G1 I/O family
The AD2T analog input module provides a single channel of optically isolated current-to-digital conversion. This module also provides 4,000 Vrms channel-to-channel isolation, which eliminates any ground loop problems.
Nominal input is 0 to 20 mA.
This module mounts on a G1 analog mounting rack, for example the
PB16AH.
