Expand Safety I/O Through Networks
Safety components distributed over many different installation locations required long and complicated wiring.
Replacing the wiring with a network between safety components greatly improves productivity
System Configuration 2
By using Safety I/O Terminals, safety I/O can be expanded easily
through the network.
Expand a Safety Network Controller using up to sixteen Input Slaves with 12 points each
(192 points total), and up to eight I/O Slaves with 16 points each (128 points total).
