ABB PM571 1SAP130100R0100 B1 AC500 PLC Processor Module with TA524 Accessory

Product Overview

The ABB PM571 (1SAP130100R0100 B1) serves as a reliable central processing unit for the AC500 modular PLC platform. This CPU manages entry-to-mid-level automation tasks with 64kB of program memory, providing deterministic logic execution for decentralized I/O clusters. This specific package includes the ABB TA524 accessory, ensuring a complete and secure installation for your control architecture. We supply this unit as 100% Brand New and Original, maintaining factory-sealed standards to guarantee maximum uptime in your industrial environment.

Technical Specifications

The PM571 B1 balances computational efficiency with a compact modular design:

• Article Number: 1SAP130100R0100 (Revision B1)

• Program Memory: 64 kB

• User Data Memory: RAM-based architecture for rapid variable access

• Included Accessory: ABB TA524 (Dummy module/cover or specific interface accessory)

• Supply Voltage: 24 V DC (via Terminal Base)

• Internal Interfaces: Supports connection for communication couplers and I/O modules

• Diagnostic Display: Integrated LCD for real-time status monitoring

• Protection Rating: IP20

• Net Width: 67.5 mm

Engineering Advantages

• Optimized Memory Management: The 64kB program memory efficiently handles standard logic sequences, PID loops, and arithmetic functions. This makes the PM571 a cost-effective solution for small-scale machinery and localized process control.

• Integrated Diagnostic LCD: The front-facing display provides immediate feedback on CPU status and error codes. Maintenance teams identify faults directly at the cabinet, bypassing the need for a laptop connection during initial troubleshooting.

• High-Speed Local Bus: The processor manages data exchange across the local I/O bus with minimal latency. It supports the attachment of multiple S500 expansion modules, allowing the system to scale according to your specific I/O requirements.

• Rugged Hardware Revision B1: The B1 hardware revision incorporates optimized internal circuitry for enhanced electromagnetic compatibility (EMC). This ensures stable operation even in electrically noisy industrial environments.

• Modular Flexibility: The CPU seats into a standard Terminal Base (TB5xx), allowing for rapid hardware swaps. This modularity reduces downtime during maintenance cycles as field wiring remains undisturbed on the base.

FAQs

• Does the PM571 require a specific Terminal Base?

  Yes. You must install the PM571 on an ABB AC500 Terminal Base, such as the TB511 or TB521. The base provides the 24V DC power connection and the mechanical interface for the DIN rail.

• What is the function of the included TA524?

  The TA524 typically serves as a dummy module or a protective cover for unused slots on the terminal base or communication coupler positions. It maintains the IP20 rating and protects internal bus connectors from dust and debris.

• Can I expand the communication capabilities of this CPU?

  The PM571 supports additional communication couplers (e.g., PROFIBUS, PROFINET, or CANopen). You plug these couplers into the left side of the terminal base to expand the CPU’s networking reach.

• Is this CPU compatible with the older AC500 software versions?

  The PM571 B1 works seamlessly with the ABB Automation Builder software suite. We recommend using the latest service pack to ensure full access to all diagnostic and configuration features of the B1 hardware revision.
