The Allen-Bradley 1756-M16 is designed exclusively for ControlLogix5555 controllers, offering 7.5 MB of non-volatile memory. It is essential to ensure compatibility with the existing system before replacement, as this module is only compatible with specific controllers such as the 1756-L55M series. Operating efficiently within a temperature range of 0 to 60 degrees Celsius, the 1756-M16 is CSA, C-Tick, CE, and UR certified, making it a reliable choice for enhancing system capabilities, as only one memory board can be installed in a controller at a time.
