E5AN-R3MT-500-N

The E5AN-R3MT-500-N is a basic-type digital temperature controller from the reliable E5AN Series, designed for industrial environments that require consistent temperature control, improved accuracy, and easy maintenance. With a 1/4 DIN (96 × 96 mm) panel-mount size and a wide-range 100–240 VAC power supply, this controller has been widely used in automation panels and process control systems.

This model is equipped with a relay control output, making it suitable for direct control of heaters, contactors, and other switching devices. It supports a universal input, allowing connection to both thermocouples and Pt100 resistance temperature detectors, providing flexibility across various applications. The inclusion of three auxiliary outputs enables alarm signaling, interlocks, and status monitoring.

The E5AN-R3MT-500-N offers improved indication accuracy over older-generation controllers and includes preventive maintenance functionality by monitoring control output ON/OFF counts. A one-touch PF (Function) key simplifies operation, while the supplied packing seal allows the controller to achieve IP66 protection when properly installed. Although this model is now obsolete and no longer manufactured, it remains relevant for legacy system support and replacement needs.
