Schneider Electric TSXMRPC003MC Modicon Quantum Configurable SRAM Memory Extension

Description

Memory capacity expansion for Modicon Quantum controllers is achieved using the TSXMRPC003MC PCMCIA SRAM memory card. This configurable memory extension module provides reliable volatile storage for application programs, register data, and system configuration files within the host processor. By expanding the available memory footprint, it allows industrial automation systems to execute larger, more complex control logic programs and manage extensive data logging requirements directly at the controller level.

The card utilizes high-speed Static RAM (SRAM) technology, ensuring rapid read and write access times compatible with the demanding execution cycles of Modicon Quantum CPUs. It features a configurable architecture, allowing system engineers to partition the memory space between application code and data storage to optimize processor performance. An integrated backup battery safeguards stored data against power interruptions, maintaining memory integrity even when the card is removed from the processor slot.

Features

• Configurable memory allocation ranging from 192 KB to 3072 KB for application programs, and 2880 KB to 0 KB for data storage.
• Standard PCMCIA Type I form factor for direct integration into compatible Modicon Quantum processor slots.
• High-speed SRAM technology ensures zero-wait-state execution and unlimited write endurance.
• Built-in auxiliary battery backup to prevent data loss during system power-down or card transit.
• Write-protection switch to secure stored control programs from unauthorized or accidental modification.

Applications

• Modicon Quantum PLC system memory expansion for complex industrial processes.
• Data logging, historical trend storage, and recipe management in manufacturing environments.
• Program backup and system restoration in power generation, water treatment, and chemical processing plants.

Installation Guidelines

Before installing or removing the memory card, ensure that the Modicon Quantum processor is powered down or follow the specific hot-swap procedures outlined in the CPU hardware manual. Align the TSXMRPC003MC card with the PCMCIA slot guide rails on the processor module and slide it firmly into place until the eject button engages. Avoid touching the connector pins to prevent electrostatic discharge (ESD) damage. Regularly inspect and replace the auxiliary backup battery according to the manufacturer's maintenance schedule to guarantee continuous data retention during power outages.
