9 DO 0 P
Connections for fail-safe digital output 0
10 DO 0 M
(switching to P/M potential)
11 DO 2 P
Connections (relay contacts) for fail-safe
switching of the voltage buses P1 and P2.
P1 and P2 can also be used as DO 2 M
12 DO 2 M
P1 and P2 can also be used as DO 2 M
and DO 2 P (for a diagram of the wiring,
see the ET 200S Fail-Safe Modules
manual).
13 DO 1 P
Connections for fail-safe digital output 0
14 DO 1 M
(switching to P/M potential)
15 DO 2 P
Connections (relay contacts) for fail-safe
switching of the voltage buses P1 and P2.
P1 and P2 can also be used as DO 2 M
16 DO 2M
P1 and P2 can also be used as DO 2 M
and DO 2 P (for a diagram of the wiring,
see the ET 200S Fail-Safe Modules
manual).
!
Caution
If high currents occur at DO 2 P and DO 2 M, you must wire terminals 11 and 15
(DO 2 P) and 12 and 16 (DO 2 M) in parallel.
Otherwise, the temperature of the terminals cannot be prevented from rising due
to the current load.
