      Information

      Overview Downloads Applications / Compatibility Product Precautions
      • B&R X20DC2395 shares its terminal resources between several motion and pulse functions, allowing one station position to handle a selected mixture of input and output tasks.
      Digital channels: 4 inputs, 2 also configurable as outputs
      Incremental input: 24 V asymmetrical; up to 100 kHz
      SSI interface: 1 encoder; up to 125 kbit/s
      The four channels can serve one SSI absolute encoder, one ABR incremental encoder, two AB encoders or four event counters. Two channels can additionally operate as outputs; the maximum counts describe alternative allocations, not independent simultaneous capacities.

      Incremental inputs accept 24 V asymmetrical signals at up to 100 kHz. SSI uses Gray or binary coding at up to 125 kbit/s. The module-internal encoder supply provides up to 600 mA and is protected against short circuit and overload.

      The two outputs support push, pull or push-pull operation at 0.1 A each. Input edge events can control outputs directly; preserve the channel allocation, pulse period and electrical load before restoring an event-driven machine function.
      Controller platform reference: B&R Counter Module. Use the applicable installation instructions.
      Original B&R technical material applicable to X20DC2395, covering function, interfaces and operating limits. Installation topics include: channel count checks, ssi coding checks, output current checks.
      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 counter module is applied in the Encoder or pulse / Shared input channels / Counter/time engine / X20 data or PWM arrangement. Select associated equipment for the actual channel or installation.

      Application scope: Maximum encoder, counter and PWM counts are alternative allocations of shared terminals. The examples below address the stated product function.
      Prepare B&R X20DC2395 for its configured installation using these checks.
      Allocate the four shared channels

      Draw the installed channel map before changing the module.

      Check the encoder electrical level

      Confirm 24 V asymmetrical encoder signals rather than assuming a differential line-driver interface.

      Set SSI word interpretation

      Retain the selected Gray or binary coding, word length and clock settings.

      Preserve incremental direction

      Mark A, B and reference signals before disconnecting.

      Limit the output load

      Check each output against its 0.1 A nominal rating and the 0.2 A total.

      Inspect PWM timing

      Verify the configured period and duty with a suitable instrument at the output.

      Alternative Names

      Technical notes

      Check the encoder electrical level: Confirm 24 V asymmetrical encoder signals rather than assuming a differential line-driver interface. Record the encoder supply loading and leave the machine unable to move while the pulse wiring is disturbed.

      Limit the output load: Check each output against its 0.1 A nominal rating and the 0.2 A total. Restore the push, pull or push-pull selection only after confirming the connected load and reference wiring.

      Release the assigned functions: Record the accepted encoder positions, pulse counts, output waveform and timing scale for the functions actually used. Keep unused shared channels in their intended configuration before re-enabling motion.

      FAQ View All FAQ

      • Can X20DC2395 run four event counters and two independent PWM channels at once?
        The functions share four physical channels, and two channels can be outputs. A mixed arrangement must respect the terminal allocation; the maximum function counts are not additive.
      • Which absolute encoder formats can X20DC2395 read?
        The SSI interface accepts Gray or binary coding with a 32-bit counter size and a maximum transfer rate of 125 kbit/s.
      • What is the incremental encoder frequency limit of X20DC2395?
        The 24 V asymmetrical incremental inputs support up to 100 kHz with fourfold evaluation.
      • How much current can the two X20DC2395 outputs supply?
        Each output is rated 0.1 A, with 0.2 A total nominal output current. The actual load and switching conditions must also meet the output limits.
      • What PWM timing range does X20DC2395 support?
        The period can be set from 41.6 microseconds to 1.36 seconds, with pulse duration from 0 to 100% and 0.1% duty resolution.
      • Can an input event operate a X20DC2395 output without a normal application write?
        Yes. Output setting and clearing can be controlled by events as well as by the application, provided that the selected channel functions are configured consistently.
      • Which timing quantities can X20DC2395 measure?
        Its timing functions include gate time, period duration and edge offsets between channels, with continuous or triggered measurement.
      • Why must all X20DC2395 signal cables be shielded?
        Shielded signal wiring is required for the counter and encoder interfaces. Preserve the shield arrangement to avoid false edges or corrupted encoder acquisition.
