NK AS0-NCAC-120 - Current Sensing Switch, AS0 Series

• AS0 series
• Current sensing switch
• Output type = NCAC Normally Closed, 1 A @ 240 VAC
• Power Supply = 120 VAC

AS0 Series Current Sensing Switches are designed to detect very low AC current and provide a solid-state contact to open or close at a setpoint adjustable from 3 to 350 mA across two ranges. Useful for signal or lamp status monitoring, detecting low level fault currents or fan status proofing, the AS0 Series features solid-state outputs and jumper-selectable ranges, which make it a versatile choice for low-current status indication applications.

Current Sensing Switch Applications

Fan Monitoring

• Fan status in heating and drying applications.
• Identify lamp outages or other malfunctions through changes in current consumption.

• Ideal for monitoring small motors used in critical applications, for example, fan status proofing on a crucial cooling fan.

• Switch can detect LED light sources drawing less than one half watt at 120 VAC.

Current Sensing Switch Features

Wide Range of Output Options

• Dependable, solid-state relay N.O. or N.C. contacts rated at 240 VAC or 30 VDC.
• Compatible with most automation controllers.

• Inductive sensing eliminates insertion loads on monitored circuits, effectively isolating it from the unit.
• Isolated outputs simplify wiring and enhance safety.

• Setpoints are field-adjustable from 3 mA to 350 mA, speeding installation and allowing for tailored applications.

• Accepted worldwide.
