Limit Alarm Current Sensing Contact Switches
New 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 product features an LED display for quick visual indication of where the contact changes, making the product have accurate setpoint adjustments. The precision in the setpoint simplifies startup and improves safety by allowing trip point adjustment, with no power through the sensing window. Compared to alternative technologies, these current sensing contact switches are ideal for reliability. Product is for monitoring, detection and control, including: conveyor system jam, overload, multiple section interlock integrity, pump system loss of head pressure, cooling towers and similar fan handling systems. Product is compatible with most automation systems. They provide N.O. or N.C. magnetically-isolated solid-state output switching for control circuits up to 240 VAC. Units are offered with a choice of 0-10 or 0-200 analog setpoint ranges.
