Red Lion Controls PCU11108 Control Unit

Red Lion PCU11108 is a panel‑mount process control unit designed for 115/230 VAC operation that accepts 0–10 VDC or 0–20 mA analog inputs and delivers precise control through field‑replaceable output modules for the main output, alarms, and a possible secondary output. The controller supports both On/Off and PID control with on‑demand auto‑tuning, plus local/remote setpoint and manual/auto operation to suit a range of process applications. It features dual 4‑digit LED displays for simultaneous viewing of process value and setpoint, complemented by front‑panel indicators, and is housed with a front bezel sealed to IP65/NEMA 4X for challenging environments. Panel installation requires a 92 mm × 45 mm cutout, and termination is via screw terminals, with a total weight around 1.3 lb (589.7 g). While the PCU11108 offered optional RS485 serial communications and configurable alarm outputs, its production has been discontinued and the unit is now listed as obsolete, with Red Lion’s PCU family providing current‑generation substitutions for ongoing support.
