What this controller handles
The E5EC-TCX4A5M-022 is a multi-input process and temperature controller from Omron's E5EC-T series, accepting RTD, thermocouple types B/E/J/K/L/N/PLII/R/S/T/U/W, plus 0–20 mA and 0–10 VDC analog signals across a span of -200°C to 2300°C. Control is On/Off or proportional (PID) with four relay outputs and an analog output for retransmission or secondary loop drive. The RS-485 port supports both CompoWay/F and Modbus protocols, so it drops into existing PLC or SCADA networks without a protocol converter.
Panel fit and environmental sealing
Panel mount with a 92.00 mm x 45.00 mm rectangular cutout, screw-terminal wiring, and an IP66-rated front face that resists washdown and dust ingress — suitable for food, beverage, or chemical environments where hose-down cleaning is routine. Operating range is -10°C to 55°C, so it lives in a conditioned panel or cabinet, not outdoors in direct sun.
Lifecycle and sourcing posture
Omron lists this part as Active. It is not approaching end-of-life, so no last-time-buy scramble — production quantities are quoted to order against the BOM through authorized distribution. The tri-color LCD backlight and three character heights (18.00 mm, 11.00 mm, 7.80 mm) give clear readouts at distance; the event input lets a dry contact trigger a preset recipe or alarm override without touching the front panel.
