Product Description
The Allen-Bradley 1771-AF is a fiber optic converter module for the PLC-5 / 1771 platform. It is designed to convert Data Highway Plus (DH+) and Remote I/O (RIO) electrical signals into fiber optic transmission, enabling long-distance and noise-immune communication between PLC-5 systems and remote I/O racks.
This module is typically used in environments with high electromagnetic interference, grounding challenges, or extended network distances where copper-based DH+ or RIO connections are not suitable.
The 1771-AF installs in a standard 1771 I/O chassis and draws power from the 5 VDC backplane supply.
