DESCRIPTION
The Hawkeye 931 and 951 provide accurate load trending information with a
proportional 4-20mA output signal. These devices oer 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 sensor. This combination makes these
products ideal for start/stop control and status monitoring of motors, using one
device instead of two.
APPLICATIONS
● Load trending
● Motor control
● Positive proof of ow
current monitoring

FEATURES
● Loop-powered analog current sensor with integral start/stop command relay
● Reduces the number of installed components...saves time and space
● Self-gripping split-core for fast retrot installation...no need to remove
conductor
● One device to install for start/stop & status...reduces installation charges
● Power the current sensor and receive the 4-20mA signal with only two wires...
fewer wires required than with traditional 3-wire sensors
● Selectable factory calibrated ranges up to 120A for increased exibility and
resolution
● Factory calibrated switch-selec t able ranges (30/60/120A) for high resolution and
installation ea se
● No jumpers on unit...reduce installation error
● Removable mounting bracket for installation exibility
● Bracket can be installed in three dierent congurations...added exibility
● Command relay switches up to 5A@250VAC
● 5-year warranty
