Maximize Reliability
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.

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.
