The Therma SP panel thermometer selector switch units are housed in a standard DIN case (48 x 96mm). The panel thermometer selector switches may be used to extend the measurement capabilities of the Therma D81 and D85 panel thermometers, allowing either up to four or up to eight 2 or 3-wire PT100/RTD sensors to be coupled to a single panel thermometer.

All connections are made via rear plug and socket screw terminals. Each panel thermometer selector switch is supplied with one metre of PVC cable.
