产品介绍
The Allen Bradley 1747-BSN Backup Scanner Module is a redundancy-focused communication module designed for SLC 500 control systems using Remote I/O (RIO) networks. Its primary role is to operate as a backup scanner, automatically assuming control / the Remote I/O network if the primary scanner becomes unavailable, thereby maintaining continuous system operation.
This module is engineered for high-availability industrial applications where uninterrupted I/O communication is critical. By supporting seamless switchover, the 1747-BSN minimizes process disruptions and enhances overall system reliability. It integrates directly into SLC 500 chassis architectures and works in conjunction with primary scanner modules to form a robust redundant communication solution.
The 1747-BSN also supports RS-232 and DH+ (Data Highway Plus) interfaces, allowing flexible communication and diagnostics within complex automation systems.
