H221/H221SP

Split-Core Current Transducer,

High Current, 4-20mA Output

Product Overview

The H221 and the H221SP are current transducers that sense current (amperage) in the monitored conductor. The H221 amperage range is eld-adjustable, with ranges of 0-100A thru 0-300A possible. The H221SP is factory-set at a range with an upper limit specied by the customer upon ordering (100A, 150A, 200A, 250A, and 300A options available for the upper limit). Both devices transform the monitored current into 4-20 mA DC output, suitable for connection to building controllers or other appropriate data acquisition equipment. The H221 and H221SP require 12-30 VDC external power supply to generate their output.

Disconnect and lock out power to the enclosure containing the conductor to be monitored.

1. Choose a location for the sensor. The monitored conductor must pass through the center window, and the sensor must be at least ½” (13 mm) from any uninsulated conductors. Determine cable routing for the controller connection, allowing the sensor to reach the conductor.

2. Wire the output connections between the sensor and the controller (4-20 mA).

3. Snap the sensor over the conduc tor to be monitored.

4. Secure I-bar to main body of sensor with wire ties or other securing method.
