It handles RTD, thermocouple types B, E, J, K, L, N, PLII, R, S, T, U, W, plus 0-20mA and 0-10VDC process signals. The IP66 front-panel rating means the display and keypad survive washdown splashes and dusty environments without a secondary cover. ## Four relays and PID — what you actually get Four relay outputs let you drive a heat/cool pair plus an alarm and a remote setpoint or event output from one controller — that's one fewer box on the panel door. The control method includes both on/off and full PID with auto-tune, so it works for simple tank heaters and for processes that need tight overshoot control. RS-485 with CompoWay/F and Modbus protocols means it talks to most PLCs and SCADA systems without a protocol converter. ## Active production — no obsolescence worry It ships in a standard box package with screw-terminal connections — no special tooling or mating connectors needed.","metaTitle":"Omron E5CC-RX3D5M-003 Process/Temp Controller, 4 Relay, 24V","metaDescription":"Omron E5CC-RX3D5M-003 process/temperature controller with 4 relay outputs, RS-485 Modbus, universal input, 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 (4)","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-RX3D5M-003/alternatives.json"},"ai":{"faq":[{"question":"Does the E5CC-RX3D5M-003 have 4 relay outputs?","answer":"Yes, the E5CC-RX3D5M-003 has four relay outputs, which is the maximum relay count in the E5CC series."},{"question":"What input types does the E5CC-RX3D5M-003 support?","answer":"It supports RTD, thermocouple types B, E, J, K, L, N, PLII, R, S, T, U, W, plus 0-20mA and 0-10VDC process inputs."},{"question":"Is the E5CC-RX3D5M-003 compatible with type K thermocouples?","answer":"Yes, type K is among the supported thermocouple types."},{"question":"Can the E5CC-RX3D5M-003 be used for PID control?","answer":"Yes, it supports on/off and proportional (PID) control methods."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/omron/E5CC-RX3D5M-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-RX3D5M-003 when reusing this data.
