      Information

      Overview Downloads Applications / Compatibility Product Precautions
      • B&R X20AI4632 captures four signals in the same 50 microsecond conversion interval, helping keep related process measurements aligned in time.
      Analog channels: 4 differential inputs
      Voltage range: +/-10 V
      Current range: 0 to 20 mA
      Each channel has separate current and voltage input terminals with a common negative input. Selection therefore depends on the field connection as well as the application configuration; the X20TB12 terminal block carries all four channels.

      The SAR conversion produces signed voltage data and nonnegative current data. Per-channel filtering and user scaling adapt the acquired values to the application, while configurable limit analysis and trace functions support signal examination.

      Inputs are isolated from the bus but not from one another. Observe the +/-12 V common-mode range and separate this module from the listed controller, bus-receiver and supply modules by at least one module to reduce disturbance.
      Controller platform reference: B&R Analog Input Module. Use the applicable installation instructions.
      Original B&R technical material applicable to X20AI4632, covering function, interfaces and operating limits. Installation topics include: map all four analog channels, protect measurement quality, restore filtering and scaling.
      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: The analog input module is applied in the Four transmitters / Differential inputs / SAR conversion / X20 process values arrangement. Select associated equipment for the actual channel or installation.

      Application scope: The technical values apply to this model in the specified installation and configuration. The examples below address the stated product function.
      Prepare B&R X20AI4632 for its configured installation using these checks.
      Record voltage and current terminals

      Identify each transmitter and its positive voltage or current terminal.

      Preserve shared reference conditions

      Measure relevant field potentials before reconnecting.

      Allow spacing from noisy modules

      Compare the station order with the connection guidance.

      Terminate unused channels correctly

      Check which channels are unused and apply the recommended bridge or current configuration to reduce dissipation.

      Reapply individual input filters

      Restore the filter assigned to each channel rather than copying one setting across all four.

      Confirm engineering-unit conversion

      Apply a known input within the selected range and compare raw INT data with the scaled engineering value.

      Technical notes

      Preserve shared reference conditions: Measure relevant field potentials before reconnecting. The module has bus isolation but no channel-to-channel isolation, and the common-mode range is +/-12 V; separate isolated transmitters do not make the input channels independently isolated.

      Reapply individual input filters: Restore the filter assigned to each channel rather than copying one setting across all four. Fast transients and slowly varying process signals can need different filtering even when their electrical ranges are the same.

      Review limit and overload behavior: Exercise the configured threshold with a controlled signal and verify the intended application response. Distinguish user-defined limit events from converter range overshoot and synchronization errors before returning the inputs to control.

      FAQ View All FAQ

      • Are the four X20AI4632 channels converted one after another?
        All four inputs are converted within a 50 microsecond conversion interval, supporting simultaneous signal acquisition.
      • How is current input selected on X20AI4632?
        Wire the signal to the current-input terminal rather than the voltage-input terminal and use the corresponding channel settings. The two signal types use different positive terminals.
      • What loading does X20AI4632 present to a voltage transmitter?
        Voltage input impedance is 20 megohms within the signal range. Confirm the source and common-mode conditions as well as the nominal signal amplitude.
      • Can X20AI4632 isolate one field transmitter from another?
        No. The channels are isolated from the bus but not from each other, so inter-channel potential differences must stay within the permitted common-mode range.
      • Why should unused X20AI4632 inputs be bridged or configured for current?
        This reduces internal power dissipation. Apply the method appropriate to the unused terminal arrangement and keep inactive channels out of process calculations.
      • Does an open input always produce an open-line indication on X20AI4632?
        Open-line detection is available for voltage measurement only. A zero current reading cannot automatically be interpreted as a detected cable break.
      • What can the trace function on X20AI4632 record?
        It records sampled analog values for signal analysis. Select the sampling, trigger and record settings appropriate to the event being investigated.
      • Why is module spacing relevant when installing X20AI4632?
        At least one module must separate it from the specified controller, X20BR9300 and listed X20 supply modules to prevent disturbances in the analog measurement.
