Active current output V3 / V4
When the 'loop power supply 24 V DC, blue' plug-in card is
used, the current output on the plug-in card can also be wired
as the active current output.

Connection versions digital output 41 / 42, 51 / 52
Depending on the wiring of digital outputs DO 41 / 42 and 51
/ 52, they can be used parallel or only individually. The
electrical isolation between the digital outputs also depends
on the wiring.
