Connection example (type 05)
The following diagram shows the connection of a
common 24 V supply for pins 1 and 2. Please
note that:
• the outputs/valves must be protected against
short circuit/overload with an external 10 A
fuse (slow blowing)
• the supply to the electronic components and
inputs should be fused externally with 3.15 A
against short circuit/overload (recommenda-
tion)
• that the operating voltage of the sensors is
separately fused (2 A)
• that the operating voltage of the valves is
separately fused (4 A, slow blowing)
• the common tolerance of DC 24 V ± 10 %
must be observed
• the operating voltage supply to the node is
made via the adapter cable
• equalizing currents must be avoided when
both earth cables are connected, e.g. by
means of cables with appropriate cross
section as a potential compensation.
