      Information

      Information

      Overview Manuals Common Applications Product Precautions
      B&R X20DO4529 provides four individually isolated relay changeover outputs for 30 VDC or 115 VAC control circuits. It connects discrete field loads to an X20 station while keeping each output channel isolated from the other channels and the bus.
      • Switches four independent field circuits with changeover contacts
      • Separates each relay channel from the remaining outputs and the X20 bus
      • Reports module and output status through LEDs and software diagnostics
      • Supports DC and mains-frequency AC control duties with external load suppression

      Install B&R X20DO4529 with an X20TB12 terminal block and X20BM11 or X20BM15 bus module. Select external suppression for AC or DC loads and prove every relay channel against the configured output state before release.

      Important Notice: Confirm B&R X20DO4529, terminal hardware, field wiring, installed accessories and current B&R documentation before commissioning.

      Important Notice: The first document is an Apter Power model-specific technical reference; the second is the B&R official data sheet identified in the manufacturer source record.

      Isolated interposing relay duties
      B&R X20DO4529 separates four commanded loads where each circuit needs its own changeover contact.
      Valve and contactor command
      The module switches documented DC or AC control coils through externally protected relay contacts.
      Mixed-potential panel outputs
      Single-channel isolation permits independent field circuits within the approved voltage limits.
      X20 machine-control stations
      Status LEDs and software diagnostics support output commissioning and maintenance in an X20 node.
      Read the applicable B&R instructions before work. Verify B&R X20DO4529 and the installed X20 System configuration.
      1
      Confirm the complete X20DO4529 marking and the assigned four output circuits before work.
      2
      Isolate every external field voltage because the relay circuits can carry potentials independent of the X20 bus.
      3
      Use X20TB12 with X20BM11 or X20BM15 and verify terminal coding before insertion.
      4
      Keep each load within the documented voltage, current and switching-capacity limits.
      5
      Fit an RC network or VDR on AC inductive loads and an inverse diode, RC network or VDR on DC inductive loads.
      6
      Do not rely on internal contact suppression because X20DO4529 provides none.
      7
      Record contact state and field voltage on all four channels during controlled commissioning.
      8
      Prove safe de-energization and the expected changeover action before returning the machine to service.

      Install B&R X20DO4529 with an X20TB12 terminal block and X20BM11 or X20BM15 bus module. Select external suppression for AC or DC loads and prove every relay channel against the configured output state before release.

      FAQS

      • How are the four B&R X20DO4529 relay channels electrically separated?
        B&R specifies each channel as isolated from the other channels, the bus and the I/O power supply.
      • Which loads fit the B&R X20DO4529 nominal contact ratings?
        The documented nominal ratings are 1 A at 30 VDC and 0.5 A at 115 VAC, subject to the stated switching-capacity limits.
      • What external suppression is required when B&R X20DO4529 switches an inductive load?
        For AC loads use an RC combination or VDR; for DC loads use an inverse diode, RC combination or VDR.
      • Why must a B&R X20DO4529 replacement retain the terminal and bus modules?
        The official data sheet requires an X20TB12 terminal block and an X20BM11 or X20BM15 bus module for the installed slice.
      • How quickly should B&R X20DO4529 contacts change state?
        Both the 0-to-1 and 1-to-0 switching delays are specified at no more than 4 ms.
      • Which contact-life records matter for B&R X20DO4529 maintenance?
        B&R lists at least 100,000 electrical operations and 50 million mechanical operations at 3 Hz; the actual load history remains important.
      • What diagnostics can confirm a commanded B&R X20DO4529 output?
        The module provides per-output LED indication plus operating-state and module-status reporting.
      • How should B&R X20DO4529 be accepted after wiring changes?
        Energize each documented field circuit under controlled conditions, compare the command with contact state and prove the intended safe state on de-energization.
