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.
Can every channel of B&R X20DI4371 be used as a counter?
Yes. Each of the four inputs has a corresponding 16-bit event counter; the maximum counter frequency applies when the input filter is switched off.
Which sensor output type matches B&R X20DI4371?
Use 24 VDC sensors compatible with sink-input, 3-wire connections. Confirm polarity and reference wiring before installation.
What storage and transport temperatures are specified for B&R X20DI4371?
B&R specifies -40 to 85°C for storage and transport. Keep the module within 5 to 95% relative humidity, non-condensing.
Can B&R X20DI4371 replace X20DI4372 directly?
Not without reviewing the field wiring. X20DI4371 is sink type and X20DI4372 is source type, so the sensor output topology and commons are different.
Why can a counter on B&R X20DI4371 undercount pulses?
Check that the input filter is disabled for the required frequency, the pulse rate stays within the documented limit, and the signal meets the voltage thresholds without excessive noise.
How much sensor load can be connected through B&R X20DI4371?
The connected 3-wire sensors must remain within the documented shared sensor-supply current and voltage-drop limits; total load should be calculated before commissioning.
What should be recorded before replacing B&R X20DI4371?
Record the sink-input wiring, filter value, counter edge settings, I/O mapping, terminal assignments, and the validated Automation Studio hardware configuration.
