Veris H938 Current Switch


  • Combined relay and status – combines command relay and fan/pump status sensor in a single, easy-to-install unit
  • Fan and pump status – detect belt loss and motor failure ideal for fan and pump status
  • Polarity insensitive status outputs – fast and easy installation
  • Two outputs – H948 feature an SPDT command relay control two outputs with a single relay
  • Added flexibility – bracket on H938 can be installed in three different configurations
  • Easy setup – relay and status LEDs
  • 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 H938 relay combination series is 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 current switch and relay operate independently of one another. These devices allow start/stop control and status monitoring with one device instead of two.
