The Allen-Bradley 1756-L55M13 ControlLogix 5555 Series A controller is a sophisticated module featuring a robust 1.5 Mbytes of data and logic memory alongside 208 kbytes of I/O memory, although it lacks nonvolatile memory. It supports multiple communication options, including DeviceNet, ControlNet, and Ethernet/IP, making it highly versatile for different network configurations. With an operating temperature range of 0 to 60 degrees Celsius and a high resistance to shock and vibration, this open-style controller is durable yet lightweight at 12.5 oz. Its backplane currents measure at 0.014A at 24V DC and 1.23A at 5.1V DC, with a power dissipation of 5.6W and thermal dissipation of 19.1 BTU/hr. It utilizes a basic insulation type with a continuous isolation voltage of 30V and features replaceable batteries, specifically compatible with the 1756-BA1, ensuring long-term reliable operation within redundant systems on the same ControlNet network.
