Allen-Bradley 1747-BSN

The Allen-Bradley 1747-BSN is a highly reliable backup scanner module designed for remote I/O applications, ensuring system continuity and redundancy. With its capability for seamless communication with operator interfaces through RS-232 channel switching, it features a versatile DH+ link for efficient data exchanges. This dual-channel module can be configured for RIO or DH+ on the first channel, while the second channel supports RS-232/485 electronic interface connections. It excels in real-time data synchronization between primary and secondary processors thanks to its High-Speed Serial Link (HSSL), along with a Local Serial Link (LSL) for status updates among multiple modules in the same chassis. Designed to perform effectively in a wide temperature range of 32-140 °F and with a relative humidity tolerance of 5-95%, the 1747-BSN is equipped to handle diverse environmental conditions, making it an essential component for robust industrial automation.
