It combines a secure digital (SD) memory card for program and data backup with an integrated real-time clock for time-based operations. The module enables automatic program transfer, data logging, and firmware updates directly from the SD card, reducing downtime during maintenance or replacement. The RTC supports time stamping of events and alarms, essential for sequencing, logging, and audit-trail applications. Installation is simple via the Micro820 plug-in slot, and the module is automatically detected and configured by the controller. Key Features: Design: Memory and real-time clock plug-in module for Micro820 PLCs. Memory Function: Provides program and data backup via SD card. RTC Function: Integrated real-time clock enables time/date stamping. Automation Support: Allows automatic program download and firmware updates. Integration: Seamlessly detected and configured by Micro820 controllers. Installation: Compact plug-in design for quick installation and replacement. Reliability: Non-volatile storage ensures data retention during power loss. Application Range: Suitable for small machine control, HVAC, and remote monitoring. The 2080-SDMEMRTC-SC delivers the backup, scheduling, and data integrity capabilities required to enhance the performance of Micro820-based automation systems.
