Product Introduction
Current Sensor H221Description
The H221 analog current sensor provides reliable load trend information for large motor loads (up to 300A) with a proportional 4~20mA signal. This model includes a span potentiometer, allowing each sensor to be calibrated for maximum resolution.
Current Sensor H221 Applications:
Large motor load trends
Monitoring larger motors and other loads up to 300A
Current Sensor H221Features
Split-core design for easy installation and quick retrofitting
Eliminates the need for large external CT conductors
Large opening for heavy conductors
Monitor critical motors (compressors, fuel, etc.) status
Loop-powered 4-20mA output
Two-wire design reduces wiring costs
Flexible zero and span adjustment
100% solid state... no mechanical moving parts to fail
5-year warranty
