H970HCA

The H970HCA is a current-sensitive device that monitors DC current (amperage)

in the conductor passing through it. The unit combines a Hall Eﬀect sensor with

proven transducer circuitry, with a status output suitable for connection to building

controllers or other appropriate data acquisition equipment operating at up to

30 volts. The H970HCA requires 12-30VAC/DC to generate its output. Selectable

amperage ranges and output types maximize the installation ﬂexibility.

opEration

notEs

troublEshooting

sEt-up anD Wiring

For load currents less than sensor minimum rating:

Wrap the monitored conductor through the center hole and around the sensor body

to produce multiple turns through the "window." This increases the current measured

by the transducer.

Controller must be

programmed to account

for the extra turns. e.g., if

four turns pass through the

sensor (as shown) the normal

controller reading must be

divided by 4.

< 5A (sensor min.) 4x

Problem Solution

The LED is oﬀ and no signal is

produced

Verify that power is applied to PWR (+) and GND (-)

terminals

The LED is on solid and the output

is at maximum

Verify that the amperage range selection switch is

in the proper position for the current applied to the

conductor.
