Product Overview

This CPU module functions as the primary processor for Modicon Quantum automation platforms. It executes user programs and manages all data exchange between I/O modules efficiently. The 140CPU11302C delivers reliable processing power for medium-sized control applications. Its compact design fits seamlessly into standard Quantum rack systems. This processor supports both discrete logic and analog control tasks simultaneously.

Technical Specifications

The 140CPU11302C measures 23.5 cm in height, 9.8 cm in width, and 14.5 cm in depth. It weighs approximately 1.0 kg, including the battery and memory cartridge. This module draws 880 mA from the +5 VDC backplane supply. It features one RS232 serial port for programming and diagnostic access. The unit includes 256 KB of internal RAM for user application storage. An additional 256 KB of flash memory retains programs during power interruptions. The processor executes Boolean instructions in 1.0 microsecond for dependable performance. It supports up to 64 digital I/O modules and 16 analog modules per system. A lithium battery maintains real-time clock and memory data for 5 years typical. The module provides LED indicators for power, run, and fault status monitoring.

Processing and Memory Architecture

This CPU executes applications developed in Modsoft or Concept programming software. It supports ladder logic, instruction list, and structured text programming languages. The 140CPU11302C handles both local and remote I/O through the Quantum backplane. Users can store up to 32,000 discrete registers and 8,000 analog registers in data memory. The processor also supports online debugging without interrupting the running program.

Physical and Electrical Parameters

Installation and Configuration Steps

Install the 140CPU11302C into slot 1 of the Modicon Quantum rack for proper addressing. Secure the processor using the retaining screws at the top and bottom positions. Insert the memory cartridge containing the application program into its designated slot. Connect the programming cable to the RS232 port for software access. The CPU automatically loads the program and initiates self-diagnostics upon power-up. Monitor the LED status indicators to confirm normal operation.

Typical Applications

This processor serves water and wastewater treatment facilities, mining operations, and food processing plants. It controls conveyor systems, pumping stations, and mixing equipment effectively. The 140CPU11302C also supports building management and material handling applications. Its reliable performance suits continuous process and batch control environments.
