Terminal Assignment of the pluggable Terminal X1
For the module, a pluggable terminal X1 (245090 spring clamp terminal) for connecting
field devices is available as an accessory (not included in the scope of delivery of the
module). The X1 plug-in terminal has 24 clamping units for connecting the field cables.

All earth connections (channel 0 to 7) are connected to each other.
The output current must flow back via its earth connection.
