Figure 7-3
Field multiplexer wiring example
Example project
If you want to power the field multiplexer and all I/Os using a single power supply unit, you
can connect the power to the field multiplexer as shown in Figure 7-3. The jumper on
connector 1 (CONF
) is omitted, as the transmission medium is copper in the example
project (see page 43). The jumper on connector 3 (CONF
MA
) must only be inserted at the
master station.
Alarm contact
The field multiplexer has
a floating
alarm output (Alarm_IN and Alarm_OUT contacts at
connector 3) that allows to indicate operating errors remotely. The contact is normally open,
but it is closed in the event of an error and when the field multiplexer power supply fails.
