Allen-Bradley 1764-MM1RTC RTC Memory Module MicroLogix 1500

The Allen-Bradley 1764-MM1RTC MicroLogix 1500 Memory Module with Real-Time Clock is an 8 KB memory expansion designed for MicroLogix 1500 controllers, combining RAM storage with an integrated real-time clock. It plugs into the MicroLogix 1500 backplane to extend program and data memory while providing timekeeping relevant to timestamping events and coordinating time-based control in your logic. Key specifications include 8 KB of memory, a built-in RTC, and an IP20 enclosure suitable for standard industrial cabinet installations. If the module is installed while the controller is executing, it may not be recognized until a power cycle or a non-executing state (program mode or fault condition) is entered. This memory module with RTC is intended for applications that require both memory expansion and clock functionality, such as data logging with timestamps, event timing, and simple time-based sequencing within MicroLogix 1500 projects.
