PM862K01 3BSE076940R1 ABB Programmable logic controller (PLC) CPU
module
ABB PM862K01 (Model: 3BSE076940R1) is a high-performance CPU module
for ABB AC 800M series programmable logic controllers (PLCS),
specifically designed for medium and large-scale industrial
automation and process control applications. As the core processing
unit of the AC 800M system, PM862K01 offers powerful computing
capabilities, large-capacity memory and rich communication
interfaces, supporting complex control logic, high-speed I/O
processing and seamless integration with DCS/SCADA systems.
This module is widely applied in critical industrial scenarios such
as power, oil and gas, chemical engineering, water treatment,
papermaking, and metallurgy, where extremely high requirements are
placed on system stability, security, and scalability.
