1751-SL4SP

The Allen-Bradley 1751-SL4SP is a part of the SynchLink Communication Module for ControlLogix systems. It can facilitate distributed motion implementation and drive-based systems on ControlLogix products using fiber optic communication link. It only transfers general and axis-data thus it should be used together with standard control networks such as EtherNet/IP or ControlNet for control and diagnostic data transfer. It also provides time synchronization between master and slave devices. The 1751-SL4SP is a 4-port splitter block of a SynchLink hub that converts signal from the base block from electrical to optical and sends it through its 4 output ports. It is DIN rail-mounted for installation and one base block can be plugged with up to 4 splitter blocks. It has a communication rate of 5M bit/s and power consumption of 0.300 A at 5.1V DC. Fiber-optic cable used must be 200/230 microns HCS (Hard Clad Silica) with Versalink V-System termination ranging from 1 – 300 meters. The SynchLink communication module maintains system time coordination between all ControlLogix chassis. It performs high-speed limited data transfer between chassis and shares axis data among various controllers in different chassis. The 1751-SL4SP block must be mounted within a NEMA standard enclosure to prevent personal injury. It is intended for use in an industrial environment having Overvoltage Category II Standard with a 0 - 55°C (32 - 131°F) operating temperature, a 30g operating shock, and a 5 - 90% noncondensing relative humidity.
