Product Description

Description

The BECKHOFF IP2321-B400 is a decentralized IP2321 series Fieldbus Box designed for machine-level automation without the need for a control cabinet. Functioning as an Interbus slave device, this module integrates digital signal processing directly into the field environment. It features a combined channel architecture consisting of digital inputs and digital outputs, allowing bidirectional signal exchange with sensors and actuators in harsh industrial conditions.

Constructed within a rugged, fully potted polycarbonate housing with IP67 protection, the IP2321-B400 withstands dust, moisture, and mechanical stress typical of decentralized plant engineering. Interbus communication and power supplies are connected via M8 screw-type connectors, while field devices interface through standard M8 sockets. This modular fieldbus device connects seamlessly to Interbus networks, handling decentralized signal acquisition and control tasks with established cycle performance.

Features

  • Decentralized IP67 Fieldbus Box for cabinet-free machine mounting
  • Interbus communication interface with standard M8 bus connections
  • Combined digital input and digital output channel configuration
  • Direct connection of sensors and actuators via M8 plug-in connectors
  • Rugged potted housing designed for industrial wet and dusty environments

Applications

  • Decentralized machine automation and material handling systems
  • Conveyor and transport technology without control cabinet enclosures
  • Automated assembly lines and packaging machinery
  • Industrial plant engineering requiring high ingress protection
