It runs on a 24 VAC/DC supply, which is common in control panels where a 24 VDC bus is already present for PLCs and sensors — no need to pull a separate 100–240 VAC feed. The output stage gives you four relay contacts plus a voltage pulse for driving an external SSR. That combination covers both on/off and PID control of resistive heaters, solenoid valves, or contactor coils, while the SSR drive handles fast-cycle loads like a solid-state relay on an electric heater bank. ## Heater fault detection and event input onboard Built-in heater fault detection monitors the load current via an external CT and flags a broken heater or SSR short before the process drifts. The event input lets a PLC or limit switch remotely switch the controller between two setpoints or start/stop control — useful for recipe changeovers or interlocking with a safety circuit. The tri-color LCD backlight shows the PV, SV, and status characters in three rows (18 mm, 11 mm, and 7.8 mm high). The IP66-rated front panel withstands washdown in food or chemical processing environments — the gasket seals the bezel, not just the display window. ## Panel cutout and mounting The rectangular cutout is 92.00 mm × 45.00 mm — the standard 1/4 DIN footprint. Screw-terminal connections on the rear accept up to 14 AWG; no special crimp tooling needed.","metaTitle":"Omron E5EC-TQX4D5M-019 Process Controller, 24VAC/DC","metaDescription":"Omron E5EC-TQX4D5M-019 process/temperature controller. 24VAC/DC supply, 4 relay + voltage (SSR) outputs, universal input for TC/RTD/analog.","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)","Display Type":"LCD - Tri Color Characters, Backlight","Mounting Type":"Panel Mount","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-TQX4D5M-019/alternatives.json"},"ai":{"faq":[{"question":"What is the power supply requirement for the Omron E5EC-TQX4D5M-019?","answer":"It requires 24 VAC/DC.

It monitors the load current through an external current transformer and triggers an alarm on heater break or SSR failure."},{"question":"What is the panel cutout size for the E5EC-TQX4D5M-019?","answer":"The panel cutout is rectangular, 92.00 mm × 45.00 mm — the standard 1/4 DIN size.

The output count differs — six relays versus the four relays plus SSR drive on this unit. If serial comms are not needed and your panel already has 24 VDC, this is the cleaner fit."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/omron/E5EC-TQX4D5M-019","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-TQX4D5M-019 when reusing this data.
