AEG 411 02/110CPU41102

Product Introduction:
The AEG 411 02/110CPU41102 is a high-performance CPU module from the Modicon Quantum platform, specifically the 411 series with 110V AC power supply. It is designed for medium-to-large scale process automation and discrete manufacturing applications requiring high-speed processing, large memory capacity, and extensive I/O handling. This CPU serves as the central processing unit of a Quantum PLC rack, executing user programs, managing I/O communication, and handling network traffic.

Working Principle:
The CPU 41102 executes the user application program in a continuous scan cycle. Each cycle consists of: (1) Input scan — reading states from all connected I/O modules via the Quantum backplane bus; (2) Program execution — processing logic, math, motion, and communication tasks; (3) Output scan — writing results to output I/O modules; (4) Communication handling — processing network requests from Ethernet, Modbus Plus, and serial ports. The RISC processor executes instructions from on-chip cache for maximum speed, while the communication coprocessor handles network traffic independently.

  • Integrated Motion: Up to 4-axis positioning without external motion controller
  • Robust Design: Industrial temperature range, EMI shielding, battery-backed memory

Applicable Industries:

  • Oil and gas (upstream, midstream, downstream)
  • Chemical and petrochemical processing
  • Power generation (thermal, hydro, nuclear auxiliary)
  • Water and wastewater treatment
  • Pulp and paper manufacturing
  • Mining and minerals processing
  • Pharmaceutical manufacturing

Installation Requirements:

  • Install in Quantum PLC chassis (e.g., Quantum 65-786-0100, 65-786-0200, or 65-786-0400)
  • Ensure 110V AC power supply is stable (±15% tolerance)
  • Use Quantum-certified I/O modules only
  • Connect Ethernet cables to dedicated network switch (not daisy-chained)
  • Install Modbus Plus terminators at both ends of the segment (110 Ω)
  • Ground the PLC chassis to protective earth

Usage Precautions:

  • Do not insert or remove modules with power applied (hot-swap not supported for CPU)
  • Replace battery within 10 years to prevent data loss
  • Do not exceed maximum I/O configuration (4096 points)
  • Use surge protection on 110V AC power input
  • Maintain firmware version consistency across all modules in the rack
