Duplex Controller/Alternator

The CB2D/CMC15 is a dual stage controller with high & low level alarm used for control of applications requiring two control stage/points.

The CB2D/CMC15 is a dual stage controller with high & low level alarm used for control of applications requiring two control stage/points including, sewage or storm water pump stations, transfer pump stations, booster pump stations, and raw water/well pump stations.  The controller uses low cost and highly reliable discrete float or pressure switches as inputs and provides dry contact closure outputs for interface with up to 2 motor starter pilot circuits and high/low level alarm annunciation circuitry.

Features and Benefits

  • Independent turn-ON, common turn-OFF pump control.
  • Low alarm meets state codes requiring both high and low alarm in sewage lift stations.
  • Solid-state automatic pump alternation.
  • Can be configured to control a third (non-alternated) pump in place of high alarm.
  • Built to UL Industrial Control Panel standards.
  • Reliable, complete, compact, cost-effective and time-proven.
