I/O Modules
750-428 [4 DI AC/DC 42 V 20 ms]
An optocoupler is used for electrical isolation between the bus and the field
side.
Any configuration of the input modules is possible when designing the
fieldbus node. Grouping of module types is not necessary.
Attention
This module has no power contacts. For field supply to downstream I/O
modules, a supply module will be needed.
The digital input module 750-428 can be used with all couplers/controllers of
the WAGO-I/O-SYSTEM 750.
