That -200°C to 2300°C span covers cryogenic chambers right up to furnace thermocouples. Three relay outputs handle on/off or alarm functions, and the voltage pulse output drives an external SSR directly for PID control — no extra interposing relay needed between the controller and the heater contactor. ## Modbus RTU and the heater fault check RS-485 communication with both CompoWay/F and Modbus protocol means this controller talks to any PLC or SCADA that speaks Modbus RTU — no proprietary gateway required. The 100-240 VAC supply range lets it run on whatever line voltage your panel already carries. 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. For a small shop running a single oven or extruder barrel, that one feature can save a batch before you even know there's a problem. The IP66 front face handles washdown splashes and dusty control cabinets; the screw terminals are accessible without pulling the controller from the panel. Dual-line LCD shows process value (0.600\" digits) and setpoint (0.280\" digits) simultaneously — four characters each row, so you see PV and SP at a glance without scrolling.","metaTitle":"Omron E5CC-TQX3A5M-003 Temperature Controller, PID, Modbus","metaDescription":"Omron E5CC-TQX3A5M-003 Process/Temperature Controller.

The RS-485 port supports both Omron CompoWay/F and standard Modbus RTU protocol, so it connects directly to any PLC or HMI that speaks Modbus. No extra converter needed."},{"question":"What is the difference between E5CC-TQX3A5M-003 and E5CC-QX3A5M?","answer":"The -TQX3A5M-003 adds heater fault detection and a third relay output compared to the base E5CC-QX3A5M. Both share the same 45 mm cutout, universal input, and Modbus RS-485. If you are monitoring heater current on an oven or extruder, the -T variant saves adding a separate current monitor."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/omron/E5CC-TQX3A5M-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-TQX3A5M-003 when reusing this data.
