Allen-Bradley 1771-AF1 | Stand-Alone Fiber Optic Converter Module

Product Overview

The 1771-AF1 Fiber Optic Converter Module by Allen-Bradley provides reliable communication for industrial automation systems. It converts Data Highway Plus (DH+) or Remote I/O (RIO) signals to fiber-optic format, extending communication distance up to 30,000 feet.

This stand-alone module supports two fiber-optic channels and uses a rackless design, enabling installation directly on panels or in enclosures. With a 5VDC external power supply and 600 mA input current, the 1771-AF1 ensures energy-efficient operation.

Equipped with status LED indicators for channel activity, this converter module allows easy monitoring of transmit and receive signals. It supports data rates up to 115,200 bps when using duplex fiber-optic cables, enhancing signal integrity across long distances.

The module is compatible with coaxial and twinaxial cables, including Belden 9463 and 1770-CD, providing flexibility in network design. Its NEMA type 12 enclosure and operating temperature range from -25°C to +70°C ensure reliable performance in demanding industrial environments.
