BECKHOFF IP2311-B400 Fieldbus Box

Description

Designed for distributed machine-mount installations, the IP2311-B400 fieldbus box facilitates direct, cabinet-free connection of digital signals in rugged industrial environments. This compact I/O module integrates 4 digital inputs and 4 digital outputs, routing them through standard M8 screw-type connectors for secure wiring to local sensors and actuators. Operating at data transfer rates up to 500 kBaud, the unit handles communications over distances up to 400 meters between modules using specialized LiYCY cabling. The fieldbus interface is established via robust 9-pin M23 connectors, allowing reliable integration into decentralized control architectures. System configuration and diagnostics can be performed seamlessly using the KS2000 software interface.

Features

• Cabinet-free, decentralized mounting with IP67-rated environmental protection.
• Four digital inputs (24 V DC) featuring a built-in 0.2 ms hardware input filter.
• Four short-circuit-proof digital outputs rated up to 0.5 A per channel.
• Tough, glass-fiber reinforced polyamide (PA6) housing material for industrial durability.
• Direct integration with fieldbus systems via dual 9-pin M23 connections (male and female).
• Flexible parameter assignment and diagnostic capabilities supported by the KS2000 configuration tool.

Applications

• Automotive assembly and conveyor lines.
• Material handling and sorting automation.
• Food processing and high-moisture packaging zones.
• Heavy machinery and decentralized process control.

Installation Guidelines

• Mount the module directly on flat machinery surfaces using the 2 pre-molded fixing holes (3.5 mm diameter, suitable for M3 screws).
• Ensure all unused M8 and M23 connections are securely fitted with appropriate IP67 protection caps to prevent moisture ingress.
• Maintain clear pathways for the fieldbus cabling to prevent tight bend radii and mechanical stress on the M23 connectors.
• Verify that the total current draw of the sensors connected to the M8 ports does not exceed the maximum supply limit of 0.5 A.
