Key Features

Can also be used with the Irritrol PC Control system for switching control of low voltage landscape lighting

Saves the expense of an extra timer and puts irrigation and landscape lighting control in one location on the owner’s computer

Electrical relays for both low voltage (24V ac) control switching and high voltage (120V ac or 240V ac) main power contacts

  • Allows remote pump switching using 24V ac output from an irrigation controller’s master valve/pump start circuit
  • Opens and closes main power contacts for pumps (1HP at 120V ac 1 Phase or 2HP at 250V ac 1 Phase)
  • - Note: 2HP at 120V ac will exceed maximum amp rating

Highly efficient 0.1 Amp operating requirement

Draws less holding power than most solenoid valves
