OPTO 22 – AD8T _ G1 Type K Thermocouple Input, Isolated
Quick Specs:
- G1 Type K Thermocouple Input
- Isolated
G1 I/O family
The AD8T Type K thermocouple analog input module provides a single channel of optically isolated temperature-to-digital conversion.
In addition to optical isolation, this module includes 4000 Vrms transient channel-to-channel isolation, which eliminates any ground loop problems.
This module mounts on a G1 analog mounting rack, for example the PB16AH.
