RM34 temperature relay

  • 4 temperature ranges -50...+200ºC for PT100 sensor
  • Adjustable time delay
  • Kaksi lähtörelettä ja invertointimahdollisuus

Product description

RM34 relay is used for temperature metering. Features a Pt100 sensor (DIN43760) with 2 or 3 wires. You can select between 4 metering ranges. Relay activation, inversion and delay are adjusted by DIP switches in the bottom of the relay. Relay will release in the occasion of short-circuit or cable breakage.
