PRODUCT DESCRIPTION

The GT-AI420 analog isolation module is a 2 wire looppowered

4-20 mA signal isolator with one input/output

channel. It will accept one analog, current or voltage

output, input signal, isolate it and sink a current output

signal. The input signal has several fixed ranges for various

applications.

The device derives it’s operating power from the output

current loop that is provided by the receiving device and

has an on-board transformer that provides complete input/

output isolation.

Both the input and output are sinking type and the input

signal types are easily selected with DIP switches.
