      Overview Manuals Common Applications Product Precautions
      B&R X20AT2222 measures two Pt100 or Pt1000 resistance-temperature channels with internal linearization and configurable filtering. Each channel supports direct 2-wire or 3-wire sensor connection for X20 temperature acquisition.
      • Linearizes two resistance-temperature channels inside the module
      • Lets each channel select Pt100 or Pt1000 independently
      • Flags open circuits and range faults through defined diagnostic values
      • Adapts measurement response with a configurable digital filter

      Wire B&R X20AT2222 with the selected 2-wire or 3-wire scheme and set the sensor type independently for each channel. Verify lead resistance, open-circuit diagnostics, filter time and a controlled temperature point before acceptance.

      Important Notice: Confirm B&R X20AT2222, terminal hardware, field wiring, installed accessories and current B&R documentation before commissioning.

      Machine bearing temperature
      B&R X20AT2222 converts two installed RTDs into controller temperature values for monitoring.
      Heater-zone feedback
      Independent sensor selection supports two Pt100 or Pt1000 control points in an X20 station.
      Process skid RTD acquisition
      Two- or three-wire connections accommodate documented field-sensor wiring.
      Temperature diagnostic retrofit
      Open-circuit and range codes help distinguish wiring faults from valid process temperatures.
      Read the applicable B&R instructions before work. Verify B&R X20AT2222 and the installed X20 System configuration.
      1
      Verify X20AT2222 and both RTD channel assignments before disconnecting sensors.
      2
      Record whether each channel is configured for Pt100 or Pt1000.
      3
      Preserve the selected 2-wire or 3-wire wiring method and terminal numbering.
      4
      Use X20TB06 or X20TB12 with X20BM11 or X20BM15 as documented.
      5
      Route low-level RTD conductors away from switching and motor cables.
      6
      Set the filter time for the required response and mains-noise rejection.
      7
      Check open-circuit and range diagnostic behavior before enabling temperature interlocks.
      8
      Compare both channels with a traceable resistance or temperature reference after installation.

      FAQS

      • Can B&R X20AT2222 mix Pt100 and Pt1000 sensors on the same module?
        Yes. B&R states that the sensor type is configurable per channel, so the two channels can be assigned independently.
      • Which wiring methods are accepted by B&R X20AT2222?
        The module performs constant-current resistance measurement with either 2-wire or 3-wire connections.
      • How does B&R X20AT2222 report an open Pt sensor circuit?
        For temperature measurement it returns 0x7FFF; the resistance-measurement format uses 0xFFFF.
      • What temperature span is linearized inside B&R X20AT2222?
        Both Pt100 and Pt1000 are normalized from -200.0 to 850.0 C according to EN 60751.
      • Which filter adjustment controls B&R X20AT2222 response time?
        The filter time is configurable from 1 ms to 66.7 ms, allowing the project to balance noise rejection and response.
      • How long does B&R X20AT2222 need for two channels with a 50 Hz filter?
        The official data lists 80 ms conversion time for two channels, compared with 20 ms for one channel.
      • What resistance ranges are available from B&R X20AT2222?
        Gain 1 covers 0.1 to 4500 ohm and gain 2 covers 0.05 to 2250 ohm.
      • How should B&R X20AT2222 channel accuracy be checked after rewiring?
        Apply traceable resistance values to each configured channel, confirm the 0.1 C resolution, and verify that open-circuit and overrange diagnostics operate correctly.
