Bihl+Wiedemann BWU 2267 Slave module

1. Product Detailed Description

The BWU2267 acts as a bridge, allowing seamless data exchange between field-level sensors/actuators and a central controller. This specific model features a single AS-i master configuration and integrates an internal decoupling circuit, which simplifies the power supply requirements for the AS-i line. It is housed in a compact stainless steel casing for durability in industrial settings.

2. Key Technical Parameters

Below are the primary specifications for the BWU2267:

3. Product Advantages

• Dual Protocol Support: Provides flexibility by supporting both EtherNet/IP and Modbus TCP, making it compatible with a wide range of PLCs (e.g., Rockwell, Schneider, or various SCADA systems).

• Integrated Decoupling: Eliminates the need for a specialized AS-i power supply in many cases. You can often power the system using a standard 24V DC supply, reducing hardware costs.

• Easy Diagnostics: The built-in LCD screen allows for on-site troubleshooting and address assignment without requiring a PC.

• Enhanced Reliability: The stainless steel housing provides excellent heat dissipation and electromagnetic shielding.

• AS-i 3.0 Compatibility: Supports advanced addressing modes and high-speed data transmission for complex sensors and safety modules.

4. Important Considerations (Precautions)

• Power Loading: Ensure that the total current consumption of the connected AS-i modules does not exceed the 4A limit of the integrated decoupling circuit.

• Network Addressing: AS-i slave addresses must be unique. Use the gateway’s display or a handheld programmer to assign addresses before commissioning.

• Environmental Protection: As an IP20 rated device, it must be installed in a control cabinet or an enclosure protected from moisture and dust.

• Firmware Updates: Always check for the latest firmware to ensure compatibility with the newest EDS files for your PLC.

5. Product Applications

The BWU2267 is widely used in automation sectors that require distributed I/O management:

• Conveyor Systems: Managing many digital inputs/outputs over long distances with minimal wiring.

• Packaging Machinery: Coordinating sensors and pneumatic valves.

• Food & Beverage: Reliable control in processing lines where stainless steel components are preferred.

• Automotive Assembly: Connecting safety and standard signals back to a centralized EtherNet/IP control architecture.
