Schneider TSXMRPC002M Memory Extension for Modicon Premium PLCs

The Schneider TSXMRPC002M expands the program storage capacity of Modicon Premium PLCs. You can plug this module directly into the dedicated memory slot on the CPU. It retains user logic and configuration data without external power. This solution suits critical automation tasks requiring long-term data persistence.

Technical Specifications and Internal Design

The Schneider TSXMRPC002M measures 85 mm in height. Its width reaches 45 mm, and the depth equals 32 mm. The Schneider TSXMRPC002M weighs approximately 0.08 kilograms. A single small PCB holds all memory and power management circuits. The module stores data using static RAM technology. It includes one replaceable lithium battery for energy storage. This battery preserves contents during controller power-off periods. One 60-pin edge connector interfaces with the Premium CPU.

Memory Capacity and Data Retention

The Schneider TSXMRPC002M provides 128 KB of user program storage. This capacity handles approximately 8000 ladder logic instructions comfortably. The lithium battery offers three years of typical service life. A software flag signals low battery voltage one month in advance. Consequently, you can schedule maintenance without unexpected data loss. The module also retains 8 KB of retentive flag memory. Operating temperature ranges from 0°C to 60°C reliably.

Installation and Data Protection Features

You must insert the Schneider TSXMRPC002M firmly into the Premium CPU memory slot. Transitioning to battery replacement, remove the module from the CPU first. The module includes a write-protect switch for program security. This switch prevents accidental program overwrites during normal operation. For maximum safety, always create a backup before changing the battery. The module consumes only 10 mA from the CPU during normal use.
