The Allen-Bradley 1756-L55M14 is a ControlLogix 5555 controller designed for robust industrial applications, featuring 3.5 MB of data and logic memory with 208 KB of I/O memory, all housed within a 1756 chassis with an open style enclosure. Despite its compact weight of 0.36 kg, the controller excels in communication versatility, supporting protocols such as SynchLink, DH-485, Universal Remote I/O serial, Modbus via ladder routine, ControlNet, DeviceNet, and EtherNet/IP, and it is compatible with redundant systems on the same ControlNet network. The unit operates efficiently with backplane currents of 1.25 A at 5.1V DC and 0.14 A at 24V DC, a power dissipation of 5.7 W, and a remarkable thermal endurance, capable of handling environments ranging from 0 to 60 degrees Celsius in operation, and -40 to 85 degrees Celsius for storage, while maintaining a vibration resistance of 2 g across 10 to 500 Hz frequencies.
