Product Overview

The Schneider TSXMRPP224K SRAM memory extension provides 224 kilobytes of additional application storage for Premium automation controllers. This high-speed memory module enhances program execution and data handling capabilities. It plugs directly into the dedicated memory slot on the TSX Premium processor. System integrators use this extension for complex machine control sequences and data-intensive applications.

Memory Architecture and Access Speed

This extension card offers 224 kilobytes of static RAM with battery backup protection. The memory operates with a 70-nanosecond access time for rapid read and write operations. It organizes data into 16-bit words for efficient processor communication. The module employs CMOS technology for low power consumption during active use. This architecture maintains deterministic scan cycle performance.

Data Retention and Backup Systems

A factory-installed lithium battery sustains memory content for up to three years. The battery automatically activates when the main power supply drops. A green LED indicator confirms valid battery status and data integrity. The module includes a supercapacitor for temporary backup during battery changes. This redundant system prevents data loss during maintenance procedures.

Compatibility with Premium Processors

The Schneider TSXMRPP224K works exclusively with TSX P57 series CPUs. It supports all TSX Premium 57 processors including 57-104, 57-204, and 57-304 models. The processor automatically detects and configures the memory upon startup. Existing application programs require no modification for compatibility. This plug-and-play integration simplifies field upgrades significantly.

Program Storage and Data Logging Capacity

This memory extension stores up to 12,000 network nodes of ladder logic. It accommodates 1,500 function blocks for structured text programming. The module also reserves space for 10,000 internal data registers. Users can log process trends for up to 30 days with one-second intervals. This capacity suits medium to large-scale automation applications.

Physical Dimensions and Installation

The memory card measures 65 millimeters in length and 35 millimeters in width. Its height totals 15 millimeters including the connector pins. The unit weighs approximately 0.08 kilograms for lightweight handling. It inserts into the processor’s front-facing memory slot firmly. A spring-loaded ejector lever simplifies removal when necessary.

Electrical Characteristics and Power Draw

The Schneider TSXMRPP224K consumes 50 milliamperes from the 5 V DC supply. It draws negligible current during the standby mode. Total power dissipation measures 0.25 watts under typical operation. The module generates virtually no heat inside the processor enclosure. This efficiency supports high-density rack configurations without cooling issues.

LED Status Indicators and Diagnostics

A single bicolor LED displays the module’s operational status clearly. Green indicates normal operation with valid data retention. Amber signals a low battery condition requiring replacement. The CPU reads the module’s diagnostic register through the backplane. This status monitoring prevents unexpected data loss events.

Environmental Specifications and Durability

The unit operates from 0°C to 60°C ambient temperature. It withstands 5% to 95% non-condensing humidity levels. The module meets IEC 61131-2 standards for industrial control equipment. Its solid-state construction eliminates moving parts for long-term reliability. The PCB includes conformal coating for moisture and dust protection.
