Product Overview
The H908 is a current-sensitive switching device that monitors current (amperage) in the conductor passing
through it. A change in amperage in the monitored conductor that crosses the switch (setpoint) threshold plus the
hysteresis value causes the resistance of the FET status output to change state, similar to the action of a mechanical
switch. In this model, the setpoint is adjustable through the action of a twenty (20) turn potentiometer (see the
CALIBRATION section). The status output is suitable for connection to building controllers or other appropriate data
acquisition equipment operating at up to 30 volts. The H908 requires no external power supply to generate its
output.
The H908 housing offers unprecedented mounting flexibility. The mounting bracket can be attached in three
different places. Additionally, the bracket is compatible with the Veris AH01 DIN Rail clip, allowing DIN mounting.
