      Information

      Information

      Overview Common Applications Product Precautions
      SDCS-CON-1 is the control board for the ABB DCS500 DC drive family. ABB documents an 80C186 microprocessor and DC94L01 ASIC architecture. The board coordinates drive control, measurement, thyristor firing pulses, supervision, diagnostics and serial communications. Flash PROM devices D33 and D34 retain the system program and parameter values, while D35 stores application functionality and parameters. Static RAM retains fault and alarm messages using a 1 F backup capacitor. The board supports CDP310/CDP311 control panels and configurable internal or external I/O options. Compatibility must be checked by complete converter type, board revision, software, application program and installed option boards.
      Typical DCS500-system applications by industry include: Metals — rolling mills, piercing mills, roller tables and coordinated master-follower sections; Pulp and paper — paper-machine sections, winders and unwinders; Mining — mine-hoist drive systems; Cranes and material handling — hoists, travel drives and conveyor-related motion; Plastics and rubber — extruders and rubber mixers; Wood products and printing — veneer lines and printing-machine sections; Non-motor DC applications — industrial magnets, battery chargers and electrolysis systems. SDCS-CON-1 is the control board inside a compatible DCS500 converter; suitability depends on the complete drive rating, application software, I/O, feedback, field exciter and safety design.
      Qualified personnel only. Isolate all power sources, lock out the converter, wait for DC-link discharge and verify zero energy before handling the board. Use ESD protection. Back up parameters, application software and fault history before removal. Record the complete drive type, frame, board revision, software version, I/O boards, communication modules, field exciter, control panel and connector positions. Do not assume SDCS-CON-2, SDCS-CON-4 or a current-generation board is a direct replacement for SDCS-CON-1. Connector allocation, I/O voltage, communications, software, firing control and application functions may differ. A DCS500 modernization requires an as-installed engineering review, wiring and safety validation, parameter conversion, commissioning tests and confirmation of the selected ABB migration solution.

      Technical notes

      Technical notes

      ABB places the DCS500 family in the obsolete lifecycle phase. SDCS-CON-1 is not a supported drop-in replacement target for a modern control board. Migration normally requires review of the complete drive type and frame, software and parameter backup, application program, I/O boards, field exciter, communications, operator panel, wiring and safety functions. ABB migration guidance points to DCS800/DCS880 solutions depending the installed system and engineering scope.

      FAQS

      • What is the ABB SDCS-CON-1?
        It is the main control board used in the ABB DCS500 DC drive family. It performs drive control, measurement, diagnostics, thyristor firing and communication functions.
      • Which drive family uses SDCS-CON-1?
        ABB identifies SDCS-CON-1 as a DCS500 control board. Compatibility must be confirmed against the complete converter type, board revision, software and installed option boards.
      • Which processor and ASIC are used?
        ABB documentation specifies an 80C186 microprocessor and a DC94L01 ASIC.
      • What communication interfaces are available?
        The board has two RS485 channels: X16:1–3 for field-exciter control and X33/X34 for the CDP310 or CDP311 control panel. PC and serial fieldbus communication require the specified SDCS-COM option.
      • What happens if the internal watchdog trips?
        The programming voltage is forced low, thyristor firing is reset and disabled, digital outputs go low, and programmable analog outputs reset to 0 V.
      • Is the ABB DCS500 family discontinued?
        Yes. ABB lifecycle notices place DCS500/DCS500B in the obsolete phase. Exact availability of SDCS-CON-1 service stock must be confirmed at the time of enquiry.
      • Can SDCS-CON-2 or SDCS-CON-4 directly replace SDCS-CON-1?
        A direct board-level substitution should not be assumed. Different generations have different hardware, connectors, I/O, software and application requirements; ABB migration guidance requires an engineering review.
      • What information is needed before replacement or migration?
        Provide the complete drive nameplate, converter type and frame, SDCS-CON-1 revision, software version, parameter and application backups, I/O and communication boards, field exciter, operator panel, wiring drawings and safety-function details.
