E5AN-Q3MT-500-N

The E5AN-Q3MT-500-N is a 1/4 DIN basic digital temperature controller from the proven E5AN Series, designed for industrial applications requiring stable control, accurate measurement, and SSR-driven outputs. Operating on a wide-range AC 100–240 V power supply, this model has been widely deployed in control panels across manufacturing environments.

This controller features a universal input supporting both thermocouples and platinum resistance thermometers, making it suitable for a wide variety of temperature sensing needs. The voltage control output is specifically designed for driving solid-state relays (SSR), ensuring reliable and fast switching performance. With three auxiliary outputs, the E5AN-Q3MT-500-N enables alarms, status signaling, and interlock control within complex automation systems.

Known for its improved indication accuracy and 3-level display, the controller allows simultaneous monitoring of process value (PV), set value (SV), and manipulated value (MV). Although this model is now considered obsolete/end-of-life, it remains in demand for maintenance, replacement, and legacy system support, and is often sourced through surplus or refurbishment channels.
