Description

 

H221 analog current transducers provide reliable load trending information for large motor loads (up to 300A), with a proportional 4-20mA signal. This model includes a span potentiometer that allows each sensor to be calibrated for maximum resolution.

 

Split core, amperage range: 0 to 100-300A AC adjustable, Analog output transducer: 4-20mA output, loop powered, large size housing. UL.

APPLICATIONS

• Load trending of large motors

 

Monitor larger motors and other loads up to 300A

• Split-core design for easy installation and fast retrofits
• Eliminates need for external CTs on large conductors
• Large openings for heavy conductors
• Monitor critical motors (compressor, fuel, etc.)

 

Loop powered 4-20mA output

• Two-wire design reduces wiring cost
• Zero and span adjustments for field flexibility
• 100% solid state...no moving parts to fail
