SKU : X20MM4331
Brand : B&R
Material number:
  • 4 half-bridge outputs
  • High component density
  • 3 A continuous current
  • 5 A peak current
  • Readable current

The 4 outputs on the motor module are designed as half-bridge outputs. The continuous current per channel is 3 A at a peak current of up to 5 A. Integrated diagnostics offer the possibility to read back the output current for each channel using the application.

The module offers extensive possibilities for controlling motors, valves or resistive loads and is particularly well suited for controlling brush DC motors. The outputs can be switched on/off and short-circuited.
