OPTO 22 - AD3T _ G1 4 to 20 mA Analog Input, Isolated
Quick Specs:
- G1 4 to 20 mA Analog Input
- Isolated
The AD3T 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 4 to 20 mA.
This module mounts on a G1 analog mounting rack, for example the PB16AH.
