ABB PM590-ARCNET Processor Module

Description

The ABB PM590-ARCNET Processor Module (product number 1SAP150000R0261) is a high-performance CPU unit designed for the ABB AC500 PLC series, a flexible, cost-effective control system launched in 2005. Key technical specifications include 2MB of program memory, 24VDC power supply, and multiple communication interfaces: ARCNET, 2x configurable RS232/485 ports, and FBP, with an integrated display for local status monitoring.

This module supports rich communication functions: each RS232/485 port offers programming capability, CS31 master station function, Modbus master/slave communication, and ASCII function, while the integrated ARCNET interface enables reliable industrial network connectivity. It features flexible expansion capacity, supporting up to 7 local expansion modules with a maximum of 224 digital input/output (DI/DO) points and 112 analog input/output (AI/AO) points in centralized configurations; distributed I/O capacity varies based on bus usage. The AC500 series uses PS501 configuration software and is compatible with third-party human-machine monitoring software, as it does not include native HMI software. The module holds CE, BV, and GL product certifications, making it suitable for a wide range of industrial automation control applications.
