What this order code delivers
The Omron E5EC-QR2DSM-810 is a 1/8DIN panel-mount temperature controller from the E5EC family, configured with a voltage output for driving an external SSR and a relay output for on/off or alarm duty, plus heater burnout (HB) detection. The "M" in the suffix indicates the multi-input universal input type, accepting thermocouple, RTD, or analog signals. This is the active-production variant — no lifecycle concerns for new designs or MRO spares.
The 1/8DIN form factor (48 x 96 mm panel cutout) fits standard panel punch patterns — it replaces or upgrades an older 1/8DIN controller without re-cutting the panel. The relay output handles up to 3 A at 250 VAC resistive, suitable for driving a contactor coil, small heater contactor, or alarm indicator directly. The voltage pulse output (12 VDC, 40 mA typical) fires an external SSR for the main heating load, isolating the high-current switching from the controller itself. Heater burnout detection monitors current draw on the load side via an external CT (not included) and flags a broken heater or SSR short — a practical safeguard for electric furnaces, extruder barrels, and packaging seal bars where an undetected failed heater scrapes product or damages the process.
Mounts into a standard 1/8DIN panel cutout, retained by the included mounting bracket. Wiring is via screw terminals on the rear housing — thermocouple/RTD input, CT input for HB, voltage pulse to SSR, and relay output. The controller is self-powered (100–240 VAC) so no separate control transformer is needed for the logic supply.
