The ABB PM571 1SAP130100R0100 is a CPU unit in ABB's AC500 series of programmable logic controllers (PLCs). Here is a detailed introduction:
Performance Parameters
Power Supply: It operates on a 24 - VDC power supply.
Memory Capacity: It has a program memory of 64 KB.
Interfaces: It comes with two COM ports. COM1 is of the terminal block type, and COM2 is a nine - pin serial port. The communication protocols of both interfaces can be set to RS232/RS485. COM1 can be expanded to have the CS31 master - station function, supporting Modbus master/slave communication or ASCII functions. COM2 has similar functions.
Network Connectivity: It has integrated Ethernet communication capabilities and supports various field - bus communication expansion function modules.
Expansion Capability: It can be centrally expanded with a maximum of 7 local expansion modules. The maximum number of digital inputs/outputs (DI/DO) is 224 points (for central configuration), and the maximum number of analog inputs/outputs (AI/AO) is 112 points (for central configuration). The maximum number of distributed input/output points depends on the use of the bus.
Operating Speed: The typical operating speed is 0.3 ms per 1000 instructions.
Product Features
Adjustable Communication Rate: It supports the predefined communication rates in the standard specifications and can be manually set to all standard rates or achieve rate auto - adaptation through DIP switches.
Status Indication and Alarm Function: It is equipped with 6 bi - color LED status - indication lights and a power - failure relay - output alarm function.
Industrial - Grade Design: It features industrial - grade designs such as 4000 - V lightning protection for electrical interfaces, 1.5 - A over - current protection, and 600 - W surge protection. It has also passed EMC test certifications.
Power Supply Characteristics: It uses a wide - range redundant dual - power supply of DC9 - 36 V, with DC1500 - V power - supply isolation and reverse - connection protection.
Protection and Installation: It reaches an IP30 protection level, adopts a corrugated aluminum - reinforced casing, and supports the standard industrial 35 - mm rail - mounting method.
