The 1756-L55 is a processor module in the ControlLogix family, designed and produced by Allen-Bradley/Rockwell Automation. This module is a common component in ControlLogix industrial environments and is known for its high quality and top performance.

The processor module meets different IEC 60068 rating requirements in terms of temperature, humidity, vibration and shock resistance, demonstrating its exceptional durability and reliability. In terms of backplane current, the module has a backplane current of 0.014 amps at 24 volts DC, compared to 1.23 to 1.25 amps at 5.1 volts DC. In addition, it has a power rating of 5.6 to 5.7 watts and a heat dissipation of 19.1 to 19.4 BTU per hour.

In terms of functionality, the 1756-L55 processor module has a basic insulation type and a continuous isolation voltage of 30V, and has been tested to withstand a voltage of 707V DC 60s. In addition, it has specific conductive RF immunity requirements and can operate properly over a certain storage and operating temperature range.

The ControlLogix architecture is a technology platform that integrates multiple control functions, including sequence control, motion control, transmission and process control. Unlike traditional programmable controllers, the ControlLogix system has a modular design that allows users to select the appropriate amount of memory, number of controllers, and network type for their specific application. This flexible structure makes it possible to use multiple controllers, networks and I/O modules in the same rack.

At the same time, the ControlLogix controller also provides an upgradeable solution for addressing a large number of input and output points. Controllers can be inserted into any slot of the ControlLogix input/output rack, and multiple controllers can be inserted into the same rack and communicate with each other through the rack backplane but work independently of each other. In addition, ControlLogix controllers also support a variety of communication protocols, such as RS-232-C (DF1/DH-485 protocol), DeviceNet, DH+, ControlNet, EtherNet/IP, etc., to achieve communication with other computers or other processors.

Overall, the 1756-L55 ControlLogix processor module is a high-performance, reliable and flexible industrial automation component that can meet a wide range of complex control needs.
