Description

WSS-420 Series Wireless 4-20mA Transmitter / Receiver Set features a factory programmed transmitter / receiver matched set. The transmitter sends 4-20mA current measurements to a base receiver up to 6 miles away depending on model using license free wireless RF technology. The receiver base provides analog current (4-20 mA) or analog voltage (1-5V DC) output. Each Transmitter/Receiver set is factory coded as a matched set and requires no field programming. Models can be solar powered.
