PRODUCT INFORMATION
Product Overview
The Schneider Electric 140CPU43412A is a Modicon Quantum processor module designed for industrial control architectures. It features an integrated 486 controller operating at a clock frequency of 66 MHz. A built-in mathematical coprocessor accelerates floating-point calculations and complex arithmetic operations. This unit provides 896 KB of internal RAM to store user logic and control system data.
Communication is supported through one Modbus Plus port and two Modbus RS-232 serial interfaces. The module draws a bus current requirement of 500 mA from the backplane. Total power consumption is rated at 4.5 W under standard operating conditions. Operating temperature limits range from 0°C to 60°C in industrial backplane environments.
