SynchLink Overview
We designed the SynchLink system to provide the synchronization and coordination
of drive and motion control applications that are based on ControlLogix and
PowerFlex 700s stations.
About the SynchLink 4-port Splitter Block
The 4-port splitter block converts electrical signals coming from the base block to
optical signals and retransmits them simultaneously through four output ports. The
splitter block is DIN rail-mounted and is housed in a two-piece plastic enclosure.
Figure 1 identifies the components of the splitter block.
