Allen-Bradley 1772-MEB RAM Memory Module
The Allen-Bradley 1772-MEB is a CMOS RAM Memory Module designed to enhance the memory capacity of PLC-2/20 and PLC-2/30 programmable controllers. This module provides a flexible and expandable solution for industrial automation systems requiring increased data storage.
Key Features
- Expandable Memory Capacity: Equipped with four sockets labeled A to D, the 1772-MEB allows for the addition of compatible memory segments, such as the 1772-MR, 1772-MT, 1772-MS, and 1772-MS8. This configuration enables expansion up to 8192 additional words of memory, accommodating complex applications and extensive data processing needs.
- Seamless Integration: Designed for easy installation into the rightmost slot of the PLC-2 processor chassis, the module ensures a secure and efficient connection. All added memory segments must be installed contiguously, with keyed connectors facilitating precise alignment and preventing improper installation.
- Data Integrity: As a volatile memory device, the 1772-MEB requires an external backup battery to preserve data during power interruptions, ensuring continuous operation and data retention.
- Electrostatic Discharge (ESD) Sensitivity: The module is sensitive to ESD, necessitating proper handling and adherence to safety protocols during installation and maintenance to prevent potential damage.
