Screw terminals on the back mean you can land field wiring without a crimper or special tool — handy when the panel is already wired and you're just swapping the controller. The IP66 front panel rating means it handles washdown spray from the front — good for food, beverage, or any line where hoses come out at the end of shift. ## What it controls and how it connects It reads thermocouple types B, E, J, K, L, N, PLII, R, S, T, U, W, plus RTD, and also accepts 0-20 mA or 0-10 VDC analog signals — so it covers both temperature and linear process inputs in one unit. Control method is PID or On/Off — PID for tight thermal loops (oven, extruder, injection mold), On/Off for simple limit or alarm functions. Outputs are mixed: two analog channels for driving SCRs or valve positioners, plus four relay outputs for on/off control, alarms, or event sequencing. The event input lets an external dry contact trigger a ramp/soak hold, alarm reset, or setpoint change without touching the front panel — useful for tying into a safety interlock or remote E-stop circuit. ## Fieldbus and BOM-fit note RS-485 with CompoWay/F and Modbus protocols — hooks into a PLC or SCADA network for setpoint download, PV readback, and alarm acknowledgment over the same two wires. Supply voltage is 24 VAC/DC — common on most control panels; no separate 100-240 VAC power supply needed if your panel already runs 24 V. Operating temperature range -10°C to 55°C — fine for indoor electrical rooms and most production-floor enclosures, but don't mount it in an unheated outdoor cabinet in a northern winter. The closest functional sibling in the E5EC family is the E5EC-QR4D5M-010, which trades the two analog outputs for a voltage (SSR drive) output plus heater fault detection. If your application uses external SSRs instead of analog SCRs, that variant may save a wiring point.","metaTitle":"Omron E5EC-CC4D5M-004 Process Controller, 24V, PID, RS-485","metaDescription":"Omron E5EC-CC4D5M-004 process/temperature controller, 24VAC/DC, PID control, RS-485 Modbus, 2 analog + 4 relay 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","Features":"Event Input","Input Range":"-200°C ~ 2300°C, 0 ~ 20mA, 0 ~ 10VDC","Output Type":"Analog (2), 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":"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-CC4D5M-004/alternatives.json"},"ai":{"faq":[{"question":"Will E5EC-CC4D5M-004 drop into a panel cut for E5EC-QR4D5M-010 without rewiring?","answer":"Yes — both use the same 92x45 mm rectangular panel cutout and screw terminals. The wiring difference is on the output side: the CC4D5M-004 has two analog outputs plus four relays, while the QR4D5M-010 has five relays plus a voltage (SSR) output. If your existing wiring lands on the relay terminals, it maps directly; the analog outputs on the CC4D5M-004 occupy the same screw positions as the SSR drive on the QR4D5M-010, so check the terminal assignment in the manual before powering up."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/omron/E5EC-CC4D5M-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-CC4D5M-004 when reusing this data.
