H932
Split-Core Current Transducer with Relay,
0-5 VDC Output
Product Overview
The H932 is a current-sensitive device that monitors current (amperage) in any of three field-selectable ranges;
0-30, 0-60, or 0-120 amperes. These ranges represent the maximum current that can be applied to the monitored
conductor. The H932 transforms the monitored current into a 0-5 VDC output suitable for connection to building
controllers or other appropriate data acquisition equipment. It is also equipped with a command relay.

•
•
Follow safe electrical work practices. See NFPA 70E in the USA, or applicable local codes.
This equipment must only be installed and serviced by qualified electrical personnel.
Read, understand and follow the instructions before installing this product.
Turn off all power supplying equipment before working on or inside the equipment.
Use a properly rated voltage sensing device to confirm power is off.
DO NOT DEPEND ON THIS PRODUCT FOR VOLTAGE INDICATION
• Only install this product on insulated conductors.
The H932 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.

Disconnect and lock out power to the enclosure containing the conductor to be
monitored.
Installation
CONTROLLER
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
wiring to reach the mounting location.
2. Drill holes to mount the bracket to the chosen surface using the
included screws.

POWER
CONTACTOR
3. Set the desired amperage range (30, 60, or 120 Amps).
4. Wire the output connections between the sensor and the
controller (0-5 VDC).
Fan or Pump
5. Snap the sensor over the wire to be monitored and clip the
assembly to the mounting bracket.
Motor
6. Scale the controller software to match the sensor’s output.
7. Secure the enclosure and reconnect power.
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.
240A
>120 A (sensor max.)
300A:5A
4A
H68xx-5A CT
DANGER: 5A CTs can present
hazardous voltages. Install
CTs in accordance with
manufacturer's instructions.
Terminate the CT secondary
before applying current.
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).
< 1.5 A (Sensor Min.)
1A
4x
CAUTION
RISK OF EQUIPMENT DAMAGE
• Derate the product’s maximum current for the number of turns
through the sensing 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
• Failure to follow these instructions can result in overheating
and permanent equipment damage.
