ABB PM564-RP-ETH-AC PLC Automation CPU Module for AC500-eCo Series

Description

The ABB PM564-RP-ETH-AC is a compact, all-in-one PLC automation CPU module from the AC500-eCo series. Designed for cost-sensitive industrial applications, it integrates a 32-bit ARM processor, onboard mixed I/O (6DI/6 Relay DO, 2AI/1AO), and dual communication ports (Ethernet + RS485) in a single DIN-rail unit. The “AC” suffix denotes a wide-range 100–240V AC power supply, making it ideal for direct integration into standard industrial power systems without an external DC power supply. It is widely used in building automation, small machinery, and distributed control systems where space, cost, and ease of installation are critical.

Description

Application Scenarios

In a Taiyuan-based HVAC control system for a commercial building, the ABB PM564-RP-ETH-AC serves as the local controller for an air handling unit (AHU). The module’s onboard 6 digital inputs monitor fan status and filter pressure switches, while the 6 relay outputs directly command the fan contactor, damper actuators, and alarm horn. The integrated 2 analog inputs read temperature and humidity sensors, and the analog output modulates the heating valve. Powered directly from the 220V AC cabinet supply, it eliminates the need for a separate 24V DC power module. The built-in Ethernet port connects the unit to the building’s BMS (Building Management System) via Modbus TCP, providing real-time data monitoring and centralized control.
