Overview

USB-034 is a generator that allows control of 4-20 mA signals from a computer via USB. The USB side and the 4-20 mA output side are electrically isolated. It also includes a built-in loop power supply for the 4-20 mA side.
USB-034 can be used as a 4-20 mA signal generator when utilizing a computer for instrumentation and control applications.
Dedicated control commands are also provided, allowing the 4-20 mA output to be controlled from your own custom applications.
