H739 SERIES & H939 SERIES
VERIS INDUSTRIES
Current Switches with Relay: Adjustable Trip Point, High Voltage Output
Status And Control In One Package
DESCRIPTION
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 exibility.
These products perform the functions of start/stop and status monitoring with one device instead of two.
APPLICATIONS
Starting/stopping and monitoring positive status of motors
Detecting belt loss and coupling shear
current monitoring

Now you can easily detect when drive belts slip, break, or pump couplings shear. In fact, a typical HVAC motor that loses its load has a reduction of current draw of up to 50%. That’s why our sensors are the industry standard for status.

FEATURES
Combines command relay & fan/pump status sensor in a single, easy to
install unit
Reduces number of components installed...ts bet ter in small starter enclosures
Command relay and status in a single unit
Easier to install than dierential pressure switches...no additional wiring
needed
Detect belt loss and motor failure...ideal for fan and pump status
Bracket on H939, H949, and H959 can be installed in three dierent
congurations...added exibility
H749 and H949 feature SPDT command relay...saves installation time
Reduced charges from electrician
Relay and status LEDs for easy setup
Polarity insensitive status output...fast trouble-free installation
Adjustable trip point for current sensor status...ts many applications
