PRODUCT INFORMATION
Product Overview
The Schneider Electric 140CPU21304 is a Modicon Quantum processor module designed for industrial automation applications. It integrates a dedicated math processor operating at a 20 MHz clock frequency. This computational speed allows precise execution of control tasks and system calculations. The module provides 768 kB of internal memory capacity for program execution and data storage. Communication across automation networks is handled via an integrated Modbus Plus network interface.
The 140CPU21304 operates using a standard 24 VDC input voltage. It draws a maximum power consumption of 250 mA during normal controller operation. The internal backplane bus current requirement is rated at 200 mA. Operating temperature ratings span from 0°C to 60°C for varied factory environments. Storage temperature ratings range between -40°C and 85°C. The module weighs 2.00 lbs, corresponding to approximately 0.91 kg.
