Link Terminal Series B7A Features

Simple wiring savings with one pair of cables
For when you want to cut down on the amount of wiring with a small number of points, communications between multiple input/output devices can be handled with a single pair of cables.
Supports data exchange between PLCs with few points. Also supports simple communications of just ON/OFF signals.
