Product Overview
The H906 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 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 H906 requires a 5 to 30 Vdc external power supply to generate its
output.
The H906 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.

H906 Installation Guide
Disconnect and lock out power to the enclosure containing the conductor to be
monitored.
1. Locate a mounting surface for the removable mounting
bracket that will allow the monitored conductor to pass
through the center window when it is installed and that will
keep the product at least ½” (13 mm) from any uninsulated
conductors. Determine cable routing for the controller
connection, allowing the wiring to reach the mounting
location.
2. Drill holes to mount the bracket to the chosen surface using
the included screws.
3. Wire the output connections from the sensor to the controller
(solid-state contact) and to the external power supply.
Observe polarity.
4. Snap the sensor over the conductor and clip the assembly to
the mounting bracket.
5. Secure the enclosure and reconnect power.
6. Calibrate the sensor with the load running normally.

H906 Installation Guide
Notes For load currents greater than sensor maximum rating:
Use a 5 Amp (H68xx series) current transformer (CT) as shown. This technique can be combined with wrapping (see below) to add
range for a low current load on a high current source.
DANGER: 5A CTs can present
hazardous voltages. Install
CTs in accordance with
manufacturer's instructions.
Terminate the CT secondary
before applying current.
NOTICE
RISK OF EQUIPMENT DAMAGE
• Derate the product’s maximum current for the number of turns
through the current sensor window using the following formula:
Rated Max. Amps ÷ Number of Turns = Max. monitored Amps
e.g. : 100A ÷ 4 Turns = 25 Amps max. in monitored conductor
• Never exceed the current sensor rating.
• Failure to follow these instructions can result in overheating
and permanent equipment damage.

For load currents less than sensor minimum rating:
Wrap the monitored conductor through the center window and around the sensor body to produce multiple turns. This increases
the current measured by the transducer. Program the controller to account for the extra turns (e.g., if four turns pass through the
sensor (as shown) divide the normal reading by 4).

Calibration
Troubleshooting Problem Solution
No reading at controller • Check sensor calibration (see above)
• Check for control voltage at sensor (5Vdc < voltage < 30 V)
• Check for amperage in monitored conductor (> 2.5 A)
• Verify correct polarity
• Assure that sensor core mating surfaces are clean and that the core clamp is completely closed
Setpoint screw has no stops The setpoint screw has a slip-clutch at both ends of its travel to avoid damage.Twenty turns CCW will
reset the sensor to be most sensitive. Repeat calibration above.
Both LEDs are lit Setpoint screw is too far clockwise. See solution above.
