts signals from a variety of temperature or process inputs. Available options include dual event outputs and alarms, quad setpoint, cooling, linear DC and field replaceable output modules. Features include manual override and RS-485 communications. Learn more.

DIN Rail Mount Controllers

Modular Controller Series

The Modular Controller series from Red Lion allows users to seamlessly integrate multi-zone PID control, data acquisition and I/O into PC, DCS or PLC control systems. Stack up to 16 hot swappable modules together for an easy space saving solution. Available features include protocol conversion, built-in web and FTP servers. Learn more.

DLC Series

Red Lion’s Dual Loop Controllers (DLC) offer dual independent PID control loops to provide multi-zone process control. The DLC series accepts signals from both temperature and process inputs and supports square root extraction flow sensor applications, dual analog output control and RS-485 communications.
