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.

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.

Key Features:

#Fieldbus Boxes #Lightbus

What network interface does the Beckhoff IP2311-B200 use?

The IP2311-B200 connects to the Beckhoff Lightbus system using plastic optical fiber (APF) at a transfer rate of 2.5 Mbaud.

What is the maximum distance supported between two fieldbus boxes?

The maximum distance supported between two individual stations is 45 meters using plastic optical fiber (1000 micrometers).

Can this module be mounted directly onto a machine frame without a cabinet?

Yes. The module features an IP65/IP66/IP67 rated PA6 polyamide housing, making it highly resistant to dust, liquids, and vibration, suitable for direct machine installation.

What are the electrical ratings for the digital outputs?

The digital outputs support 24 V DC with a maximum load current of 0.5 A per channel. Each output channel is individually short-circuit proof.
