Veris H721HC Current Transducer


  • Power the sensor, and receive the signal with only 2-wires, lower cabling and commissioning costs than with traditional 3-wire sensors
  • Economical solid-core features adjustable bracket for easy alignment
  • Factory calibrated switch-selectable ranges for high resolution and installation ease
  • Three field-selectable ranges per unit, fewer versions to choose from, stock, and install
  • Removable mounting bracket for installation flexibility
  • 100% solid-state no moving parts to fail
  • 30 mA at 12 to 30 VDC 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.

Hawkeye Relay Combination Series high voltage output current switches are the ideal solution for the automation installer. These units combine a current switch and relay into a single package, reducing the space required for total control of fans and pumps. The integrated current switch and relay operate independently of one another. All relay connections are externally available for maximum flexibility. These products perform the functions of start/stop and status monitoring with one device instead of two.

The Hawkeye H721HC provides accurate load trending information with a proportional 4 to 20 mA output signal. Preset slide switches provide easy field setup of sensed amperage range with no need for jumpers.
