Overview
The Allen-Bradley 1747-BSN Backup Scanner Module is a reliable redundancy solution for the SLC 500 series. It ensures uninterrupted control by enabling a secondary processor to seamlessly take over if the primary processor fails. This module enhances system reliability in demanding automation environments by supporting Remote I/O, DH+, and RS232/485 communication.
Key Features
- Seamless redundancy: Automatic switchover between primary and backup processors.
- Remote I/O support: Operates up to 3,048 meters (10,000 feet) using Belden 9463 cable.
- Dual-channel communication: One configurable channel for RIO or DH+, and a second for RS232/485.
- High-Speed Serial Link (HSSL): Transfers retentive data from primary to secondary processor.
- Local Serial Link (LSL): Allows communication between multiple 1747-BSN modules within the same chassis.
- Enhanced reliability: Functions like the 1747-SN scanner with added backup capability.
