More Information

Overview Manuals Load Sizing Diagnostics Thermal Design Application
  • Controls four higher-current type A safety outputs
  • Supports up to 2 A per channel with a 5 A total limit
  • Monitors output current and open-circuit conditions

X20SO4120 is a B&R 4-channel 2 a safe digital output module designed for the X20 System.

The module controls higher-current safety relays, contactors, or valves while supervising the output circuit for diagnostic faults.

Before installation or replacement, verify the complete material number, actuator suitability for type A outputs, 2 A channel and 5 A total limits, inrush and thermal load, output suppression, test pulses, open-circuit threshold, safe-state behavior, X20TB52, X20BM33 or X20BM36, safety project, and validation record.

Availability, condition, price, and shipping time for X20SO4120 are confirmed during quotation.

  • Each channel is rated 2 amperes but the module total is limited to 5 amperes
  • Actuator inrush and cabinet temperature must be included in the calculation
  • The potential-free load must suit the positive and negative switching architecture
  • Current monitoring supports open-circuit detection
  • Diagnostic test pulses can affect sensitive electronic loads
  • Fault acknowledgment is controlled by the validated safety application
  • Higher load current increases module and cabinet dissipation
  • Horizontal and vertical mounting have different operating-temperature limits
  • Wiring, conductor size, grouping, and enclosure cooling must be checked together
  • Higher-current safety contactor and relay control
  • Safety shutoff valves requiring up to 2 A per output
  • Monitored actuator circuits with a 5 A total module load

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 all four B&R X20SO4120 channels carry 2 A simultaneously?
No. Although each channel is rated 2 A, the official total nominal current is 5 A, so the combined load and duty cycle must be calculated.
Why does B&R X20SO4120 overheat even when no single channel exceeds 2 A?
Check total current, duty cycle, inrush, mounting orientation, ambient temperature, cabinet airflow, conductor grouping, and the complete power-dissipation calculation.
Can B&R X20SO4120 drive an electronic safety input?
Only after verifying that the load is compatible with type A positive-and-negative switching and will not react incorrectly to leakage or diagnostic test pulses.
Why can B&R X20SO4120 report an open circuit with a small load?
A load below the monitoring threshold may not be recognized; verify load current, wiring, suppression, and the diagnostic configuration.
Which accessories are mandatory for B&R X20SO4120?
Use safety-keyed X20TB52 and X20BM33 or X20BM36, ordered separately, and preserve the approved station arrangement.
Can B&R X20SO4120 replace X20SO4110 without changes?
No. Recalculate current, dissipation, wiring, protection, safety project compatibility, and actuator behavior, then repeat the validation procedure.
What should be tested after replacing B&R X20SO4120?
Test each actuator under load, safe-state shutdown, open- and short-circuit diagnostics, restart interlocks, fault acknowledgment, thermal behavior, and the validated safety checksum.
