Input loop and Output loop

The maximum allowable system configuration is a G9SR-AD unit extended
with a maximum of two G9SR-BC units as additional safety inputs and three
G9SR-EX units as additional safety outputs.
Figure 13 - Maximum configuration
This configuration shows:
* three safety inputs
* one safety output with two NO contacts on the G9SR-AD
* three safety outputs with three NO contacts on the G9SR-Exs
Caution!
- two on the G9SR-BCs
- one on the G9SR-AD
Maximum cable length for Input loop is 20 meters.
Maximum cable length for Output loop is 2 meters.
The maximum cable length impedance for the safety input circuit
must be lower than 250 ohm.
