More Information

Overview Manuals Actuator Selection Diagnostics Validation Application
  • Controls four type A safety output channels
  • Monitors output current and detects open circuits
  • Supports suitable safety functions up to SIL 3 or Category 4 / PL e

X20SO4110 is a B&R 4-channel 0.5 a safe digital output module designed for the X20 System.

The module controls safety actuators such as relays or valves whose load is not tied to a separate reference potential.

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

Availability, condition, price, and shipping time for X20SO4110 are confirmed during quotation.

  • Type A outputs are intended for suitable potential-free loads
  • Relay and valve coils must be checked for inrush and suppression behavior
  • Loads tied to another reference potential require a different approved architecture
  • Current monitoring supports open-circuit detection
  • Test pulses can interact with sensitive electronic loads
  • The safety application determines how channel faults are acknowledged
  • X20TB52 and a safety-keyed bus module are mandatory
  • Every output must reach the safe state during the documented fault tests
  • The validated safety checksum and restart behavior must be recorded
  • Safety relay and contactor-coil control
  • Safety shutoff valves with compatible potential-free coils
  • Machine safety circuits requiring monitored 0.5 A outputs
Description

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 X20SO4110 drive an actuator with a shared external reference potential?
Type A outputs are intended for suitable potential-free loads; verify the actuator circuit and official safety architecture before connection.
Why can B&R X20SO4110 report an open circuit when an actuator is present?
Check load current against the monitoring threshold, terminal wiring, coil continuity, suppression components, contact resistance, and configured diagnostics.
Can an electronic load react to B&R X20SO4110 test pulses?
Yes. Sensitive loads can respond to short diagnostic pulses, so verify input filtering, maximum capacitive load, and B&R-approved load behavior.
What should be checked for a relay or valve coil on B&R X20SO4110?
Check steady current, inrush, inductive suppression, leakage sensitivity, release time, wiring, total module current, and the required safety response.
Which accessories are mandatory for B&R X20SO4110?
Use X20TB52 and X20BM33 or X20BM36, ordered separately, and preserve the safety-keyed station arrangement.
Can B&R X20SO4110 be replaced by X20SO4120 without engineering review?
No. The higher-current model can differ in dissipation and load behavior; update the safety project and power calculation and repeat validation.
What tests are needed after replacing B&R X20SO4110?
Test each actuator, safe-state shutdown, channel diagnostics, open- and short-circuit response, restart interlocks, fault acknowledgment, and the validated safety checksum.
