FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What sensor output topology is compatible with B&R X20DI4372?
Use 24 VDC sensors wired for the module's source-input circuit. Confirm the sensor output type and shared field reference before connection.
Can B&R X20DI4372 be used in place of X20DI4371?
Only after reviewing and adapting the field circuit. X20DI4372 is source type, whereas X20DI4371 is sink type.
What storage and transport temperatures are specified for B&R X20DI4372?
B&R specifies -40 to 85°C for both storage and transport. The permitted humidity range is 5 to 95% relative humidity, non-condensing.
How should noisy field signals be handled on B&R X20DI4372?
Adjust the module-wide software filter after confirming the process response time. Also inspect grounding, cable routing, common wiring, and signal thresholds.
How is B&R X20DI4372 identified in the Automation Studio hardware configuration?
B&R lists the device ID code as 0x22A8. Confirm this code and the complete material number when checking an existing Automation Studio project.
What should be checked when a B&R X20DI4372 channel remains inactive?
Check field voltage, source-input polarity, sensor supply loading, common wiring, terminal assignment, filter setting, and channel and module status indications.
What details should be confirmed before buying B&R X20DI4372?
Confirm the source-input requirement, 3-wire sensor arrangement, current needed by connected sensors, separate terminal and bus modules, environmental limits, and project hardware definition.
