ELKO EP TER-4 Double Thermostat

ELKO EP TER-4 Double Thermostat comes with a temperature range of -40°C to +110°C and is designed for temperature monitoring and regulation over a widerange. This device includes rough and fine temperature settings for each thermostat and provides a selection of heating/cooling functions. The TER-4 double thermostat features a 24V to 240V AC/DC galvanically isolated power supply and a maximum power dissipation of 2.4W. This double thermostat offers 2x input for temperature sensor NTC 12k/25°C and selectable hysteresis (sensitivity) of switching. Additional features include setting the thermostat's independent or dependent function and two output contacts (one for each thermostat). This double thermostat is available with a DIN rail EN 60715 mounting and provides IP40 front panel/IP20 terminal protection degrees. The TER-4 double thermostat is used for temperature monitoring in switchboards, heating or cooling systems, engines, liquids, and open spaces.
