Product Overview
The Allen-Bradley 1771-AF module is a fiber-optic converter module in the PLC-5 (Bulletin 1771) family. It occupies a single slot within a 1771 I/O chassis and enables point-to-point (or star) communication over fiber-optic cable to another module up to approximately 6 500 ft (2 000 m) away. It serves as a media converter for Remote I/O or Data Highway Plus signals, extending communication distances in electrically noisy environments. Typical applications include linking PLC-5 racks or bridging remote stations over fiber-optic links with immune signal transmission. Part number 1771-AF.
