Veris H740 Current Switch


  • On/off status and command relay in a single labor and space-saving device
  • Detect belt loss – cost-effectively monitor start/stop, unit vents, fan coils, exhaust fans, and other loads where belt loss is not a concern
  • Easy setup – no calibration required easy setup and operation
  • SPDT command relay
  • No tubing necessary – easier to install than differential pressure switches
  • Induced from monitored conductor sensor power

Veris Industries is an energy and environmental sensor partner that provides quality products for commercial HVAC and other automation applications. We offer complete lines of reliable, long-lasting innovative power monitoring products.

The Hawkeye H740 combines an on/off status sensor and command relay in one package, saving the labor, wire runs, and space required to mount a separate relay. The switch and relay (not electrically connected) are in the same housing, saving space and cost. It is ideal for monitoring and controlling motors where belt loss is not a concern.
