Product Features and Technical Specifications

Product Positioning and Core Functions

Model and Series: This product belongs to the ABB AC 800M controller series and is positioned as a redundant processor unit kit.

Redundant design: Supports dual-machine hot backup, the main and standby processors can automatically switch, and the switching time is as short as milliseconds in case of failure, ensuring continuous operation of the system. At the same time, built-in real-time clock and memory backup battery prevent data loss caused by power failure. ABB PM645B Processor Module for Industrial Automation Control Systems

High reliability: With watchdog function, it can monitor the system operation status and automatically restart or switch to the backup processor when abnormal. In addition, the product complies with the EN50082 EMC standard and adapts to 0-60°C operating temperature and -40-70°C storage temperature.

Flexible scalability: Through the CEX bus and ModuleBus interface, it can connect ABB S800 I/O modules and communication modules such as Profibus and Modbus, support hot plugging, and facilitate maintenance and upgrades. Allen-Bradley 1756-IF16/A, ControlLogix 16 Point Analog Input/Output Module

Powerful processing capability: The CPU has strong performance, with a main frequency of 96MHz (some materials mention 350kHz, which may vary depending on the model or configuration), equipped with 32MB RAM (23.522MB available) and 2MB Flash PROM to meet the needs of complex control logic.
