Status And Control In
One Package
DESCRIPTION
The Hawkeye 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.
APPLICATIONS
●
Starting/stopping and monitoring positive status of motors
●
Detecting belt loss and coupling shear
FEATURES
●
Combines command relay and fan/pump status sensor in a single, easy to install
unit
●
Reduces number of components installed...fits better in small starter enclosures
●
Detect belt loss and motor failure...ideal for fan and pump status
●
H748 and H948 feature a SPDT command relay...control two outputs with a
single relay
●
Bracket on H938, H948, and H958 can be installed in three different
configurations...added flexibility
●
Reduced charges from electrician
●
Relay and status LEDs for easy setup
●
Polarity insensitive status output...fast and easy installation
●
Adjustable setpoint 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.
