Electrical Connection
The electrical connection is carried out by using removable 9-pin and 11-pin terminal blocks.
These terminal blocks differ in their connection system (spring terminals or screw terminals,
cable mounting from the front or from the side). For more information, please refer to the
chapter Terminal Blocks for S500-eCo I/O Modules
Blocks" on page 1164. 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 outputs:
