Description

Designed to interface decentralized I/O signals directly in the field, the IL2302-B518 serves as a robust CANopen coupler box within the Beckhoff Fieldbus Box system. This module provides direct connection of IP-Link extension modules to a CANopen network, offering a highly efficient solution for distributing digital and analog signals without requiring a protective control cabinet.

The IL2302-B518 coordinates the transfer of decentralized process data from up to 120 extension modules to the higher-level controller. By integrating the fieldbus interface, power supply connections, and IP-Link communication into a single compact housing, this module minimizes installation complexity and space requirements in demanding industrial environments.

Features

Supports connection of up to 120 IP-Link extension modules.
Handles a maximum of 128 bytes of input data and 128 bytes of output data.
Integrated T-connector for seamless CANopen network routing.
Automatic detection of data transfer rates from 10 kbaud up to 1 Mbaud.
Comprehensive CANopen feature support including Node Guarding, Life Guarding, and Emergency Objects.
Configurable via the KS2000 software tool or through standard Service Data Objects (SDOs).

Applications

Heavy industrial machinery and manufacturing lines.
Material handling and conveyor systems.
Packaging and food processing equipment.
Decentralized control installations in washdown or high-dust zones.

Interface Type	Connector Description	Function
1 x M12 plug, 5-pin	CANopen incoming bus connection
1 x M12 socket, 5-pin	CANopen outgoing bus connection (integrated T-connector)
1 x M8 male socket, 4-pin	Control voltage and sensor power feed
1 x M8 female socket, 4-pin	Power distribution to downstream modules

Installation Guidelines

Ensure the unit is securely mounted to a flat surface using the integrated mounting holes.
To maintain the IP67 protection rating, all unused M8 and M12 connection ports must be sealed with appropriate protective caps.
Verify that the control voltage is stable at 24 V DC before powering the network.
Keep bus cables isolated from high-voltage AC cables to minimize electromagnetic interference.
