51195479-200 Honeywell I/O Link cable Set 3-Drop

Description

The 51195479-200 Honeywell I/O Link Cable Set 3-Drop is an industrial communication cable assembly designed for IO-Link-enabled automation systems, supporting connections between IO-Link masters and up to 3 field devices. As a standardized IO-Link cable, it features a structured 4-pin (Port Class A) or 5-pin (Port Class B) configuration, with core functions including simultaneous power delivery and bidirectional data transmission. Pin 1 carries voltage-based data signals, Pin 2 carries current-based data signals, Pin 3 serves as the positive power supply (supporting up to 2A current), and Pin 4 acts as the negative power/ground terminal; Port Class B adds an independent 24V power pin for high-load devices like IO-Link hubs.

It utilizes two-wire communication with a maximum data transfer rate of 230.4kbps, employing Time Division Multiplexing (TDM) technology to transmit multiple data streams over a single physical channel, ensuring real-time, reliable communication for industrial control applications. The cable can be specified with shielding to resist electromagnetic interference, and has a theoretical maximum length of 20 meters, with actual usable length dependent on environmental interference levels. Key benefits include reduced wiring complexity (replacing multi-cable setups with a single 3-wire or 4-wire assembly), simplified system integration, and support for predictive maintenance, remote diagnostics, and automatic device parameter configuration via IO-Link protocol.
