Screw-terminal connections are used. The front bezel is IP66-rated. ## What the outputs and inputs actually do Three relay outputs drive the primary control loop, alarm, or event functions — rated for switching contactors, solenoid valves, or indicator loads directly. Two additional voltage pulse outputs (for external SSRs) handle fast-cycle heater or cooling loads where relay life would be a concern. The universal input accepts RTD (Pt100, JPt100) and twelve thermocouple types (B, E, J, K, L, N, PLII, R, S, T, U, W) covering -200°C to 2300°C, plus 0-20 mA or 0-10 VDC linear process signals. That means one part number covers the sensor types you'd find on a plastics extruder, a packaging sealer, or a heat-treatment furnace — no variant swap needed. The heater fault detection feature monitors current draw on the load side and flags a broken heater or SSR short before the process drifts out of tolerance — a practical diagnostic for electric ovens and hot-runner systems where an undetected open element means scrap parts. ## Control and communications On/off or PID control method is selectable per loop. The RS-485 port speaks both Omron CompoWay/F and Modbus RTU.","metaTitle":"Omron E5CC-QQ3D5M-003 Temperature Controller, 24VAC/DC","metaDescription":"Omron E5CC-QQ3D5M-003 process/temperature controller. 24VAC/DC supply, RS-485 Modbus RTU, relay + SSR outputs, IP66 front panel.","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":"E5CC","Weight":"0.265 lb (120.2 g)","Package":"Box","Features":"Heater Fault Detection","Input Range":"-200°C ~ 2300°C, 0 ~ 20mA, 0 ~ 10VDC","Output Type":"Relay (3), Voltage (External SSR) (2)","Display Type":"LCD - Dual 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":"Square - 45.00mm x 45.00mm","Display Characters - Height":"0.600\" (15.20mm), 0.280\" (7.10mm)","Number of Characters Per Row":"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/E5CC-QQ3D5M-003/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/omron/E5CC-QQ3D5M-003","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/E5CC-QQ3D5M-003 when reusing this data.
