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.

Designation
Load voltage of 24 VDC for: inserted
power module and associated potential
group. DO 0 and DO 1 and P1 and P2
voltage buses
Ground
Any connection for PE or voltage bus up
to the maximum rated load voltage of the
module
Load voltage of 24 VDC for: inserted
power module and associated potential
group. DO 0 and DO 1 and P1 and P2
voltage buses
Ground
Any connection for PE or voltage bus up
to the maximum rated load voltage of the
module
Connections for fail-safe digital output 0
(switching to P/M potential)
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 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).
