Operating Manual ZX20T/TP/TC
5.6.1 Digital Outputs
The connection of digital outputs is shown in fig. 9. Various actuators (e.g. relays)
can be connected to the terminals of the outputs. Their 0 V potential is connected to
the 0 V potential of the voltage supply (terminal "M").
If the outputs are enabled, the voltage generated at the connecting terminals "U+"
and "M" are connected through to the outputs. The voltage at "U+" and "M" can
deviate from the supply voltage U
B
; For the permitted voltage range see chapter 12
"Technical Data". If a separate voltage source is used, an additional connection of
the 0 V output of the voltage source with the 0 V output of the operating voltage
source is
not
necessary, since the terminals "M" are internally connected in the
device.
