Schneider AEG 110CPU51202
1. Overview
The 110CPU51202 belongs to the 110-CPU series of the Modicon Micro product line. It is a micro Programmable Logic Controller (PLC) CPU powered by 24 V DC. This module is compatible with all I/O expansion cards of Modicon Micro and can operate in standalone or redundant (hot standby) mode, suitable for scenarios such as discrete control, process control and small-scale motion control.
2. Technical Specifications
Model: 110CPU51202 (also marked as 110-CPU-512-02)Supply Voltage: 24 V DC (±10 %)Operating Temperature: 0 °C – +55 °C (Industrial Grade)Storage Capacity: Approximately 64 KB program memory, 8 KB data memoryCommunication Interfaces: RS-485 (Modbus RTU/ASCII), optional Ethernet expansion moduleScan Cycle: Minimum 1 ms (depending on program complexity)Dimensions: 19-inch rack, 2U width (approx. 88 mm)Certifications: CE, UL, CSA, ISO 9001
3. Product Features
Compact & Reliable: 2U rack size, ideal for control cabinets with limited space.High Compatibility: Supports the full range of Modicon Micro I/O cards (digital, analog, counting, temperature, etc.) for flexible expansion.Easy Programming: Works with Schneider EcoStruxure Control (formerly Unity Pro) software, enabling offline editing, simulation and downloading in Windows environment.Redundancy Support: Can form a hot standby system with the same model CPU to enhance system availability.Multi-protocol Communication: Built-in RS-485; supports access to industrial networks like Modbus, Profibus and Ethernet/IP with corresponding communication modules.Industrial-grade Protection: Complies with IEC 60730 standard, resistant to
electromagnetic interference and vibration, suitable for harsh industrial environments.
4. Structure & Components
CPU Motherboard: Core processing unit integrating CPU, storage and communication interfaces.Power Interface: 24 V DC input terminal with overvoltage and undervoltage protection.System Bus: Backplane bus (Modicon Micro-Bus) for connecting I/O expansion cards.Indicator Lights: Power, run, error and communication status indicators for quick on-site diagnosis.Plug-in I/O Slots: Supports up to 8 modules (subject to cabinet layout), realizing various I/O combinations including digital, analog, counting and special functions.
5. Typical Application Fields
Automated Production Lines: Discrete control for packaging, assembly, inspection and other processes.Process Control: Monitoring of continuous or batch processes in chemical, food & beverage and pharmaceutical industries.Building & Facility Management: Centralized control of air conditioning, lighting and access control systems.Small-scale Motion Control: Simple positioning of conveyor belts and robot end effectors.Energy Management: Start-stop control and monitoring of distribution cabinets and frequency converters.
