IP2311-B200 | Beckhoff | Boîtier de bus de terrain

Description

The Beckhoff IP2311-B200 is a high-performance, distributed Lightbus fieldbus box designed to bridge local digital sensors and actuators with centralized control systems. This ruggedized I/O module integrates 4 digital inputs and 4 digital outputs within a compact, direct-to-machine mountable enclosure, eliminating the need for a separate protective control cabinet.

Operating over the proprietary Beckhoff Lightbus protocol, the module utilizes plastic optical fiber (APF) to guarantee high-speed, noise-immune communication. This fiber-optic medium ensures complete electrical isolation between the communication network and the field power, making the IP2311-B200 exceptionally resilient in high-EMC industrial environments. Designed for direct field deployment, its fully encapsulated housing carries IP65/66/67 ratings, offering robust resistance to dust, moisture, and mechanical vibration.

Features

• 4 digital inputs (24 V DC) with a 0.2 ms hardware input filter.
• 4 short-circuit proof digital outputs rated at 0.5 A per channel.
• Direct Lightbus network integration using plastic optical fiber (APF).
• Highly secure, interference-free data transmission up to 45 meters between stations.
• M8 screw-type connectors for standard sensor and actuator connections.
• Compact and light PA6 polyamide housing with a robust physical design.
• Comprehensive status LEDs for local diagnostics, channel activity, and optical link status.

Applications

• Distributed packaging machinery and materials handling systems.
• Automotive manufacturing lines demanding high EMC immunity.
• Water and wastewater treatment facilities with high moisture exposure.
• Machine tool and robotic assembly cells where cabinet space is limited.

Technical Specifications

Installation Guidelines

• Mounting: Mount the unit directly to the machine frame or flat surface using the 2 pre-drilled 3.5 mm mounting holes designed for M3 screws.
• Fiber-Optic Handling: Maintain the specified minimum bending radius of the APF optical fiber cables to prevent signal attenuation and physical damage.
• Tightening Torque: Ensure M8 sensor and power connectors are tightened to the recommended torque specification to preserve the IP67 protection rating.
• Grounding: Connect the functional ground (FE) connection to a low-impedance ground point on the machine to ensure stable internal reference potential.
