Relay Controller

The Relay Controller provides a simple and low cost means of monitoring ABM’s radar and ultrasonic level sensors and controlling pumps and alarms according to the level measured.

  • Pump control and alarms applications
  • Connects with ABM level sensors via 4-20 mA output
  • Wall mountable for convenient measurement readout
  • Three (3) or six (6) relay options
  • Simple push-button programming
  • Robust NEMA 4X, IP65 enclosure

The Relay Controller from ABM provides a simple and low cost means of monitoring radar and ultrasonic level measurement devices and controlling pumps and alarms according to the level measured. The controller has one input to measure 4-20mA current from a level transducer and provide 24VDC to a level device. Current is displayed as a percentage. There are two settings: 4mA=100% and 20mA=0% or 4mA=0% and 20mA=100%. The setting is made with a movable link on the circuit board. The controller has the option of three (3) or six (6) relays as required for the application, which can be set to control pumps or alarms. The transducer current and set points, which are programmed into the controller, independently, for each relay control the relay operations.
