NK Technologies ASD Series Current Sensing Switches
NK Technologies ASD Series Current Sensing Switches provide a limit alarm contact with an easy adjustment method. These current sensing switches feature a single turn potentiometer, allowing the trip point to be set before the sensor is installed or before the monitored circuit is energized.
In conjunction, the ASD features an LED display for quick visual indication of where the contact changes, making an easy and accurate setpoint adjustment. This easily adjustable and precise setpoint simplifies and expedites startup and improves safety by allowing trip point adjustment, with no power through the sensing window.
ASD sensors are compatible with most automation systems. They provide either N.O. or N.C. magnetically-isolated solid-state output switching for control circuits up to 240 VAC (1.0 amp max). Units are offered with a choice of 0-10 or 0-200 analog setpoint ranges.
All units are equipped with an external 24 VAC/VDC power supply for higher accuracy performance with just <2 VA consumption. ASD sensors have a UL94 VO flammability rated case.
