Description

The Beckhoff IL2300-B518 is a high-performance, decentralized Fieldbus Box designed to establish direct communication between a CANopen network and extension IP67 I/O modules. Engineered for rugged industrial environments, this coupler box eliminates the need for protective control cabinets by offering a fully sealed housing. It supports automatic baud rate detection and efficiently manages decentralized digital and analog signals. The integrated T-connector design simplifies network looping and minimizes cabling complexity on the factory floor.

Features

High-Capacity Expansion: Connects up to 120 extension modules, managing up to 128 bytes of input and 128 bytes of output data.
Robust Signal Handling: Directs up to 960 digital inputs/outputs and up to 60 analog inputs/outputs.
Advanced CANopen Support: Built-in support for up to 16 send and 16 receive Process Data Objects (PDOs), node guarding, life guarding, emergency objects, variable mapping, and store/restore parameters.
Flexible Configuration: Easily configurable via the Beckhoff KS2000 software suite or directly through the controller using Service Data Objects (SDOs).
Industrial-Grade Housing: Sealed structure certified to IP65/66/67 ratings for complete protection against dust, water jets, and temporary immersion.

Applications

Automated assembly lines and material handling systems.
Machine tool manufacturing and decentralized robotics controls.
Harsh wet-room applications including food and beverage processing.
Automotive manufacturing plants and heavy machinery.
