Schneider 140CPU11303C Quantum Processor Module

140CPU11303C Processor Module for Modicon Quantum Control Systems

Product Introduction

The 140CPU11303C from Schneider Electric serves as the central processing unit for Modicon Quantum automation platforms. This module incorporates an 80186 microprocessor operating at 20 MHz, delivering reliable performance for medium-scale control applications. Its 368 KB of internal RAM provides sufficient memory for program execution and data handling. Additionally, the 140CPU11303C supports both local and remote I/O configurations, making it adaptable to various system architectures. The built-in watchdog timer enhances system reliability by monitoring execution integrity. For long-term maintenance, the unit includes a lithium battery with a 10-year life expectancy, reducing frequent replacement needs.

Processor and Memory Architecture

The 140CPU11303C utilizes the proven 80186 processor architecture, known for its efficiency in industrial environments. The 20 MHz clock frequency ensures responsive execution of control logic. Program execution time ranges from 0.3 to 1.4 ms per 1,000 LL984 instructions, balancing speed with deterministic behavior. Furthermore, the 368 KB internal RAM accommodates both application code and data tables without external memory expansion.

The module does not include a mathematical coprocessor, making it suitable for logic-intensive rather than calculation-heavy applications. However, it handles standard arithmetic and comparison operations effectively. The watchdog timer is set to 250 ms, resetting the processor if program execution stalls.

I/O Capacity and Network Support

The 140CPU11303C offers flexible I/O configurations to match system requirements. It supports 64 I/64 O for both local and remote I/O. For distributed networks, it handles 30 I/32 O per network. Additionally, the module manages 500 I/500 O across distributed networks, providing substantial capacity for medium-sized installations.

This processor supports up to 31 remote drops and 63 drops per distributed network. It accommodates 2 remote networks and 3 distributed networks simultaneously. Such connectivity enables the 140CPU11303C to coordinate multiple field devices and sub-systems effectively.

Communication Ports and Protocol Support

The 140CPU11303C includes two built-in communication ports for flexible connectivity. One port supports Modbus Plus, a high-speed token-passing network ideal for peer-to-peer and master-slave communications. The second port provides Modbus RS232, enabling direct connection to programming terminals, HMIs, or other serial devices.

Moreover, the processor supports up to 2 communication modules, including NOM, NOE, CR, and NMS types. This expandability allows integration with Ethernet, additional serial networks, or remote I/O adapters. The 140CPU11303C is compatible with Concept and ProWORX 32 software for programming and configuration.

Power Consumption and Battery Specifications

The 140CPU11303C draws 790 mA from the backplane bus, which is within typical Quantum rack capacity. The lithium battery provides 1.2 Ah capacity, operating at 7 µA typical and 210 µA maximum draw. Consequently, the battery life extends to approximately 10 years under normal conditions. This long service interval minimizes maintenance overhead in continuous operations.

Environmental and Mechanical Parameters

The 140CPU11303C operates within 0°C to 60°C ambient temperatures, suitable for most industrial control rooms. Storage temperatures range from -40°C to 85°C. Relative humidity tolerance reaches 95% without condensation, protecting against moisture-related failures.

A conformal coating (Humiseal 1A33) guards against dust, humidity, and chemical exposure. The module carries cUL, FM Class 1 Division 2, UL 508, and CSA C22.2 No 142 certifications. These approvals confirm its suitability for hazardous and non-hazardous locations. Electrostatic discharge immunity meets 4 kV contact and 8 kV air discharge per IEC 801-2. The unit weighs only 0.3 kg, facilitating easy installation.

Installation and Configuration Guidance

Installing the 140CPU11303C follows standard Quantum rack procedures. First, power down the rack before inserting the module. Align the processor with the designated slot, typically the first slot on the left. Push firmly until the retaining clips engage securely.

Next, connect the programming terminal to the RS232 port for initial configuration. Use Concept or ProWORX 32 software to download the application program. Configure the Modbus Plus network parameters, including node addresses and baud rates. Additionally, set up remote drops and distributed I/O mappings as per system design. Finally, verify operation through the diagnostic LEDs.
