Product Description
The Allen-Bradley 1771-AF1 is a stand-alone fiber optic converter module designed for PLC-5 communication networks. Unlike the 1771-AF chassis-mounted version, this model operates as an external unit and does not require installation in a 1771 I/O rack.
The 1771-AF1 converts electrical Data Highway Plus (DH+) or Remote I/O (RIO) signals to fiber optic media, enabling long-distance communication and improved noise immunity in electrically harsh environments.
This unit is typically deployed in PLC-5 architectures where fiber media is required between racks, buildings, or high-interference zones.
The product is discontinued by the manufacturer but remains widely used in legacy PLC-5 installations.
