It drives up to five relay outputs for on/off or PID control, and communicates over RS-485 using either CompoWay/F or Modbus protocols. The 24 VAC/DC supply keeps the controller on the same control transformer as the PLC and field I/O — no separate 100–240 VAC tap needed. The five relay outputs are rated for direct switching of contactors, solenoid valves, or alarm loads up to the relay contact rating; for driving an external SSR, the sibling E5EC-QR4D5M-009 adds a dedicated voltage pulse output alongside the relays. IP66 on the front panel means the controller face withstands washdown spray and dust ingress — suitable for food, beverage, or chemical process panels where the enclosure is hosed down. The rectangular 92.00 mm x 45.00 mm cutout is the standard 1/4 DIN footprint; the screw terminals accept solid or stranded wire without a special tool. The tri-color LCD backlight shows three rows of four characters each, with the top row at 18.00 mm height for the process variable — readable from across a machine cell. Heater fault detection monitors current via an external CT and flags a broken heater element, a common failure in electric heat zones.","metaTitle":"Omron E5EC-RX4D5M-009 Process Temperature Controller","metaDescription":"Omron E5EC-RX4D5M-009 process/temperature controller with 5 relay outputs, RS-485 Modbus, universal input, 24 VAC/DC supply, 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, Heater Fault Detection","Input Range":"-200°C ~ 2300°C, 0 ~ 20mA, 0 ~ 10VDC","Output Type":"Relay (5)","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-RX4D5M-009/alternatives.json"},"ai":{"faq":[{"question":"Does the E5EC-RX4D5M-009 support Modbus?","answer":"Yes.
