Connections
Specifications
AD3T: All of the lower A terminals on the
mounting rack are tied together. These provide a
convenient tie point for shared loop source return.
To use the AD3T module with a common loop
power supply, connect any one lower A terminal
to the shared loop source “-”, then jumper upper
A to lower A for each AD3T.
