1.3.4 Connection of safety inputs
Electrical
specifications Rating DC26V, 5mA max
Connect the relay contacts (dry contacts).
To prevent defective contact and other problems, use a device which can turn on and off
the very small load specified above.
These input signals must have redundant circuit. The two separat signals with redundant contact inputs must
perform identical operations. Connect separate contacts between pins "INA+" – "INA-" and "INB+" – "INB-" for
each input as shown in the Fig.1-2. Bear in mind that the signals cannot be connected in ways such as the one
shown in Fig.1-3.
