Installation instructions
For reasons of safety it is not permissible to connect low voltages (up to 50V)
and higher voltages (50 … 250 V) to the same module.
If a PCD module is connected to a higher voltage (50 … 250 V), approved
components for this voltage must be used for all elements that are electrically
connected to the system.
Using higher voltage (50...250V), all connections to the relay contacts must be
connected on the same circuit, i.e. in such a way that they are all protected against
one AC phase by one common fuse. Each load circuit
may also be protected individually.
I/O modules and I/O terminal blocks may only be plugged in and removed when the
PCD and the ex24 V are disconnected from the power supply.
The Annex, Section A.4 "Relay contacts" contains measurement details and
suggested wiring for the relay contacts. For safe switching and a long service life,
these figures must be observed.
