Control output is a mix of five relay contacts for on/off or alarm duties and a voltage pulse for driving an external solid-state relay, giving you the flexibility to switch contactors directly or fire an SSR into a heating element without an interposing relay. The LCD display shows three rows of four characters each, with tri-color backlighting — you can assign the color to change on alarm or process status, which is a quick visual cue on a panel with multiple controllers. Panel cutout is 92.00 mm × 45.00 mm, the standard 1/16 DIN footprint. The IP66 front-panel rating means the face seals against washdown spray and dust ingress — suitable for food-processing or washdown zones where a standard IP54 controller would fail. Screw-terminal connections on the rear — no spring-cage option, so factor in the extra torque time during panel build-out.","metaTitle":"Omron E5EC-QR4D5M-000 Temperature Controller, 24VAC/DC, PID","metaDescription":"Omron E5EC-QR4D5M-000 process controller accepts RTD, TC, mA, VDC inputs. 24VAC/DC supply, relay + SSR voltage outputs, IP66 front.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Process / Temperature Controllers"],"specifications":{"Type":"Process, Temperature Controller (RTD, Type B, E, J, K, L, N, PLII, R, S, T, U, W)","Series":"E5EC","Weight":"0.463 lb (210.01 g)","Package":"Box","Input Range":"-200°C ~ 2300°C, 0 ~ 20mA, 0 ~ 10VDC","Output Type":"Relay (5), Voltage (External SSR)","Display Type":"LCD - Tri Color Characters, Backlight","Mounting Type":"Panel Mount","Control Method":"On/Off, Proportional (PID)","lifecycle_stage":"current","Voltage - Supply":"24VAC/DC","Termination Style":"Screw Terminal","Ingress Protection":"IP66 - Dust Tight, Water Resistant","Operating Temperature":"-10°C~55°C","Panel Cutout Dimensions":"Rectangular - 92.00mm x 45.00mm","Display Characters - Height":"0.710\" (18.00mm), 0.433\" (11.00mm), 0.307\" (7.80mm)","Number of Characters Per Row":"4, 4, 4"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/c6d2565f7c49acd020a74c22dc4212b3.pdf","sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/E5EC-QR4D5M-000/alternatives.json"},"ai":{"faq":[{"question":"What is the input power requirement for E5EC-QR4D5M-000?","answer":"The E5EC-QR4D5M-000 requires a 24VAC/DC supply — single-source, no separate control transformer needed if your panel already runs 24 V."},{"question":"Does Omron E5EC-QR4D5M-000 support Modbus communication?","answer":"This base model does not include a communications port; it has no RS-485 or Modbus interface.
