More Information

Overview Manuals Counting Measurement Approvals Application
  • Combines two 24 VDC sink inputs with two 50 kilohertz event counters
  • Supports gate-time measurement on either input, one measurement channel at a time
  • Provides short-circuit-protected 24 VDC and GND connections for sensor supply

X20DI2377 is a B&R digital input and counter module designed for X20 System I/O stations.

It integrates the documented I/O channels, electrical behavior, diagnostics, and model-specific functions into a compact X20 station slice.

Before installation or replacement, verify the complete material number, sink or source topology, terminal and bus modules, field supply, wiring, software configuration, and installed-system requirements.

Availability, condition, price, and shipping time for X20DI2377 are confirmed during quotation.

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 both inputs of B&R X20DI2377 count pulses at the same time?
Yes. Both inputs can be configured as event counters; confirm the Automation Studio channel configuration and the documented maximum input frequency.
Can B&R X20DI2377 perform gate measurement on both channels simultaneously?
No. Gate measurement is available on input 1 or input 2, but only one gate-time measurement can be active at a time.
What storage and transport temperatures are specified for B&R X20DI2377?
B&R specifies -40 to 85°C for both storage and transport. Relative humidity must remain within 5 to 95% and non-condensing.
What sensor wiring is suitable for B&R X20DI2377?
Use 24 VDC sensors compatible with sink-input, 3-wire connections. Verify signal polarity, sensor current, pulse duration, and reference wiring.
Why might B&R X20DI2377 miss fast input pulses?
Check that the software filter is not suppressing the pulses, the pulse and pause durations meet the documented limits, the frequency is within range, and the signal reaches the switching thresholds.
Can the sensor supply on B&R X20DI2377 power any 24 VDC sensor?
Only if the connected sensor load remains within the module's documented shared supply limit and wiring requirements. Check total current and voltage drop before connection.
What should be backed up before replacing B&R X20DI2377?
Record the channel mode, counter and gate-measurement settings, input-filter value, I/O mapping, terminal wiring, and the validated Automation Studio project.
