As the flagship redundant controller of Schneider Quantum series, AEG Modicon 140CRA21210 adopts a dual machine hot standby architecture as its core, becoming the preferred control core for key processes in high-risk industries such as power and petrochemical, ensuring uninterrupted production operation.

In terms of core performance, it is equipped with a 32-bit processor, with a computing speed of 0.1 μ s/Boolean instruction, supporting 4MB program memory and 8MB data memory, meeting complex control requirements. The dual machine hot standby design achieves<3ms millisecond level switching through a dedicated bus, seamlessly taking over master-slave faults and avoiding production interruption losses.

Outstanding compatibility and scalability: compatible with Quantum's full range of I/O modules, supporting 16 local racks and 32 remote rack extensions, with a maximum of 8192 I/O points; Built in 2 Ethernet ports, 1 Modbus Plus port, and RS-485 port, compatible with mainstream protocols such as Profinet, seamlessly integrating with SCADA, DCS, and third-party devices.

Strong adaptability to industrial environment: 24V DC wide voltage power supply (19.2V-31.2V), working temperature of 0 ℃ -60 ℃, tolerance to 10% -95% non condensing humidity, anti electromagnetic interference in accordance with EN standards, built-in overvoltage and overcurrent protection and EEPROM non-volatile storage, data loss during power failure.

Convenient programming and operation: Supports international standard programming methods such as ladder diagrams and FBD, compatible with Unity Pro software; Built in diagnostic function, intuitive display of faults, support for remote maintenance, and reduce debugging and operation costs.

Widely used in key fields such as generator control, crude oil refining, steelmaking and continuous casting, rail transit signaling, water treatment core processes, etc., providing safe and reliable automation solutions, and enjoying Schneider's 24 month official warranty.
