More Information

Overview Manuals Protection Diagnostics Integration Application
  • Provides four protected 24 VDC current-sourcing outputs for 3-wire actuators
  • Includes output-independent 24 VDC and GND actuator-supply connections
  • Supports OSP behavior and software-visible output fault monitoring

X20DO4322 is a B&R digital output module designed for X20 System I/O stations.

The module connects four 3-wire actuators to an X20 station while providing output-independent actuator supply terminals and software-visible fault status.

Before installation or replacement, verify the complete material number, source-output polarity, actuator supply loading, OSP configuration, terminal and bus modules, I/O power grouping, wiring, and environmental limits.

Availability, condition, price, and shipping time for X20DO4322 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.
How do I choose between B&R X20DO4322 and X20DO4321?
Choose X20DO4322 for sourcing field circuits and X20DO4321 for sinking field circuits. Verify the complete load polarity before substitution.
Can B&R X20DO4322 use its auxiliary terminals for actuator power?
Yes, within the documented combined actuator-supply current, power, and voltage-drop limits. Do not size the connection from per-channel output current alone.
Which accessories are required for B&R X20DO4322?
Use an X20TB12 terminal block and a compatible X20BM11 or X20BM15 bus module, ordered separately.
What causes a protected shutdown on B&R X20DO4322?
Overcurrent, a short circuit, excessive inrush, or high module temperature can trigger shutdown. Check wiring and load demand before resetting the output.
How should inductive loads be connected to B&R X20DO4322?
Confirm polarity, current, switching rate, stored energy, and cable length even though the module includes an internal freewheeling diode.
Why must OSP settings be reviewed on B&R X20DO4322?
OSP behavior is project-dependent. The validated output state and channel configuration must be restored after hardware replacement.
What should be confirmed before ordering B&R X20DO4322?
Confirm the source-output requirement, 3-wire layout, group loading, actuator-supply demand, terminal and bus modules, approvals, and Automation Studio configuration.
