The general purpose AC or DC powered level controller displays engineering units with one 4-20 mA level transmitter input and is offered in three configurations with optional 2 or 4 programmable relays, and an isolated 4-20 mA repeater. Each relay can be configured on a single set point (high level alarm or low level alarm) or latched on two set points for automatic fill or empty in simplex (one pump or valve) or duplex (two pumps) level control modes.


  • LED main display and secondary unit display with relay status
  • Easy configuration via the push button display module
  • DIN enclosure with NEMA 4X faceplate and shallow case
  • Isolated power supply to sensor with optional 4-20 mA repeater
  • Non-volatile memory with security password protection
  • 32-point linearization function for volumetric measurement
