Beckhoff IP2001-B518 Fieldbus Box 8-Channel Digital Output Module

Description

Engineered for decentralized automation architectures, the Beckhoff IP2001-B518 establishes direct, field-level digital actuation via the CANopen protocol. This high-density, IP67-rated Fieldbus Box permits the direct connection of up to eight digital actuators to a high-speed CAN network, negating the need for protective electrical enclosures. Each of the eight outputs delivers up to 0.5 A at 24 V DC, making it suitable for driving solenoid valves, contactors, indicators, and small DC motors under demanding ambient environments.

Features

• 8 Digital Outputs: Standard 24 V DC switching logic with individual short-circuit protection.
• Direct CANopen Integration: Built-in node management supporting life/node guarding, emergency objects, and variable PDO mapping.
• Integrated T-Connector: Dual M12 fieldbus interfaces simplify daisy-chaining without external junction blocks.
• Submersible Enclosure: Encapsulated PA6 polyamide housing rated for IP65, IP66, and IP67 protection zones.
• Compact M8 Actuator Ports: Space-optimized termination for industrial sensors and actuator cables.

Applications

• Machine-mount control systems omitting local terminal boxes.
• Material handling systems and modular conveyor networks.
• Pneumatic valve manifold control in food processing and packaging machinery.
• Mobile equipment and material transport systems utilizing CANopen system buses.

Connections and Interfaces

Alternative Models & Compatibility

The IP2001-B518 is fully compatible with the Beckhoff KS2000 configuration software for parameterization and monitoring. When replacing legacy IP2001-B510 modules, verify standard network address switch settings and register maps, as the B518's integrated T-connector structure limits the need for external network splitting hardware.

Application Pitfalls & Engineering Notes

While the module features a total load-handling capacity of up to 4 A across all 8 channels, total heat dissipation within highly confined non-ventilated spaces must be modeled carefully. Additionally, when switching highly inductive loads, such as large pneumatic solenoid coils, external suppressor circuits or free-wheeling diodes should be placed at the load to protect the internal short-circuit monitoring circuitry from inductive kickback transients.

Commissioning & Wiring Tips

Always ensure that the CANopen network is terminated with 120-Ohm resistors at both physical endpoints of the trunk line. Use high-quality, shielded copper twisted-pair cabling for connection to the integrated M12 T-connector interface to avoid data frame corruption in environments with heavy variable frequency drive (VFD) interference.
