16-Logic Input Module
Function
This digital module allows the
monitoring of 1 to 16 logic inputs by the
MX43.
In the 8-line version, the central unit
can manage a maximum of 32 logic
inputs distributed, for example, either
on 32 logic input modules with one
input declared per module, or on 2
modules with 16 logic inputs each.
In the 4-line version, the central unit
can manage a maximum of 16 logic
inputs.
