What the E5EC-TCX4D5M-005 covers
The Omron E5EC-TCX4D5M-005 is a 1/4 DIN panel-mount process and temperature controller from the E5EC-T series, accepting RTD inputs, thirteen thermocouple types (B, E, J, K, L, N, PLII, R, S, T, U, W), plus 0–20 mA and 0–10 VDC analog signals — so it handles everything from a Type K furnace thermocouple to a 4-20 mA pressure transmitter on the same unit without an external signal conditioner. The input range spans -200°C to 2300°C for temperature sensors and 0–20 mA / 0–10 VDC for process signals, making it a single-BOM-line solution for machines that mix temperature zones and analog transducers.
Outputs and control loop
Four relay outputs handle on/off or time-proportional PID control for heaters, solenoid valves, or alarms, while the analog output drives an external SSR or a 0-10 VDC positioner — typical for a valve actuator or SCR power controller. Control method is selectable between on/off and proportional (PID), with autotune available during commissioning to set P, I, and D terms without manual loop calculations.
Mounts in a 92.00 mm × 45.00 mm rectangular panel cutout — the standard 1/4 DIN footprint — and secures with screw terminals for field wiring. The IP66 front-panel rating means the display and keypad withstand direct hose spray and dust ingress, so it can live on a washdown food-processing line or a dusty packaging machine without a separate enclosure door.
Display and event input
The LCD shows three rows of tri-color characters (four digits per row) with character heights of 0.710", 0.433", and 0.307" — the top row is large enough to read the process value from across a machine cell. An event input lets an external dry contact trigger a preset function (run/hold, alarm acknowledge, setpoint switch) without opening the front panel.
Power supply and lifecycle
Runs on 24 VAC or 24 VDC — universal supply simplifies panel wiring and means one controller works on both AC and DC control buses.
