FSST Tachometer Relays

The Tempatron FSST tachometer relays are designed to monitor and control speed by energising the relay output when the monitored speed exceeds the setting on the user adjustable front dial. The speed setting is adjustable from 200rpm to 10,000rpm and the relay has an internal 24Vdc power supply for powering active sensors, plus a 0-0.1mA meter output, with calibration adjustment, for displaying the speed. The tachometer relays are housed in a compact DIN48 square enclosure which can either panel mount or surface/DIN rail mount to a socket and they are auxiliary powered from either 110 or 230Vac. The 5 Amp rated single pole changeover relay output contact is isolated from the supply voltage and the relays have two LEDs to indicate both power and relay status.
