Product Identiﬁcation

Part Number Description

H421 High current monitoring, 4-20 mA analog output, scalable amperage range (1000 to 2400 A upper limit)

H421SP High current monitoring, 4-20 mA analog output, amperage range set at factory (1000, 1200, 1400,

1600, 1800, 2000, 2200, or 2400 A upper limit, specied by customer at ordering)

Product Overview

The H421 and the H421SP are current transducers that sense current (amperage) in the monitored conductor. The

H421 amperage range is eld-adjustable, with ranges of 0-1000A thru 0-2400A possible. The H421SP is factory-

set at a range with an upper limit specied by the customer upon ordering (1000A, 1200A, 1400A, 1600A, 1800A,

2000A, 2200A, 2400A, and 2400A options available for upper limits). Both devices transform the monitored current

into 4-20mA DC output, suitable for connection to building controllers or other appropriate data acquisition

equipment. The H421 and H421SP require a 12-30 VDC external power supply to generate their output.
