The Omron E5EC-TRR4A5M-000 is a panel-mount process and temperature controller from the E5EC-T series, handling RTD, thermocouple (Types B, E, J, K, L, N, PLII, R, S, T, U, W), 0-20 mA, and 0-10 VDC inputs across a range of -200°C to 2300°C. It drives six relay outputs for multi-stage or multi-zone control — think heating/cooling pairs, alarm annunciation, or cascaded PID loops — and runs on a universal 100-240 VAC supply. Control methods include On/Off and full PID, with a tri-color LCD backlight that shifts color to indicate status at a glance.
The panel cutout is a standard 92.00 mm x 45.00 mm rectangle — same footprint as the rest of the E5EC family, so it drops into an existing DIN-rail enclosure cutout without rework. Screw-terminal wiring, IP66 front-panel seal. That IP66 rating means the face survives washdown splashes and dusty plant floors — common in food, pharma, and packaging lines.
