Description


The general purpose ultrasonic switch and controller provides non-contact level detection up to 24.6′ (7.5 m) with 3 SPDT 60 VA 1A relays. EchoSwitch II features digital push button configuration, eliminating target calibration. Each relay can be configured on a single set point to control pumps, valves or alarms. In addition, all 3 relays can be simplexed, duplexed or triplexed. EchoSwitch II now features an integrated timer with pump/valve delay and timed pump alternation. The switch is well suited for a broad range of corrosive, waste and slurry type media. EchoSwitch II is broadly selected for atmospheric day tanks, pump lift stations and waste sump applications.
