Wiring of the relay output
Note!
ƒ
Switching of control signals:
– Use shielded cables
– HF-shield termination by PE connection
– The minimum load for a correct through-connection of the relay contacts
is 10 V DC and 10 mA. Both values must be exceeded at the same time.
ƒ
Use shielded cables for switching the control signals and establish the
HF-shield termination through a PE connection.
ƒ
For the switching operation of mains potentials, shielded cables are
sufficient.
ƒ
To protect the relay contacts, use a corresponding suppressor circuit in case
of an inductive or capacitive load!
ƒ
The service life of the relay depends on the load type (ohmic, inductive, or
capacitive) and the height of capacity to be switched.
Note!
The following notes are described in detail in the Software Manual in the
section ”I/O terminals”:
ƒ
Use code C00621 to define the relay function.
ƒ
Use code C00118 to define the relay switching status.
