ABB PM573 1SAP130100R0100 central processing unit

Product Overview

The ABB PM573-ETH (1SAP130300R0271) is a performance-oriented central processing unit within the AC500 PLC family, specifically designed for applications requiring high-speed logic and native networking. With 512 kB of program memory, it handles significantly larger and more complex automation tasks than the entry-level PM571 series.

Engineering & Network Advantages

The PM573-ETH serves as a powerful hub for distributed control:

• High-Speed Connectivity: The integrated Ethernet port allows for high-speed peer-to-peer communication between PLCs and provides a direct path for SCADA or HMI integration without needing extra cards.

• Advanced Instruction Set: Its ability to process floating-point math at high speeds makes it suitable for complex PID control and mathematical modeling in process automation.

• Scalable Modular Design: While powerful on its own, it can manage a vast local I/O network (up to 320 digital inputs) and communicate across multiple fieldbuses simultaneously using expansion couplers.

• Battery-Free Operation: The program is stored in non-volatile flash memory. However, an optional battery can be added to the terminal base to retain real-time clock (RTC) data and persistent variables.
