ASD Series Current Switches
ASD Series current switches monitor AC loads and provide an isolated solid-state contact for limit alarms, load monitoring and equipment interlocking. A single-turn adjustment sets the trip point, while the LED display shows the selected value and flashes when the monitored current exceeds it.
Choose ASD1 for 1–50 A adjustment or ASD2 for 4–200 A adjustment. Both use an external 24 VAC/VDC supply and a solid-core case with a 0.75-inch sensing aperture. Normally open and normally closed outputs control AC loads up to 1 A at 240 VAC.
- Set the trip point before current is present in the sensing window.
- Monitor conveyors, pumps, cooling-tower motors and other AC loads.
- Panel mounting or optional DIN-rail brackets.
- UL Listed to UL 508 and CE marked, as specified in the current datasheet.
