    The SSW72 series SMART temperature switches are microprocessor based instruments with an ON/OFF output signal. They can be remotely configured by a universal hand held terminal (HHT) or by a PC with a dedicated interface. Moreover, it is possible to locally configure the instruments (set threshold) by means of 2 pushbuttons and to display the current measured temperature on the display.



    The SSW72 switches are able to accept 3 wires PT100 ohm resistance thermometers and total accuracy is depending on class of the sensors utilized such as DIN A, DIN B, 1/3 DIN, 1/5 DIN,1/10 DIN.
    Based on these readings the microprocessor generates a standard ON/OFF signal output, shows the measurement on the display and command a contact depending by a set threshold.
