Product Introduction
The Allen Bradley 1785-ME16 EEPROM Backup Memory Cartridge is a non-volatile memory module designed for the PLC-5 series programmable logic controllers. It provides a reliable method for storing and preserving control programs, configuration data, and system parameters when power is removed from the controller.
With a 16 K word EEPROM storage capacity, the module allows users to back up the processor memory and automatically restore the control program during system startup. This function is particularly important in industrial environments where system recovery and fast restart are critical for maintaining continuous production.
The 1785-ME16 memory cartridge installs directly into compatible PLC-5 processors and operates within standard industrial temperature and humidity ranges. Its rugged design ensures stable performance even in environments subject to vibration or electrical disturbances, making it a dependable solution for protecting PLC program data in automation systems.
