Description

The BECKHOFF IP2021-B400 is a high-performance Fieldbus Box designed for decentralized automation environments. Acting as an Interbus-compatible distributed I/O module, this device enables direct machine-mount installation without the need for a protective control cabinet. It is equipped with 8 digital outputs operating at 24 V DC to interface directly with actuators at the field level.

Engineered for harsh industrial operating conditions, the BECKHOFF IP2021-B400 features a fully sealed IP67-rated housing. This construction ensures robust resistance to moisture, dust, and mechanical stress, reducing overall wiring complexity and installation costs. By transferring actuator signals directly from the Interbus fieldbus network to local machinery components, it optimizes cycle times and enhances system reliability.

Features

  • Interbus fieldbus interface for decentralized control topologies.
  • 8 digital outputs rated at 24 V DC.
  • High switching capability of up to 2 A per output channel.
  • Rugged IP67 protection class housing, dust-tight and resistant to water penetration.
  • M8 screw connector technology for secure and compact I/O wiring.

Applications

  • Decentralized machine control and machine-mount automation architectures.
  • Direct integration in conveyor lines, material handling, and assembly systems.
  • Cabinet-free wiring topologies in manufacturing and packaging environments.
  • Interbus-based industrial control networks.
