FIELD SIGNAL PATH

How a 3-wire sensor becomes X20 process data

Separate field power, signal conditioning and counter evaluation.

PROCESS STAGE 01

POWER SENSOR

The protected module supply provides 24 VDC and ground for connected 3-wire devices within the total-current limit.

PROCESS STAGE 02

QUALIFY INPUT

Hardware and configurable software filtering reject unwanted transitions before the signal reaches application logic.

PROCESS STAGE 03

COUNT EVENTS

Each input can evaluate a selected edge with a cyclic 16-bit counter when the counter function is enabled.

MACHINE FIT

Proximity switches, photoelectric sensors and pulse-producing devices in compact X20 stations.

WIRING GATE

Confirm sink logic, terminal mapping, sensor current and filter settings before enabling the counter path.

PURCHASING FAQ

Frequently Asked Questions from Buyers

Make sourcing and migration decisions with confidence.

How are 3-wire field sensors connected to B&R X20DI4371?

Use the documented sink-input terminals together with the module-provided 24 VDC and ground, and keep each sensor wired to the correct channel on X20TB12.

When can all four event counters on B&R X20DI4371 reach 1 kHz?

The four 16-bit counters support up to 1 kHz when the input filter is switched off and the incoming square-wave signal satisfies the input thresholds.

How much sensor load can B&R X20DI4371 supply across its field connections?

The protected sensor supply has a 0.5 A summation-current limit and a maximum documented power of 12 W for the connected sensors.

Which mandatory terminal components are required to install B&R X20DI4371?

Use one X20TB12 terminal block and a compatible X20BM11 or X20BM15 bus module, selected for the station arrangement.

What must be compared before B&R X20DI4371 replaces another X20 digital-input slice?

Compare sink/source logic, channel count, 3-wire terminal assignment, counter use, filter timing, sensor supply and Automation Studio hardware configuration.

What should be included when requesting documentation or a quotation for B&R X20DI4371?

Provide the station layout, bus module, terminal block, sensor types, counter frequency, quantity, destination and required delivery date.
