E5EN-Q3MT-500-N

The Omron E5EN-Q3MT-500-N is a reliable digital temperature controller from the E5EN Series (Basic Type), designed for industrial temperature control applications that require stable PID performance and SSR-driven outputs. With its 1/8 DIN (48 × 96 mm) panel-mount form factor, this controller was widely used in automation panels across manufacturing and process industries.

This model supports universal temperature inputs, allowing connection to both thermocouples and resistance temperature detectors, providing flexibility across different processes. The voltage control output is intended for driving solid-state relays (SSR), ensuring fast and reliable switching. Equipped with three auxiliary outputs, it enables alarm signaling and interlock control to enhance system monitoring and safety.

The E5EN-Q3MT-500-N features a 3-level display, allowing simultaneous monitoring of key parameters such as process value and set value. Powered by a wide-range 100–240 VAC supply, it was engineered for continuous industrial operation. Although this model is now obsolete and no longer manufactured, it remains relevant for legacy system maintenance and replacement, with newer E5_C series controllers commonly recommended as substitutes.
