Beckhoff IP1002-B518 Fieldbus Box 8-Channel Digital Input Module

Description

Designed for decentralized acquisition of digital signals, the Beckhoff IP1002-B518 Fieldbus Box operates as an 8-channel digital input module communicating via the CANopen protocol. This ruggedized, IP67-rated device interfaces directly with physical sensors in the field, eliminating the need for protective control cabinets and reducing wiring complexity. The module features an integrated M12 T-connector for seamless CANopen bus routing, alongside standard M8 connections for electrical power supply feed and downstream distribution.

Equipped with a 3.0 ms input filter, the IP1002-B518 digital input module guarantees reliable signal acquisition from proximity switches, limit switches, and photoelectric sensors in high-noise industrial environments. The system supports automatic baud rate detection from 10 kbaud up to 1 Mbaud, enabling straightforward integration into existing CANopen industrial networks.

Features

• 8 digital input channels with a standard 3.0 ms filter delay.
• Integrated CANopen interface supporting up to 16 send and 16 receive Process Data Objects (PDOs).
• Dual M12 fieldbus connections (1 x plug, 1 x socket) with integrated T-connector functionality for daisy-chain networks.
• Short-circuit proof sensor supply sourced directly from the control voltage (maximum 0.5 A total).
• Diagnostic capabilities including life guarding, node guarding, emergency objects, and variable mapping.
• Robust polyamide housing with high resistance to vibration, shock, and electromagnetic interference.

Applications

• Distributed machinery control and conveyor automation systems.
• Process manufacturing lines requiring machine-mount, cabinet-free I/O architecture.
• Material handling plants utilizing CANopen network structures.
• Automotive assembly lines and heavy-duty robotic workstations.

Installation Guidelines

• Securely mount the Fieldbus Box using the two integrated 3.5 mm mounting holes designed for M3 screws.
• To maintain IP67 environmental sealing, ensure all unused M12 and M8 ports are sealed with appropriate industrial protective caps.
• Do not exceed the cumulative 0.5 A current limit on the sensor power supply.
• Verify that the CANopen network termination is correctly applied at both physical ends of the communication line.
• Keep power cabling and high-voltage transmission lines separated from the fieldbus signal line to limit electromagnetic interference.
