More Information

Overview Manuals Power Feed Protection Current Sharing Application
  • Provides eight protected 24 VDC current-sinking outputs rated for high-current loads
  • Receives external actuator power directly at the module and monitors the supply in software
  • Allows documented parallel output connection when higher current is required

X20DO8331 is a B&R digital output module designed for X20 System I/O stations.

The output supply is connected directly to the module, so an additional X20 supply module is not required for this output group.

Before installation or replacement, verify the complete material number, external supply and line fuse, per-channel and total current, permitted parallel connection, load inrush, terminal and bus modules, and thermal derating.

Availability, condition, price, and shipping time for X20DO8331 are confirmed during quotation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

  • The actuator supply is connected directly to the electronic module
  • A maximum 10 ampere slow-blow line fuse is required for the external supply
  • The module does not use the I/O supply potential carried through the bus module
  • Thermal shutdown protects outputs during overcurrent or short circuit
  • Integrated protection supports inductive-load switching and supply reverse-polarity protection
  • Restart after overload shutdown depends on module temperature
  • B&R permits outputs to be connected in parallel to increase available output current
  • Parallel channels must be commanded and wired consistently for the validated design
  • The module's total nominal current and thermal derating still apply to the complete output group
  • Switching high-current 24 VDC actuators in X20 machine-control stations
  • Distributed output groups that receive field power directly at the electronic module
  • Documented current-sharing applications using parallel output channels
Description
X20DO8331 is a B&R digital output module for the X20 System distributed I/O platform.

It provides eight high-current sinking outputs, direct external field-power feed, software supply monitoring, and protected inductive-load switching.

Before installation or replacement, confirm the complete material number, external supply and line fuse, per-channel and total current, permitted parallel connection, load inrush, terminal and bus modules, and thermal derating.

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.
Does B&R X20DO8331 need a separate X20 supply module?
No additional supply module is needed for this output group because the external actuator supply is fed directly to X20DO8331.
What fuse should protect the B&R X20DO8331 field supply?
B&R specifies a maximum 10 A slow-blow line fuse. The complete branch-circuit design must also satisfy local electrical requirements.
Can outputs on B&R X20DO8331 be connected in parallel?
B&R permits parallel connection to increase current, but the channels must be wired and commanded consistently and the group-current and thermal limits still apply.
Why can a B&R X20DO8331 output shut down even below its nominal channel current?
Short-circuit peaks, load inrush, high ambient temperature, insufficient cooling, supply problems, or combined group loading can activate protection.
Which accessories are required for B&R X20DO8331?
Order an X20TB12 terminal block and a compatible X20BM11 or X20BM15 bus module separately.
How should an inductive load be assessed for B&R X20DO8331?
Check steady current, inrush, stored energy, switching frequency, cable length, and the actuator manufacturer's suppression requirements.
What must be recorded before replacing B&R X20DO8331?
Record the direct supply and fuse, sink-output wiring, any parallel channels, load currents, terminal mapping, bus module, diagnostics, and project configuration.
