Description
The Schneider Electric 140CPU42402C is a central processing unit designed for the Modicon Quantum automation platform. Powered by a 32-bit microprocessor running at 66 MHz, this module delivers high-speed control logic execution and manages local and remote I/O subsystems for medium- to large-scale industrial applications.
Processing Performance and Memory Configuration
Featuring an execution speed of 0.25 µs per boolean instruction, the processor ensures fast, deterministic handling of logic routines and time-sensitive tasks. The memory architecture includes 256 KB of battery-backed program RAM (supporting up to 128 KB for user application code) alongside 256 KB of data memory. An internal 1200 mAh lithium battery preserves retentive program states during system power outages.
Scalability and Communication Capability
The module controls up to 2048 digital I/O channels and 512 analog I/O channels distributed across up to 16 local and remote racks. Onboard communication options include a Modbus RS-232 serial port and a mini-B USB interface for programming and commissioning. Front-panel LED indicators (PWR, RUN, ERR, COM) provide real-time status diagnostics for immediate visual verification during operation.
