TM
Detect belt loss
Cost-effectively monitor start/stop,
unit vents, fan coils,
exhaust fans, and other loads
where belt loss is not a concern
SPDT command
relay
H740 and H940 feature a SPDT
command relay
No tubing
necessary
Easier to install than differential
pressure switches
Easy setup
No calibration required…easy
setup and operation
APPLICATIONS
Maximize Reliability
The Hawkeye Relay Combination Series combines an on/off status
sensor and command relay in one package, saving the labor, wire runs,
and space required to mount a separate relay. The switch and relay
(not electrically connected) are in the same housing, saving space and
cost. It is ideal for monitoring and controlling motors where belt loss is
not a concern.
