The Hawkeye 931 provides accurate load trending information with
a proportional 4 to 20 mA output signal. These devices offer three
amperage ranges for versatility, with easy slide-switch selection. The
command relay is fully integrated in the device, but it is isolated from
the current transducer. This combination makes these products ideal
for start/stop control and status monitoring of motors, using one device
instead of two.
