Features:

  • Supporting seamless communication between various fieldbus protocols ,ensuring interoperability in mixed-network environments.
  • Capable of data transfer rates up to 1 Mbps, enabling real-time control and fast data exchange critical.
  • Built to withstand harsh conditions and featuring durable M12 connectors.
The BIHL+WIEDEMANN BWU1840 solves the challenge of integrating diverse equipment by acting as a universal translator on your network. It supports major industrial protocols including Modbus, CANopen, DeviceNet, and PROFIBUS. This flexibility allows the module to bridge communication between older legacy devices and modern PLC-based control systems, protecting your capital investment in existing machinery while enabling the adoption of new automation technologies without costly, complex hardware changes.

For applications requiring precise timing, such as motion control or high-speed packaging, the BWU1840 delivers with data transfer rates reaching up to 1 Mbps. This high-speed capability ensures that critical control signals and sensor data are transmitted without latency, maintaining the efficiency and accuracy of your production line. By facilitating such rapid communication between the field level and the control system, the BWU1840 ensures that your automation processes remain responsive and productive even under demanding operational loads.

Industrial environments often expose electronics to extreme temperatures, vibration, and electrical noise. The BWU1840 is engineered to perform reliably under these conditions, operating effectively in temperatures ranging from -20°C to +70°C. Its robust build is complemented by secure M12 connectors, which provide a vibration-resistant and weather-sealed connection. This durability translates to a longer operational lifespan and reduced maintenance costs, ensuring the module continues to function correctly even in locations like outdoor facilities, foundries, or food processing plants.

The BWU1840 BIHL+WIEDEMANN Interface Master Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
