The Omron E5CC-QX3D5M-001 is a 1/16 DIN panel-mount process and temperature controller that accepts RTD and thermocouple inputs (Types B, E, J, K, L, N, PLII, R, S, T, U, W) as well as 0–20 mA or 0–10 VDC analog signals, covering a span from -200°C to 2300°C. It runs on a universal 24 VAC/DC supply, so a single PSU rail can power it alongside other 24 V panel gear without needing a separate transformer tap. Control is either on/off or proportional (PID), with three relay outputs and a voltage output for driving an external SSR — enough for a heating element plus an alarm or cooling fan. The IP66-rated front panel (dust-tight and water-resistant) means it survives washdowns and humid enclosures, though the screw terminals on the rear still need a clean, dry environment.
Key features for the panel builder
Event Input and Heater Fault Detection are built in — the event input lets an external dry contact switch between two setpoints or start/stop the control, and the heater fault function monitors current draw to flag a broken element or SSR short. The dual-color LCD backlight shows two rows of four characters each (0.600" and 0.280" heights), making process value and setpoint readable at a glance even in low light.
