More Information

Overview Manuals Sensor Wiring Safety Commissioning Application
  • Evaluates four safe 24 VDC digital inputs
  • Provides four pulse outputs for sensor-line diagnostics
  • Supports safety functions up to SIL 3 or Category 4 / PL e

X20SI4100 is a B&R 4-channel safe digital input module designed for the X20 System.

The module evaluates safety sensors and switches in a SafeLOGIC architecture while the pulse outputs support cross-circuit and line diagnostics.

Before installation or replacement, verify the complete material number, the required safety integrity level, input architecture, sensor type, test-pulse wiring, discrepancy and filter settings, hardware revision, X20TB52, X20BM33 or X20BM36, safety project, and validation record.

Availability, condition, price, and shipping time for X20SI4100 are confirmed during quotation.

  • Hardware revision differences must be checked before replacement
  • The safety project and checksum should be backed up before exchange
  • X20TB52 and a safety-keyed bus module are mandatory
  • Every safety channel must be function-tested after wiring changes
  • Validation records should include fault insertion and restart behavior
  • Emergency-stop and guard-switch input evaluation
  • Dual-channel safety sensor monitoring with pulse diagnostics
  • Machine safety functions requiring SIL 3 or Category 4 / PL e input processing
Description
X20SI4100 is a B&R 4-channel safe digital input module for the X20 System.

It reads 24 VDC safety signals up to SIL 3 or Category 4 / PL e, provides individually configurable software filters, and uses pulse outputs to detect faults in sensor wiring.

Before installation or replacement, confirm the complete material number, the required safety integrity level, input architecture, sensor type, test-pulse wiring, discrepancy and filter settings, hardware revision, X20TB52, X20BM33 or X20BM36, safety project, and validation record.

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 B&R X20SI4100 replace a standard four-channel digital input module?
No. It is a certified safety module and requires a compatible SafeLOGIC project, safety-keyed accessories, validated wiring, and functional testing.
Why can B&R X20SI4100 report a channel fault even when the switch changes state?
Check test-pulse assignment, cross-circuit detection, sensor supply, input pairing, filter and discrepancy settings, line resistance, and the configured safety function.
What must be checked when replacing B&R X20SI4100 with a different hardware revision?
Compare input-current and pulse-output changes, Automation Studio hardware support, firmware, safety project compatibility, and the approved validation procedure.
Can external 24 VDC signals be connected directly to B&R X20SI4100?
Only when the documented safety architecture permits it; verify common references, diagnostic coverage, line-fault detection, and the complete safety calculation.
Which accessories are mandatory for B&R X20SI4100?
Use the safety-keyed X20TB52 and X20BM33 or X20BM36, ordered separately, and verify their exact position in the safety station.
How should long sensor cables be handled with B&R X20SI4100?
Observe the documented 60 m unshielded or 400 m shielded limits and verify EMC routing, shielding, voltage drop, and the safety validation.
What tests are required after servicing B&R X20SI4100?
Perform the machine risk-assessment procedure, channel actuation tests, open- and cross-circuit diagnostics, restart checks, output-safe-state checks, and record the validated safety checksum.
