More Information

Overview Manuals Load Derating Expansion Limits Protection Application
  • Supplies smaller X20 bus-controller systems
  • Uses a non-isolated BC/X2X feed
  • Requires load derating and does not support supply redundancy

X20PS9402 is a B&R non-isolated bus controller power supply module designed for the X20 System.

The module provides a compact supply solution for smaller compatible X20 bus-controller stations where the documented derated output is sufficient and expansion or redundancy is not required.

Before installation or replacement, verify the complete material number, small-station power budget, mounting-orientation derating, non-isolated BC/X2X feed, prohibition on parallel and redundant operation, prohibition on bus-transmitter expansion, I/O line fuse, bus base, X20TB12, and potential groups.

Availability, condition, price, and shipping time for X20PS9402 are confirmed during quotation.

  • Available BC/X2X output depends on mounting orientation and temperature
  • Horizontal and vertical limits are different
  • The design must retain margin under worst-case cabinet conditions
  • Parallel operation is not permitted
  • Redundant operation is not permitted
  • Expansion with a bus transmitter is not permitted
  • Separate I/O potential groups can be formed
  • The I/O input requires a maximum 10 ampere slow-blow fuse
  • The I/O input is not reverse-polarity protected
  • Small X20 bus-controller stations
  • Cost-sensitive stations without BC/X2X redundancy
  • Compact systems whose worst-case load fits the documented derating curve
Description
X20PS9402 is a B&R non-isolated bus controller power supply module for the X20 System.

It feeds the bus controller, X2X Link, and internal I/O without galvanic isolation of the BC/X2X supply and does not permit parallel, redundant, or bus-transmitter expansion of that supply.

Before installation or replacement, confirm the complete material number, small-station power budget, mounting-orientation derating, non-isolated BC/X2X feed, prohibition on parallel and redundant operation, prohibition on bus-transmitter expansion, I/O line fuse, bus base, X20TB12, and potential groups.

Technical notes
X20PS9402 is intended for smaller X20 bus-controller stations. Its BC/X2X supply is not galvanically isolated and cannot be expanded or made redundant by parallel supply modules; verify temperature-dependent output power, mounting orientation, load, accessories, and I/O protection.

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 decide whether B&R X20PS9402 has enough capacity?
Calculate the complete bus-controller and X2X load at the worst cabinet temperature and mounting orientation, then compare it with the documented 7 W and 5 W derated limits.
Can B&R X20PS9402 be paralleled for more X2X power?
No. Parallel and redundant operation are not permitted, and the module cannot be expanded through a bus transmitter.
When should B&R X20PS9400 be used instead of X20PS9402?
Use X20PS9400 when isolation, BC/X2X supply redundancy, parallel operation, RS232 service access, or a different expansion concept is required.
Why can B&R X20PS9402 work when cool but fault in a hot cabinet?
Available BC/X2X output is temperature- and orientation-dependent, so a load near the limit can exceed the derated capacity as cabinet temperature rises.
Can B&R X20PS9402 create separate I/O potential groups?
Yes, potential groups can be formed, but the BC/X2X supply itself cannot be expanded or made redundant by another supply module.
Which accessories are required with B&R X20PS9402?
Use the applicable X20BB80, X20BB81, or X20BB82 bus base and X20TB12 terminal block, ordered separately.
What should be documented before replacing B&R X20PS9402?
Record mounting orientation, cabinet temperature, BC/X2X and I/O loads, both feeds, fuse, potential groups, bus base, terminal block, controller, and diagnostics.
