Product Description

Description

The BECKHOFF IP2311-B318 is a compact Fieldbus Box module designed for decentralized automation tasks, combining four digital inputs, four digital outputs, and a PROFIBUS DP network interface within a single, highly protected housing. This module provides direct connection of sensors and actuators to PROFIBUS DP networks without requiring an additional coupling unit, simplifying decentralized system architectures.

With its sealed polyamide housing and high protection rating, the BECKHOFF IP2311-B318 is optimized for mounting directly on machines and equipment outside of traditional control cabinets. This minimizes wiring complexity, reduces overall space requirements, and maintains high signal integrity in demanding industrial settings. Signal and connection routing is achieved via standardized M8 and M12 connection interfaces.

Features

  • Direct integration with PROFIBUS DP networks via integrated B-coded M12 loop-through connections.
  • Automatic baud rate detection up to 12 Mbaud for flexible network integration.
  • Four 24 V DC digital inputs with a hardware input filter of 0.2 ms for fast, reliable signal recognition.
  • Four 24 V DC digital outputs handling up to 0.5 A per channel, suitable for resistive, inductive, and lamp loads.
  • Individually short-circuit proof digital outputs with diagnostic capabilities.
  • Short-circuit protected sensor supply of up to 0.5 A derived from the control voltage.
  • Direct machine installation enabled by a fully sealed, rugged PA6 housing.

Applications

  • Decentralized input/output collection on physical machines and assembly lines.
  • Machine-mount automation configurations lacking control cabinet space.
  • Wet or dusty operating environments requiring high IP protection classes.
  • Material handling systems, conveyor systems, and distributed process setups.
