That input flexibility means one stock number covers most loop types in the plant, reducing spare-part count. The mixed output bank — four relay outputs plus two voltage pulse outputs for external SSRs — lets it drive contactors directly while simultaneously firing a solid-state power pack for fast-cycling heater zones. The relay side handles on/off or alarm duties; the SSR side handles the PID time-proportioned loop. ## RS-485 Modbus and heater fault detection RS-485 communications with both CompoWay/F and Modbus protocols are onboard — the controller appears as a standard Modbus RTU slave on the line, readable by any PLC or SCADA host without a gateway. The event input allows remote selection of a second setpoint or auto/manual transfer, useful for recipe changeovers. The heater fault detection feature monitors current draw on the load side and flags a broken heater element or failed SSR before the process drifts. This is a real time-saver on multi-zone ovens and extruder barrels where one dead zone can scrap a batch. ## Panel fit and environmental sealing Panel cutout is 92.00mm x 45.00mm (standard 1/4 DIN), with screw-terminal connections on the rear. The IP66-rated front panel — dust-tight and protected against hose-directed water — means it can be mounted on a washdown cabinet face or in a food-processing area without a separate cover. The tri-color LCD backlight (green, orange, red) lets operators see alarm conditions from across the floor — the display characters are 18.00mm, 11.00mm, and 7.80mm tall across four rows.","metaTitle":"Omron E5EC-TQQ4A5M-008 Temperature Controller, 100-240VAC","metaDescription":"Omron E5EC-TQQ4A5M-008 process/temperature controller. 100-240VAC supply, 4 relay + 2 SSR drive outputs, RS-485 Modbus, heater fault detection.","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":"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-TQQ4A5M-008/alternatives.json"},"ai":{"faq":[{"question":"Does the E5EC-TQQ4A5M-008 support Modbus RTU?","answer":"Yes — RS-485 with both CompoWay/F and Modbus protocols is built in.
