Schneider TSX17-ACC1 Backup Power Module for TSX Micro PLCs

Technical Specifications Breakdown

Key parameters for the TSX17-ACC1 are listed below for quick reference:

Industry Applications

1. Manufacturing Line PLC Backup

In automotive assembly lines, TSX Micro PLCs control conveyor sequences and robotic interfaces. The TSX17-ACC1 ensures that during a brief power sag, the PLC retains its program state and position data, avoiding re-homing sequences that can delay production by hours.

2. Remote Monitoring Stations

The flat voltage curve guarantees consistent backup power over the module's life.

3. Critical Safety System Memory Hold

In safety-instrumented systems using TSX Micro PLCs, the backup module preserves diagnostic logs and fault records during power loss. This aids in post-incident analysis without data corruption.

Installation & Setup Guidance

When installing the TSX17-ACC1, ensure the main PLC power is disconnected. Locate the dedicated backup battery connector on the TSX Micro CPU module (refer to your PLC manual for exact position). Insert the module firmly until it clicks into place. Verify polarity markings match. After installation, power up the PLC and check the battery status LED (if available) or diagnostic register to confirm proper connection. Do not attempt to recharge this non-rechargeable lithium cell.

Maintenance & Reliability

Given the module's lithium primary cell chemistry, no routine maintenance is required. However, inspect the module annually for physical damage or corrosion on contacts. The shelf life of up to 10 years at 20°C means spares can be stored long-term. Replace the module immediately if the PLC indicates low battery voltage or if the module has been in service beyond its expected life (typically 5-7 years depending on discharge cycles). Always store spare modules in a cool, dry environment within the -60°C to +85°C storage range.

Critical PLC Memory Retention: The TSX17-ACC1 Solution

In industrial automation, unexpected power loss can corrupt PLC program memory or lose critical process data. The Schneider Electric TSX17-ACC1 backup power module addresses this challenge directly. Designed for the TSX Micro PLCs series, this module provides a dedicated 3.6 volts DC output to maintain volatile memory and real-time clock functions during main power interruptions. Its 1200 mAh energy storage capacity ensures extended retention periods for low-current applications, preventing costly downtime and data recovery efforts.

Compatibility & Integration

The TSX17-ACC1 is specifically designed for the Schneider Electric TSX Micro PLCs series. It integrates directly into the CPU module without additional wiring. The module is compliant with IEC 60086 and UL 1642 safety standards, ensuring reliable operation in industrial environments. For compatibility with other PLC families, consult AutoDCSTech for cross-reference options.

Selection Guide & Purchasing Advice

When selecting a backup power module for your TSX Micro PLC, verify that your application's continuous discharge current does not exceed 100 milliamperes. For higher current needs, consider an external UPS. The TSX17-ACC1 is a genuine Schneider Electric part, available at AutoDCSTech. We stock this module and can advise on lifecycle status.
