Overview

The 140CPU11303C is a Processor in the Modicon Quantum automation platform range from Schneider Electric. It is engineered for industrial automation duties within the Modicon Quantum ecosystem.

Application & Technical Notes

As a processor, the 140CPU11303C is intended for deployment in panel-based control cabinets and machine enclosures where Modicon Quantum equipment is installed. It hosts the application program, executes the control cycle and orchestrates I/O scanning, communication and diagnostics for the station.

Key published characteristics include an operating temperature range of 32…140 °F (0…60 °C). These values should be confirmed against the current manufacturer datasheet before final selection, as options and suffixes vary by configuration.

Maintenance & Diagnostics

Respect the published operating temperature window (32…140 °F (0…60 °C)); do not exceed it during commissioning or in enclosed panels without airflow. For storage and transit, keep the unit within -40…185 °F (-40…85 °C). Avoid condensation — the rated humidity is 95 % without condensation; store and operate the module in a dry, pollution-degree-appropriate enclosure. Back up the application program and parameter set before any firmware or hardware change; verify the memory/real-time-clock battery where fitted and replace on schedule. Monitor the module health LED and controller diagnostics; plan spares for critical stations to minimise downtime. Always de-energise the circuit and follow lock-out/tag-out before handling; refer to the official instruction bulletin for service procedures.

Sourcing & Procurement

When sourcing the 140CPU11303C, distinguish three supply tiers: (1) genuine Schneider Electric stock from an authorised distributor; (2) compatible equivalents or surplus/NOS (new-old-stock) from third parties; (3) alternative parts offering equivalent function. Genuine supply carries the full warranty and traceability; compatible or alternative items may be cheaper but should be validated for form, fit, firmware and certification before use in a live system. PLCXpert publishes this page as an independent reference and does not sell the part — verify every claim with the manufacturer or your distributor.

Confirm the CPU matches your Modicon Quantum architecture, memory size, firmware revision and any required option/communication modules. Lead times and pricing vary by region and lifecycle status; obtain a current quote from an authorised channel rather than relying on stale listings.

Specifications

The 140CPU11303C is a processor module from Schneider Electric's Modicon Quantum series, featuring a robust 80186 microprocessor. It operates at a clock frequency of 20 MHz and includes 368 KB of internal RAM, ensuring sufficient memory for processing tasks.

Description

NoteThe 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.
