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.
What field-load wiring is compatible with B&R X20DO9321?
Use loads and power wiring designed for a sinking output circuit. Confirm the positive supply, return path, and common-potential arrangement before energizing the module.
Can B&R X20DO9321 be exchanged with X20DO9322?
Only after a wiring review. X20DO9321 is sink type and X20DO9322 is source type, so they are not polarity-equivalent replacements.
How is B&R X20DO9321 identified in the Automation Studio hardware configuration?
B&R assigns ID code 0x1B9B to X20DO9321. Use this code together with the complete material number when checking the installed hardware definition.
How should inductive devices be connected to B&R X20DO9321?
Check the actuator's inrush, stored energy, switching rate, and the module's documented inductive-load behavior; add external suppression when required by the load manufacturer.
How should an overload indication on B&R X20DO9321 be investigated?
Check for excessive channel or group current, shorted field wiring, inadequate I/O supply, elevated temperature, and the output status reported in software.
What insulation voltage is specified between the output group and bus on B&R X20DO9321?
B&R specifies an insulation voltage of 500 Veff between the channel group and the bus. This value does not mean that the individual output channels are isolated from one another.
What selection details matter before ordering B&R X20DO9321?
Confirm the sink-output requirement, load current and polarity, 1-wire terminal plan, X20TB12 and bus-module availability, temperature derating, and Automation Studio configuration.
