NK Technologies' ASD Series Current Sensing Switches are designed to be compatible with most automation systems

NK Technologies' ASD Series Current Sensing Switches are designed to provide a limit alarm contact. These current sensing switches are built to 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 is constructed to feature an LED display for visual indication of where the contact changes. This setpoint is made to expedite startup and improve safety by allowing trip point adjustment.

The ASD current sensing contact switch is made for monitoring, detection and control including: conveyor system jam, overload, multiple section interlock integrity; pump system loss of head pressure (open discharge line, pump runs dry, etc.); cooling towers and similar fan handling systems (over- and under-current conditions caused by open duct access door, broken drive belt or coupling, etc.).

ASD sensors are designed to be compatible with most automation systems. They are built to 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. Operating temperatures are made to be -4 to 122°F (-20 to 50°C) with 0-95% RH, noncondensing. All ASD units are designed for UL, CUL and CE Approval.
