Schneider TSX17-ACC1 Backup Power Module Specs
Core Technical Specifications & Parameters
The TSX17-ACC1 functions as a dedicated backup power module for Schneider Electric TSX Micro PLC systems. This unit delivers a nominal output voltage of `3.6 volts DC` to maintain essential memory retention. Its energy storage capacity is rated at `1200 milliamp-hours (mAh)`, providing reliable support for low-current applications. The module utilizes a lithium-based primary cell chemistry that is strictly non-rechargeable for safety compliance. It sustains a maximum continuous discharge current of `100 milliamperes (0.1 A)` for consistent PLC backup operations. The operating temperature range spans from `-40 degrees Celsius to +85 degrees Celsius`, ensuring functionality in harsh industrial environments. Storage capabilities extend further from `-60 degrees Celsius to +85 degrees Celsius` for logistical flexibility. This unit features a remarkably flat voltage curve advantageous for stable low-current PLC backup duties. It adheres to stringent safety certifications including IEC 60086 and UL 1642 standards.

Professional Installation & Wiring Guidelines
Adhere to strict electrostatic discharge precautions when handling this backup power module during installation. Ensure the host TSX Micro PLC system is completely powered down before inserting the TSX17-ACC1 into its designated slot. Verify the module is firmly seated into the connector to establish a secure electrical connection. Do not attempt to recharge this module as its lithium chemistry is non-rechargeable and poses a safety hazard. Confirm that the ambient temperature remains within the specified operating range before deploying the system. Replace the module only after its voltage has dropped below the critical threshold for data retention. Employ appropriate personal protective equipment when working with lithium-based components in confined spaces. Test the backup operation by momentarily disconnecting main power to verify data preservation.

Frequently Asked Questions (FAQ)
Q: What is the precise function of the TSX17-ACC1 module in a PLC system?
A: It provides backup power to retain volatile memory contents when the main PLC power supply is interrupted completely.
Q: Can this module be used in applications with extreme cold environments below freezing?
A: Yes, its approved operating range extends down to minus 40 degrees Celsius for reliable performance.
Q: What happens if the module is subjected to a current draw exceeding its discharge limit?
A: Exceeding the 100 milliampere continuous rating may permanently damage the cell and void its certification.
Q: How often should this backup module typically be replaced in a standard installation?
A: Replacement is recommended based on the 10-year shelf life under normal 20 degree Celsius storage conditions.
Q: Is this module compatible with other PLC brands besides the TSX Micro series?
A: This unit is engineered specifically for the Schneider Electric TSX Micro PLC connector footprint and voltage requirements.
