SCHNEIDER 140CPU31110
Product Description
The 140CPU31110 is a high – performance CPU module designed for industrial control applications in the Modicon Quantum range4. It is based on the 80486 processor with a math coprocessor, which enables it to handle complex calculations efficiently6. This module is supported by the Unity programming environment, making it suitable for systems that require high performance and reliability in automation and process control6. It serves as a bus master, controlling the local, remote, and distributed I/O of the Quantum system4. The module has two three – position slide switches. The left switch is used to protect the memory, and the right switch is used to select the communication parameters of the Modbus ports4. Additionally, it features a battery – backed real – time clock (RTC) for accurate time – keeping and a watchdog timer to ensure system stability6.
