It drives loads through one analog output and four relay outputs, so you can send a retransmission signal to a recorder or PLC while switching heaters, alarms, or valves directly. The IP66-rated front panel holds up in washdown environments — food, beverage, or chemical lines where hose-down cleaning is routine. ## Communications and control RS-485 on screw terminals speaks both CompoWay/F and Modbus RTU, so it drops into existing Omron networks or any Modbus master without a gateway. Control method is On/Off or full PID with auto-tune — set it for a simple limit switch or dial in tight temperature regulation on an oven or extruder barrel. The tri-color LCD backlight shows four characters per row across three rows; the largest digits are 18mm high, readable from across a machine cell. ## Panel fit and supply Cutout is 92mm x 45mm rectangular — standard 1/4 DIN footprint, no adapter plate needed for existing panel holes.","metaTitle":"Omron E5EC-CX4A5M-004 Temperature Controller, 100-240VAC","metaDescription":"Omron E5EC-CX4A5M-004 process/temperature controller. 100-240VAC supply, analog + 4 relay outputs, RS-485 Modbus, 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","Features":"Event Input","Input Range":"-200°C ~ 2300°C, 0 ~ 20mA, 0 ~ 10VDC","Output Type":"Analog, Relay (4)","Display Type":"LCD - Tri Color Characters, Backlight","Mounting Type":"Panel Mount","Communications":"RS-485 (CompoWay/F, Modbus)","Control Method":"On/Off, Proportional (PID)","lifecycle_stage":"current","Voltage - Supply":"100 ~ 240VAC","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-CX4A5M-004/alternatives.json"},"ai":{"faq":[{"question":"What Modbus protocol does E5EC-CX4A5M-004 support?","answer":"RS-485 with both CompoWay/F (Omron's legacy protocol) and Modbus RTU, configurable via the front panel or software."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/omron/E5EC-CX4A5M-004","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/omron/E5EC-CX4A5M-004 when reusing this data.
