Five relay outputs handle on/off or alarm functions (e.g., high-temp trip, heater break alarm), while the dedicated voltage output drives an external SSR for PID-controlled heating — a common split for electric furnace zones where the SSR handles the switching duty cycle and the relays manage safety interlocks. The tri-color LCD backlight shows three rows of four characters each — the top row at 18 mm height is readable from several metres across a control panel, useful for operators scanning multiple loops. ## Panel fit and environmental sealing Panel mount with a 92 mm x 45 mm rectangular cutout — the standard 1/4 DIN footprint that drops into existing punched panels without rework. IP66 front-panel rating means the controller face is dust-tight and protected against hose-directed water — it survives washdown in food-and-beverage lines or outdoor cabinet installations where condensation is routine. Screw-terminal connections on the rear — no special crimp tooling needed; field wiring with ferrule or bare stranded wire is straightforward for panel builders and MRO techs. The controller ships as a starter kit that includes the controller, a configuration cable, and software — one order code covers the hardware and the programming toolchain, saving a separate cable-and-software buy for the first unit.","metaTitle":"Omron E5EC-QR4A5M-5800U Temperature Controller","metaDescription":"Omron E5EC-QR4A5M-5800U process/temperature controller.

The key difference is the output complement: the E5EC-QR4A5M-5800U has five relay outputs plus a voltage output for an external SSR, while the E5EC-CQ4A5M-011 has four relay outputs plus an analog output. If your application needs the fifth relay or the dedicated SSR voltage drive, the QR4A5M variant is the correct fit; otherwise the CQ4A5M can serve as a drop-in with the same wiring base."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/omron/E5EC-QR4A5M-5800U","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/E5EC-QR4A5M-5800U when reusing this data.
