Frequently Asked Questions

What is the communication protocol and how do I connect the BWM427 to my PLC?

The BWM427 uses the RS485 physical layer with the Modbus RTU protocol. Connect the sensor's A and B lines to your PLC's RS485 port, ensuring proper termination and bias resistors if required for your network. Assign a unique Modbus slave address via configuration software for multi-drop communication.

What is the power supply requirement and how do I wire it?

The sensor operates from a wide 9–35V DC supply, making it compatible with common 12V or 24V industrial power systems. Connect the positive supply to the V+ terminal and the negative to the GND terminal. Ensure the power source can provide the 20–40mA operating current.

Can this sensor be used outdoors or in wet environments?

Yes, the BWM427 is housed in an IP67-rated enclosure, providing protection against dust ingress and temporary immersion in water up to 1 meter for 30 minutes. It is suitable for outdoor installation and harsh industrial environments.

How is the measurement data formatted and what is the output frequency?

Angle data for both X and Y axes is transmitted as 32-bit floating-point values over Modbus registers. The output data rate is configurable from 5Hz to a maximum of 100Hz, allowing you to optimize between response speed and network load for your application.
