Allen-Bradley 1751-SL4SP SynchLink Fiber 4-Port Splitter Block

The Allen-Bradley 1751-SL4SP SynchLink Fiber 4-Port Splitter Block is a SynchLink fiber component that converts electrical signals from a SynchLink base block to four fiber-optic outputs. It is designed for DIN-rail mounting and housed in a two-piece plastic enclosure, enabling straightforward installation alongside other SynchLink modules. When used with the 1751-SLBA base block, the splitter block receives 24V DC power from the base block and retransmits optical signals through four fiber ports. The unit provides four fiber output ports and uses backplane connectors; it includes protective caps and a module locking tab for secure mounting. The 1751-SL4SP operates in an ambient temperature range of 0 to 60 °C (32 to 140 °F) and is manufactured in the United States, with a standard 1-year warranty and an estimated lead time around 49 days. This model is part of Rockwell Automation’s SynchLink fiber family for ControlLogix systems, enabling a single base block to drive multiple fiber outputs. The product carries the part number 1751-SL4SP and is cataloged as the SynchLink 4-Port Splitter Block.
