9.5 Relay outputs
With inductive loads (also relays and contactors),
interference suppression is necessary. If this is not
possible, protect the relay contacts using a
suppressor circuit as described below.
•
With AC voltage:
•
With DC voltage: Connect the free-wheeling
diode in parallel to the relay or contactor.

Suppressor circuit, DC/AC
9.5.1 SP 1 (as N/O contact)
1. Connect terminal 16 to the power supply terminal
for L1 of the first final control element.
2. Connect terminal 17 to the power supply
cable L1.
9.5.2 SP 2 (as N/O contact)
1. Connect terminal 19 to the power supply terminal
for L1 of the first final control element.
2. Connect terminal 20 to the power supply
cable L1.
9.5.3 Alarm relay
1. Connect terminal 21 to the power supply terminal
for L1 of the alarm unit.
2. Connect terminal 22 to the power supply
cable L1.
Note
The connection of the relay outputs
depends on the application and the
final control elements used.
Therefore consider the connections
described below as guidelines.
See
different output signals and final
control elements
and the
documentation of the final control
element.
