Control is PID or On/Off, fed from a 24 VAC/DC supply. Outputs include four relay contacts, one analog signal, and a voltage output for an external SSR — enough to drive a heater, valve, or alarm string. The display is a backlit LCD with tri‑color characters; character heights are 0.710\", 0.433\", and 0.307\" for three rows of four digits each. Rated IP66 from the front — dust tight and water resistant, so it holds up in a washdown panel environment. This controller is active with no end-of-life notice. It remains available through normal distribution. ## Cross‑reference note: E5CC‑CQ3D5M‑005 vs this E5EC The closest functional sibling is the E5CC‑CQ3D5M‑005, which has the same input range, control method, supply voltage, and IP66 rating. However, the E5CC uses a square 45 × 45 mm panel cutout, while this E5EC requires a rectangular 92 × 45 mm opening. The E5CC also carries three relay outputs versus four here, and adds an event input. It is not a drop‑in replacement — if your panel is cut for an E5CC, the E5EC will not fit without rework. For a new build or panel redesign, the E5EC gives one more relay and a larger display with three character sizes. The extra relay can serve as a second alarm or a backup control output without needing an external module.","metaTitle":"Omron E5EC-CQ4D5M-000 Temperature Controller, 24V, PID, 4 Re","metaDescription":"Active production Omron E5EC-CQ4D5M-000 process/temperature controller. 24VAC/DC supply, PID control, 4 relay outputs, analog, voltage SSR.
