ABB 07KT98C 1MB User Program Controller Original

Product Overview

The ABB 07KT98C (Part Number: GJR5253100R028) functions as the high-capacity central processing core for the Advant Controller 31 (AC31) and Procontic CS31 series. This versatile basic unit executes complex automation programs with a substantial 1 MB user memory capacity. It coordinates 24 integrated digital input channels and manages high-speed counting tasks for precise motion or flow monitoring. We deliver this controller in 100% Brand New and Original factory condition, providing the processing power required for water treatment, power distribution, and advanced manufacturing lines.

Technical Specifications

The 07KT98C architecture prioritizes memory depth and flexible signal acquisition for large-scale industrial applications.

Engineering Advantages

• Extended Memory Capacity: The 1 MB user program and 1 MB data memory allocation allow the 07KT98C to handle significantly larger logic blocks than standard AC31 CPUs. This enables complex data acquisition and sophisticated HMI interactions without compromising cycle times.

• Flexible Digital Input Grouping: This controller organizes its 24 digital inputs into three isolated groups (ZP0, ZP1, ZP2). This electrical isolation prevents cross-interference between different sensor circuits and allows for different reference potentials within a single module.

• Configurable Signal Processing: Integrated optocouplers manage signal coupling for high electromagnetic immunity. Engineers can adjust the input signal delay from the typical 7 ms down to 1 ms, providing the rapid response required for high-speed industrial machinery.

• Dedicated High-Speed Counters: Channels E 62,00 and 62,01 support high-speed pulse counting. This hardware-level integration allows the 07KT98C to track fast-moving encoders or flow meters directly, offloading intensive tasks from the main logic processor.

• Superior Cabling Reach: The 07KT98C supports unshielded cable runs up to 600 m and shielded runs up to 1000 m. This exceptional signal integrity facilitates distributed control across expansive facilities without the need for additional signal repeaters.

FAQs

• Does the 07KT98C GJR5253100R028 require a separate communication board?

  The basic unit includes native support for the CS31 bus and serial communication. However, integration into Profibus or Modbus networks depends on your specific system configuration and may utilize the onboard modular ports for open integration.

• Can I replace an 07KT97 or 07KT92 with this 07KT98C?

  The 07KT98C offers superior memory (1 MB) compared to lower models in the AC31 series. It generally serves as a high-performance upgrade. Always verify your program size and I/O mapping requirements before performing a field swap.

• How does the RETAIN memory function during power loss?

  The 256 kB RETAIN memory stores critical process variables during power cycles. This ensures the controller resumes its exact state upon restart, preventing data loss in continuous processes like water treatment or chemical batching.

• Is this unit 100% Brand New or refurbished?

  We sell only 100% Brand New and Original units in factory packaging. Each 07KT98C carries a unique ABB serial number and a 12-month factory warranty, ensuring it meets all original performance specifications.
