ABB PM590-ETH Processor Module

Description

The ABB PM590-ETH Processor Module is a programmable logic controller (PLC) module belonging to the AC500 series, designed for industrial automation and process control applications. It features an ARM Cortex-M3 CPU with a 72 MHz clock speed, paired with 256 KB flash memory and 32 KB SRAM to support program storage and real-time data processing. The module is equipped with multiple communication interfaces, including an Ethernet port, RS-485 serial port, and USB interface, enabling flexible connectivity with other devices and systems. It also integrates 20 digital inputs and 16 digital outputs for direct interaction with field devices, and operates on a 24 VDC power supply, with a wide operating temperature range of -25 degrees Celsius to 55 degrees Celsius for stable performance in extreme environments. Key features include high reliability for complex control systems, strong expandability that supports up to 7 local expansion modules, with a maximum of 224 centralized digital input/output points and 112 centralized analog input/output points, and distributed I/O capacity dependent on bus usage. This module is widely applied in utility sectors such as power generation, heating, and water treatment, as well as general industrial automation systems, to enable precise control and monitoring of equipment and processes.
