140CPU11303C

The processor module 140CPU11303C from the Modicon Quantum series by Schneider Electric utilizes an 80186 processor architecture, characterized by its efficient 20 MHz clock speed. This module is equipped with 368 KB of RAM to facilitate operational tasks across various industrial environments.

To ensure system reliability, the built-in watchdog timer is set to 250 milliseconds, providing essential monitoring for system stability. Timekeeping accuracy is maintained with a clock drift rating of ±8 seconds per day when operating within a temperature range of 0 to 60 degrees Celsius.

This module supports a variety of I/O configurations, allowing for up to 64 input and output words on both remote and local systems, with an added capacity for 30 I/O words distributed across the network. The 140CPU11303C can manage 500 input and output words in a distributed setting, providing flexibility for extensive automation systems.

The architecture integrates up to 31 remote drops across three distributed and two remote networks, facilitating robust connectivity. A lithium battery is included, with a capacity of 1.2 Ah, designed to operate at a minimal current of 7 µA and a maximum of 210 µA. The battery life expectancy is around 10 years, ensuring long-term operation without frequent maintenance.

Communication options are enhanced with one Modbus Plus and one RS232 port, contributing to its compatibility within existing networks. The communication module processor supports various configurations, including two NOM, NOE, CR, and NMS communications, further augmenting the system's versatility for diverse application requirements.
