It runs on a 24 VAC/DC supply — common in industrial panels where a single 24 VDC bus powers both the controller and downstream logic — and delivers control via five relay outputs plus a voltage pulse for an external SSR. The control method is selectable between simple On/Off and full Proportional (PID) with auto-tuning, so it handles everything from a resistive oven to a fast-responding injection mold zone. The IP66-rated front panel means the electronics are sealed against washdown spray and dust ingress — a requirement for food-processing or pharmaceutical environments where the panel face gets hosed down. Panel cutout is 92.00 mm x 45.00 mm. Termination is via screw terminals, so field wiring with ferruled stranded or solid conductors is straightforward; no special crimp tool needed. ## Lifecycle and sourcing note","metaTitle":"Omron E5EC-QR4D5M-011 Temperature Controller, 24VAC/DC, PID","metaDescription":"Omron E5EC-QR4D5M-011 process temperature controller. 24VAC/DC supply, relay & voltage outputs, PID control, IP66 front panel.
