Status And Control In One Package
Current Switches with Relay:
Adjustable Trip Point, High
Voltage Output
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 flexibility.
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
FEATURES
● Combines command relay & fan/pump status sensor in a single, easy to
install unit
● Reduces number of components installed...fits better in small starter enclosures
● Command relay and status in a single unit
●
Easier to install than differential 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 different
configurations...added flexibility
● 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...fits many applications
● 5-year warranty

DETECTS BELT LOSS/COUPLING SHEAR! DETECTS BELT LOSS/COUPLING SHEAR!
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.
