Two voltage outputs drive external SSRs for PID-controlled heating zones where the cycle rate would wear out mechanical contacts. The 24VAC/DC supply rail means this controller runs off the same control transformer that powers PLCs and sensors in a typical panel — no separate 100-240VAC tap needed. ## Sensor and input flexibility Accepts RTD, thermocouple types B/E/J/K/L/N/PLII/R/S/T/U/W, plus 0-20mA or 0-10VDC linear process signals. That covers the full range from cryogenic RTD to 2300°C high-temp furnace work on one SKU. The heater fault detection feature monitors current draw on the load side and flags a broken heater or SSR short — a common failure mode in electric ovens and extruder barrel heaters that otherwise goes unnoticed until product quality drifts. ## Panel fit and environmental sealing Panel cutout is 92mm x 45mm, the standard 1/4 DIN horizontal footprint. Screw terminals on the rear — no special crimp tooling needed for field wiring. IP66 front panel rating means the display and keypad survive washdown spray. The gasket seals against the panel face, not the enclosure door — useful for food processing or outdoor cabinet installations where a hose-down is part of the sanitation cycle. ## Communication and lifecycle RS-485 port supports both Omron CompoWay/F and Modbus RTU. That lets a PLC or SCADA system read PV, setpoint, and alarm status without extra analog I/O cards.","metaTitle":"Omron E5EC-TQQ4D5M-008 Process Controller, 24VAC/DC","metaDescription":"Omron E5EC-TQQ4D5M-008 E5EC-T series process controller. 24VAC/DC supply, 4 relay + 2 voltage (SSR) 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-T","Weight":"0.463 lb (210.01 g)","Package":"Bulk","Features":"Event Input, Heater Fault Detection","Input Range":"-200°C ~ 2300°C, 0 ~ 20mA, 0 ~ 10VDC","Output Type":"Relay (4), Voltage (External SSR) (2)","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-TQQ4D5M-008/alternatives.json"},"ai":{"faq":[{"question":"Will the E5EC-TQQ4D5M-008 drop into a panel cut for the E5EC-TRR4A5M-008 without rewiring?","answer":"Mechanically yes — both use the same 92mm x 45mm panel cutout and screw terminals. Electrically the difference is the supply voltage: the TQQ4D5M-008 runs on 24VAC/DC, while the TRR4A5M-008 requires 100-240VAC. The output configuration also differs — this unit has 4 relay + 2 voltage (SSR) outputs versus 6 relay outputs on the TRR4A5M-008. If your application uses SSR-driven outputs, this is the closer match; if you need six discrete relay outputs, the TRR4A5M-008 is the better fit."},{"question":"What is the E5EC-TQQ4D5M-008 used for?","answer":"It is a process and temperature controller accepting RTD, thermocouple, or linear analog inputs. Typical applications include industrial oven control, plastic extruder barrel heating, packaging machine heat-seal stations, and HVAC duct temperature regulation. The heater fault detection feature makes it particularly suited for electric heating loads where element failure must be caught early."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/omron/E5EC-TQQ4D5M-008","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-TQQ4D5M-008 when reusing this data.
