The 45mm square panel cutout matches the standard E5CC footprint, and the IP66-rated front bezel handles washdown splashes in food or chemical environments. ## Outputs and communications for machine integration Three relay outputs handle on/off or alarm duties, and a voltage pulse output drives an external SSR for PID-controlled heating. The RS-485 port speaks Modbus RTU or CompoWay/F, so the controller drops into a PLC-based line without a separate gateway. Power is 24VAC/DC, common in cabinet supplies. ## Heater fault detection saves line-down diagnostics Built-in heater fault detection monitors the load current via an external CT (not included) and flags a broken heater or SSR short before the process drifts. On a plastic-injection or packaging line, that alarm can trigger a PLC interrupt instead of waiting for a temperature deviation to shut the line.","metaTitle":"Omron E5CC-QX3D5M-003 Temperature Controller, 24VAC/DC","metaDescription":"Omron E5CC-QX3D5M-003 process/temperature controller.

The RS-485 port supports both Modbus RTU and Omron's CompoWay/F protocol. This lets the controller communicate directly with a PLC or SCADA system over the same two-wire bus."},{"question":"What is the difference between E5CC-QX3D5M-003 and E5CC-QX2DBM-002?","answer":"Both are E5CC-series controllers with the same input range, RS-485, and 24VAC/DC supply. The key difference is termination: the -003 uses screw terminals, while the -002 uses spring terminals. The -003 also has three relay outputs versus the -002's two relays."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/omron/E5CC-QX3D5M-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-QX3D5M-003 when reusing this data.
