- Measures four 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
X20AT4222 is a B&R temperature input module designed for X20 System I/O stations.
The module converts four resistance-temperature channels into controller values while allowing sensor type selection per channel and a module-level choice of 2- or 3-wire connection mode.
Before installation or replacement, verify the complete material number, Pt100 or Pt1000 sensor type, 2- or 3-wire mode, lead resistance, filter time, conversion timing, scaling, terminal and bus modules, and grounding.
Availability, condition, price, and shipping time for X20AT4222 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 sensor 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 the controller application
- Filter time is configurable from 1 to 66.7 milliseconds
- Conversion time depends on the number of enabled channels and the selected filter
- Unused channels and response-time requirements should be considered when configuring acquisition
- Pt100 temperature acquisition in X20 machine-control stations
- Pt1000 process-temperature measurement in distributed I/O systems
- Direct resistance measurement in standard fieldbus control applications
