The EMKO ESM-3712-HCN is a versatile digital temperature controller designed for reliable temperature monitoring and control across refrigeration, heating, cooling and general industrial applications.
Available with a choice of NTC, PTC, Pt100, Pt1000 and J or K thermocouple inputs, the ESM-3712-HCN combines straightforward ON/OFF temperature control with a separate 5A rated alarm output, adjustable hysteresis and selectable heating or cooling operation.
With adjustable temperature offset, configurable alarm parameters and high/low set-point limits, the controller can be tailored to suit a wide variety of equipment and processes. A powerful 16A relay control output makes it particularly suitable for compressor and refrigeration applications, while the additional 5A alarm relay provides independent signalling when predetermined temperature conditions are reached.
Optional RS-485 Modbus RTU communication is also available for applications requiring remote monitoring, data collection or integration with wider control systems.
