- Relay operation: break contact
The relay contact can be operated logically as a break con-
tact (via software). The relay position is inverted and issued.
Switch (break function)
The fixed relay positions (open, closed) within the other
functions are triggered directly. An inversion by means of
the break contact function is no longer carried out for these
fixed relay positions.
Status response
Each channel can deliver a status response, depending on
the parameter settings. This always conveys the actual state
of the output (1= relay closed; 0= relay opened).
After bus voltage recovery, the relay is normally closed
in the “break contact” function and if the status feedback
function is active, a status response telegram is generated
with the value “1” after approx. 17 s. In this case, a function
with a higher priority enforces a different state and the
corresponding status response telegram is produced.

- Relay operation: changeover contact
The changeover function is only available for the odd-num-
bered channels i.e.1, 3, 5, 7, etc. The even-numbered chan-
nels are integrated in the changeover function as a second
contact.
In this operation mode, the two adjacent channels e.g. “1”
and “2” are combined logically as a changeover contact. The
two relays then work inversely to each other. The switching
state is determined by the odd-numbered channel “1”.

Relay operation
The operation mode of the relay can be set via the parame-
ter “Relay operation”. The relay can be used as a “break con-
tact”, “make contact”, “changeover contact” or as a flashing
indicator. The changeover function is only available for the
odd-numbered channels i.e.1, 3, etc. The even-numbered
channels are integrated in the changeover function as a
second contact.

When changing over the relay operation mode,
parameter settings and linked group addresses are
modified by the ETS program. For this reason, the
relay operation mode should be set before configur-
ing the device.
- Relay operation: make contact
The relay in the switch actuator has a make contact. The
switching state is transmitted directly to the relays.
Switch (make function)
Status response
Each channel can deliver a status response, depending on
the parameter settings. This always conveys the actual state
of the output (1= relay closed; 0= relay opened).
After bus voltage recovery, the relay is normally opened in
the “make contact” function. When the contact is opened
and the status feedback function is active, no “0” telegrams
are generated. In this case, a function with a higher priority
enforces a different state and the corresponding status
response telegram is produced.
