Chapter 2.5 “AC500-
eCo” on page 925.
The connection is carried out by using a removable 9-pin terminal block. These terminal blocks
differ in their connection system (spring terminals or screw terminals, cable mounting from the
front or from the side). The terminal blocks are not included in the module's scope of delivery
and must be ordered separately.
The following block diagram shows the internal construction of the digital inputs:
