What this controller fits
The Omron E5EC-TCX4D5M-000 is a panel-mount process and temperature controller from the E5EC-T series, accepting inputs from RTDs and thermocouples (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 — so it covers both temperature loops and linear process signals on one unit. It runs on a 24 VAC/DC supply and delivers control via four relay outputs plus an analog output, with On/Off or PID control methods selectable per loop.
Key ratings and what they mean for your panel
The IP66 front-panel rating means the controller face is dust-tight and protected against hose-directed water — suitable for washdown environments in food, beverage, or chemical processing without needing a secondary cover. Panel cutout is 92.00 mm x 45.00 mm rectangular, a standard 1/4 DIN size that fits existing punch patterns and leaves room for the screw-terminal connections on the rear. The LCD display shows three rows of four characters each, with character heights of 18.00 mm, 11.00 mm, and 7.80 mm — the top row is large enough to read the process value from across a control cabinet. Operating temperature range is -10°C to 55°C, which covers most indoor industrial environments but not extended freezer or oven-adjacent mounting without thermal isolation.
