PLC Memory Modules | Allen-Bradley 1756-M16
The 1756-M16 is a ControlLogix expansion memory module manufactured by Allen-Bradley / Rockwell Automation, providing 7.5 Mbytes of dedicated memory for Logix5555 controllers. It installs directly onto the controller board to expand available capacity for application code, complex control routines, and large data tag structures without using additional chassis slots.
Controller Integration and Performance
Designed specifically as a daughtercard for the Allen-Bradley Logix5555 (1756-L55 series) controller platform, the 1756-M16 mounts internally onto the main processor board. This internal connection provides high-speed, direct access to the expanded 7.5 Mbyte memory space, ensuring fast execution times and full data retention during complex control tasks.
Key features and usage details include:
- Logix5555 Compatibility: Built exclusively for integration with 1756-L55 / Logix5555 processor models.
- Onboard Footprint: Plugs directly into the processor memory expansion slot, keeping standard backplane slots open for I/O and communication modules.
- Backplane Power: Draws 850 mA operating current at 5.1 VDC directly from the host controller assembly.
