NK ATR16-420-24L-LS - AC Current Operated Switch, AT/ATR-LS Series

• AC current transducer
• Measurement = True RMS responding output for distorted current
• Range = 0-1600 A
• Output type = 4-20 mA
• Power supply = 24 VDC loop-powered
• Case style = split-core, base terminals, DIN rail mounting

AT/ATR-LS Series Current Transducers combine a current transformer and signal conditioner into a single package. The large, easy-to-install, split-core design allows for installation over existing conductors without the need to disconnect the monitored load, even in applications where there are multiple conductors per phase. For new installations, the process is just as easy. Just remove the top portion of the sensing ring, place the conductors inside, and snap the top back in place. The transducer uses two wires to connect to the power supply and the load (a programmable logic controller, a panel meter or a data acquisition system).

Grinder/Shredder Application

AC Current Transducer Applications

Monitor Large Machines

• Measure the current use to detect over or under current conditions before they cause break downs.

Water Delivery and Treatment

• Detect open discharge lines.
• See clogged filters or blocked intake to pumps.

Generators

• Keep the power system running by monitoring the output.

AC Current Transducer Features

Industry Standard Output

• 4-20 mA signal proportional to the AC current.
• Compatible with most automation systems.

• Use the "live zero" output to verify proper connections (sensor output with no current flowing confirms the system is ready to go).

• Eliminates zero and span potentiometer adjustment.

• Sensing window provides ample space for bus bar, single or multiple conductors.

• Simple snap onto DIN rail for secure mounting.

• Accepted worldwide.
