Memory Capacity and Data Retention
The Schneider TSXMC70E48 provides 256 KB of user program storage. This capacity handles approximately 15000 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 16 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 TSXMC70E48 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 12 mA from the CPU during normal use.
