Switch group interface
The routing elements of switch groups 1..20 are controlled via control inputs I3 and
I4. Control is effected using external switches (door contacts, time switches, etc.).
The signal no-load voltage is approx. 40 VDC, the short-circuit current approx.
4 mA.
The permissible switch and loop resistances are as follows:
•
Active state (On): < 4.5 k
Ω
•
Passive state (Off ): > 11 k
Ω
Warning
The control inputs do not require an external power supply but they must
have a floating connection.
There are no special requirements for the cables.

Switch group control via the control inputs
Other conditions:
•
The switch group configuration determines which of the switch groups 1…20
are switched.
•
An options card’s control inputs can control one or more switch groups.
•
The same switch group can only be switched by the control inputs of one op-
tions card.
•
Control of the switch groups using the control inputs takes priority over control
using */# procedures.
