Functional Overview

The Schneider TSXMRPC001M memory extension module expands the data storage capacity of Premium and Micro PLC systems. This compact accessory provides additional space for complex application programs and data logging. It attaches directly to the processor via the dedicated extension port. Control engineers can store larger ladder logic and structured text programs without performance degradation.

Storage Capacity and Memory Architecture

This module offers 128 kilobytes of battery-backed static RAM for user data. It includes an additional 64 kilobytes of flash EEPROM for firmware and configuration backup. The memory operates with an access time of 70 nanoseconds for fast read-write cycles. A supercapacitor provides temporary power during battery replacement procedures. This dual-storage design ensures data safety against unexpected power interruptions.

Compatibility and System Integration

The Schneider TSXMRPC001M works exclusively with TSX Premium 57 and TSX Micro 37 series controllers. It occupies one slot in the rack-based expansion bus architecture. The module automatically configures itself after the CPU detects its presence. Existing application programs require no modification to utilize the extra memory. This seamless integration saves engineering time during system upgrades.

Data Retention and Backup Mechanisms

A field-replaceable lithium battery maintains data integrity for up to one year. The battery holder incorporates a polarity reversal protection feature. A green LED indicator confirms active battery status at all times. The supercapacitor sustains memory content during battery swaps. This redundancy prevents data loss during routine maintenance operations.

Physical Dimensions and Mounting Specifications

The module measures 100 millimeters in width and 54 millimeters in height. Its depth totals 87 millimeters including the front face. The unit weighs approximately 0.32 kilograms for easy handling. It snaps onto a DIN rail or mounts with standard M4 screws. The front panel includes a removable protective cover for the battery compartment.

Electrical Characteristics and Power Draw

The Schneider TSXMRPC001M consumes 120 milliamperes from the 5 V DC bus. It requires no separate external power supply for operation. Total power dissipation reaches 0.6 watts under typical conditions. The module generates minimal heat inside the control cabinet. Its CMOS technology contributes to low standby current consumption.

Diagnostic Indicators and Status Reporting

Two front-mounted LEDs display operational status and fault conditions. A green READY light signals normal operation and successful initialization. A red ERROR light blinks when the module detects memory corruption. The CPU receives status updates through the backplane communication protocol. Operators can monitor these indicators during system startup sequences.

Environmental Ratings and Operating Limits

The unit operates reliably from 0°C to 55°C ambient temperature. It tolerates relative humidity between 5% and 95% without condensation. The module meets EN 61131-2 requirements for industrial control equipment. Its enclosure offers IP20 protection against accidental contact. The design excludes any user-serviceable parts other than the battery.
