Product details

Panel fit and input flexibility

The Omron E5CC-QX3D5M-003 is a 1/16 DIN process and temperature controller that accepts RTD, thermocouple types B/E/J/K/L/N/PLII/R/S/T/U/W, plus 0-20mA or 0-10VDC analog signals, covering a span from -200°C to 2300°C. 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.

Frequently asked questions

Does E5CC-QX3D5M-003 support Modbus RTU?

Yes. 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.

What is the difference between E5CC-QX3D5M-003 and E5CC-QX2DBM-002?

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.
