      Information

      Overview Downloads Applications / Compatibility Product Precautions
      • B&R X20AI2222 supports a small pair of voltage measurements where adjustable signal conditioning is more useful than adding unused analog channels.
      Channels: Two bipolar differential measurements
      Data: Signed INT with 2.441 mV increments
      Timing: 300 µs conversion before filter/network effects
      Two differential inputs are converted with 13-bit resolution including sign. Conversion takes 300 µs for both channels, and the process value uses a signed INT representation. One converter increment corresponds to 2.441 mV and a data-word increment of eight.

      The module is designed for a six-pin X20 terminal block, with a twelve-pin block also permitted when needed. It consumes 0.8 W from the internal I/O supply and 0.01 W from the bus; unused inputs should be bridged at the terminal as recommended for lower dissipation.

      When the digital filter is enabled, input sampling occurs at millisecond intervals with a 200 µs offset between channels and asynchronously to the network cycle. Filtering and ramp limiting therefore affect the temporal relationship between a physical input step and its reported value.
      Controller platform reference: X20 two-channel analog acquisition. Match the installed configuration and applicable instructions.
      B&R X20AI2222: original manufacturer technical information covering the specified interfaces and operating limits. Installation topics include: choose the two-channel mapping, verify signal and reference wiring, set the signed conversion scale, apply a known input step, test polarity and channel identity.
      Original manufacturer pages retain their technical context. Use the Apter Power guide with the applicable manufacturer instructions and approved installation design.
      System and supply context: B&R X20AI2222 operates within the following defined system context. Match X20AI2222 and the installed terminal and filtering arrangement.

      Application scope: The applications below describe its technical role. Select associated hardware and configuration for the actual installation.
      Prepare B&R X20AI2222 for its configured installation using these checks.
      Select the terminal block

      Use the intended X20TB06 or permitted X20TB12 arrangement. Compare the actual input pin allocation rather than assuming all terminal positions are active.

      Treat unused inputs correctly

      Bridge any unused input at the terminal according to the applicable wiring guidance. Do not leave its diagnostic state unexplained in the application.

      Review filtered sampling timing

      Allow for millisecond sampling and the 200 µs interchannel offset when comparing changing signals. Avoid assuming simultaneous samples from two matching displayed values.

      Check the minimum filter cycle

      Confirm that the cycle time exceeds 500 µs if the digital filter is required. Resolve a disabled filter through configuration rather than replacing a functioning module.

      Retain the two-input setup

      Save terminal type, used and bridged channels, signed scaling, filter settings and response measurements. These details preserve the intended behavior after future replacement.

      Test polarity and channel identity

      Apply positive, zero and negative values to one channel at a time. Confirm that only the intended signed application variable responds.

      Technical notes

      Operating boundary: A data-word step of eight represents one converter increment. Raw-word arithmetic must account for that representation when comparing resolution with voltage.

      Integration details: Preserve terminal choice, channel reference wiring, signed scaling and filtered-sampling assumptions when replacing X20AI2222.

      Technical basis: B&R X20AI2222 Data Sheet, V1.30. X20AI2222 is the two-input ±10 V module. The 300 µs conversion time does not include every filter and network-cycle contribution.

      FAQ View All FAQ

      • What is the smallest converter increment of X20AI2222?
        One ADC increment is 2.441 mV and appears as an increment of eight in the signed process-data word.
      • Which terminal blocks can be used with X20AI2222?
        The module is designed for X20TB06, while X20TB12 can also be used when required by the installation arrangement.
      • Are filtered measurements from the two channels of X20AI2222 simultaneous?
        No. With filtering enabled, the channel sampling has a 200 µs offset and occurs asynchronously to the network cycle.
      • What sampling interval is used by the enabled digital filter of X20AI2222?
        The channels are sampled at millisecond intervals. This is separate from the 300 µs conversion time for both inputs.
      • Why does X20AI2222 use a signed INT process value?
        The ±10 V measurement range includes both polarities. The signed representation preserves negative as well as positive input values.
      • How should an unused input on X20AI2222 be handled?
        B&R recommends bridging unused inputs at the terminal to reduce power dissipation, following the appropriate terminal wiring arrangement.
      • Can ramp limiting on X20AI2222 operate while its filter is disabled?
        No. Ramp limiting is performed in conjunction with filtering and acts on the input before the filter stage.
      • What happens if the cycle time for X20AI2222 is shorter than the filter's minimum?
        The configurable filter is disabled for cycle times that do not exceed 500 µs. Check the actual cycle before expecting filtered behavior.
