- Switches twelve 24 VDC loads using current-sinking FET outputs
- Provides integrated thermal protection and an internal freewheeling diode for inductive-load switching
- Supports output monitoring through channel indicators and software status
X20DO9321 is a B&R digital output module designed for X20 System I/O stations.
It integrates the documented I/O channels, electrical behavior, diagnostics, and model-specific functions into a compact X20 station slice.
Before installation or replacement, verify the complete material number, sink or source topology, terminal and bus modules, field supply, wiring, software configuration, and installed-system requirements.
Availability, condition, price, and shipping time for X20DO9321 are confirmed during quotation.

- Thermal shutdown responds to output overcurrent or short-circuit conditions
- An internal freewheeling diode supports switching of documented inductive loads
- Automatic switch-on after shutdown occurs after approximately 10 milliseconds depending on module temperature
- Output fault status is available through LEDs and software
- Output monitoring uses a documented 10 millisecond delay
- Module run, error, operating-state, and channel indicators support troubleshooting
- Storage and transport temperature range is -40 to 85°C
- Permitted relative humidity is 5 to 95%, non-condensing, during operation, storage, and transport
- Above 2000 m, the maximum ambient temperature must be reduced by 0.5°C for every additional 100 m
- Switching 24 VDC loads that require current-sinking outputs in B&R X20 control stations
- Process-control output stations used within the documented Class I Division 2 conditions
- Marine automation installations covered by the listed X20 type approvals
