16 DO 2M
P1 and P2 can also be used as DO 2 M
and DO 2 P (for wiring diagram see
ET 200S Manual, Fail-safe Modules).
!
Caution
If high currents are encountered at DO 2 P and DO 2 M, terminals 11 and 15
(DO 2 P) and 12 and 16 (DO 2 M) must be wired in parallel.
Otherwise terminal overheating caused by the current load cannot be excluded.
