More Information

Overview Manuals Loop Wiring Fault Handling Integration Application
  • Acquires eight 0 to 20 mA or 4 to 20 mA differential channels
  • Converts all inputs in one millisecond with 12-bit resolution
  • Includes reverse-polarity protection, supply-wiring protection, and channel diagnostics

X20AI8321 is a B&R analog current input module designed for X20 System I/O stations.

The module concentrates eight process-current loops in one X20 slice while isolating the channel group from the bus.

Before installation or replacement, verify the complete material number, 0 to 20 mA or 4 to 20 mA mode, external loop power, channel polarity, total wiring layout, common-mode voltage, scaling, hardware revision for power data, X20TB1F, X20BM11 or X20BM15, and fault handling.

Availability, condition, price, and shipping time for X20AI8321 are confirmed during quotation.

  • External transmitter or loop power is required where the field device needs it
  • Each current loop must be wired with correct polarity and common reference
  • The X20TB1F 16-pin terminal block is required for the eight-channel layout
  • Reverse-polarity protection helps protect incorrectly connected current loops
  • The controller can receive a configurable digital value during overload
  • Open-loop and under-range behavior should be defined in the application for 4 to 20 milliamp signals
  • The input group is isolated from the bus but channels are not isolated from one another
  • Hardware revision D0 changes the documented internal I/O power value
  • Scaling, alarms, and transmitter fault thresholds are configured in the controller project
  • Eight-channel 4 to 20 mA process-transmitter acquisition
  • High-density 0 to 20 mA measurement in distributed X20 I/O
  • Multi-sensor current-loop monitoring in machine and process-control stations
Description
X20AI8321 is a B&R analog current input module for the X20 System distributed I/O platform.

It acquires eight differential current channels in one millisecond, provides reverse-polarity and supply-wiring protection, and supports software-visible diagnostics.

Before installation or replacement, confirm the complete material number, 0 to 20 mA or 4 to 20 mA mode, external loop power, channel polarity, total wiring layout, common-mode voltage, scaling, hardware revision for power data, X20TB1F, X20BM11 or X20BM15, and fault handling.

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 X20AI8321 supply power to connected transmitters?
No transmitter supply is specified. Provide appropriate external loop power and verify the complete loop wiring and common reference.
How should a broken 4 to 20 mA loop be detected with B&R X20AI8321?
Configure scaling and under-range diagnostics in the controller so that a low current is distinguished from a legitimate process value.
Are all B&R X20AI8321 channels isolated from one another?
No. The eight-channel group is isolated from the bus, but individual channels are not isolated from each other.
Why should the hardware revision of B&R X20AI8321 be recorded?
B&R lists different internal I/O power values before and from revision D0, which can matter in station power calculations.
What should be checked when B&R X20AI8321 reports overload?
Inspect loop polarity, transmitter supply, current level, common-mode voltage, terminal mapping, shorts, and configured overload behavior.
Which terminal block is required for B&R X20AI8321?
Use the documented X20TB1F 16-pin terminal block with a compatible X20BM11 or X20BM15 bus module.
What should be saved before replacing B&R X20AI8321?
Record hardware revision, channel ranges, loop supplies, polarity, scaling, alarm thresholds, terminal mapping, accessories, and Automation Studio configuration.
