More Information

Overview Manuals Sensor Setup Fault Values Timing Application
  • Measures two Pt100 or Pt1000 resistance-temperature channels
  • Supports direct resistance measurement with 16-bit sigma-delta conversion
  • Provides configurable filtering and explicit open-circuit fault values

X20AT2222 is a B&R temperature input module designed for X20 System I/O stations.

The module converts two resistance-temperature channels into controller values while allowing sensor type selection per channel and a module-level choice of 2- or 3-wire connection.

Before installation or replacement, verify the complete material number, Pt100 or Pt1000 selection, the module-level 2- or 3-wire mode, lead resistance, filter time, conversion timing, scaling, X20TB06 or X20TB12, X20BM11 or X20BM15, and fault-value handling.

Availability, condition, price, and shipping time for X20AT2222 are confirmed during quotation.

  • Pt100 or Pt1000 sensor type is configured independently for each channel
  • The choice between 2-wire and 3-wire connection is configured for the complete module
  • Internal linearization follows the documented EN 60751 characteristic
  • An open temperature input is reported with the documented 0x7FFF value
  • An open resistance-measurement input is reported with the documented 0xFFFF value
  • Range and general-fault values must be handled explicitly in controller logic
  • Filter time is configurable from 1 to 66.7 milliseconds
  • One enabled channel converts faster than two channels with the 50 hertz filter
  • Required response time and noise rejection should be balanced during configuration
  • Two-channel Pt100 temperature acquisition in X20 stations
  • Pt1000 process-temperature measurement in distributed I/O
  • Direct resistance measurement in machine and process-control systems
Description
X20AT2222 is a B&R temperature input module for the X20 System distributed I/O platform.

It measures Pt100, Pt1000, or direct resistance signals with 16-bit sigma-delta conversion, internal linearization, configurable filtering, and open-circuit monitoring.

Before installation or replacement, confirm the complete material number, Pt100 or Pt1000 selection, the module-level 2- or 3-wire mode, lead resistance, filter time, conversion timing, scaling, X20TB06 or X20TB12, X20BM11 or X20BM15, and fault-value handling.

Technical notes
X20AT2222 selects Pt100 or Pt1000 per channel but configures 2- or 3-wire mode for the complete module; verify sensor wiring, lead resistance, filter time, scaling, X20TB06 or X20TB12, and fault handling before replacement.

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.
Can B&R X20AT2222 use one Pt100 and one Pt1000 sensor?
Yes. Sensor type is configurable per channel, so each channel can use the documented Pt100 or Pt1000 selection.
Can B&R X20AT2222 mix 2-wire and 3-wire sensors?
The wiring mode is configured for the complete module, not independently per channel, so both inputs must follow the validated module-level arrangement.
How does B&R X20AT2222 report a broken sensor wire?
The module returns the documented open-circuit fault value, which the controller logic should distinguish from valid temperature or resistance data.
How should lead resistance be handled with B&R X20AT2222?
Use the documented wiring method and validate conductor resistance and symmetry; 3-wire connection is typically used when lead compensation is required.
Why does B&R X20AT2222 response time change with configuration?
Conversion time depends on enabled-channel count and filter setting, so noise rejection and required process response must be balanced.
Which terminal blocks can be used with B&R X20AT2222?
B&R documents X20TB06 or X20TB12, together with an X20BM11 or X20BM15 bus module.
What should be saved before replacing B&R X20AT2222?
Record each sensor type, the module wiring mode, filter time, scaling, fault-value handling, terminal mapping, accessories, and Automation Studio configuration.
