A-B 1747-SN
The Allen-Bradley 1747-SN module is a remote I/O scanning module for the Rockwell Automation SLC 500 series PLC. It is used to establish communication between the SLC 500 PLC and remote I/O devices, enabling the expansion of distributed I/O. With this module, I/O modules can be placed away from the PLC, thereby increasing system flexibility, scalability, and reducing wiring.
Main function
Remote I/O communication: Establish communication with remote I/O devices (such as the 1746 series I/O module) to achieve data exchange.
Scan: Periodically scan the status of remote I/O devices and update the data to the PLC.
Expand I/O points: Expand the PLC’s I/O points by adding remote I/O devices.
Improve system reliability: Distributed I/O improves system reliability and reduces single points of failure.
