Modules
Attention
This module has no power contacts for ground (earth). For field supply with
ground (earth) to downstream I/O modules, a supply module will be needed.
The module can be used with all couplers/controllers of the
WAGO-I/O-SYSTEM 750 (except for the economy types 750-320, -323, -324
and -327).
