Allen Bradley 1756-CP3

The Allen Bradley 1756-CP3 is installed in the ControlLogix rack. Once inserted, it can add multiple independent communication channels specifically for communicating with external computers and displays, thereby freeing up the main CPU to focus on control logic operations. As one of the Chinese suppliers, Tongtu not only offers high-quality products but also ensures worry-free after-sales service.

Application scenario

The application scenario of this Allen Bradley 1756-CP3 is quite clear. The most common case is those assembly lines where the operation consoles are located far away from the cabinets. For instance, in automotive assembly lines or large packaging lines, there are several operator stations. If a cable is pulled from each station to the network port of the CPU, there would be too many cables and it would be difficult to manage. At this point, adding a CP3 would be beneficial as it can gather all the cables from the operation stations to this one, making the wiring much neater. In the packaging workshops of the food and beverage industry, there are many touch screens that need to be connected to the network. Using it can easily expand enough access points. Additionally, for some outdated systems, the original CPU network ports are broken or insufficient. Adding a CP3 is also the most cost-effective solution for upgrading.

Certification

Alan Bradley 1756-CP3 is a high-performance communication coprocessor module specifically designed for the Logix5000 control system. The CE certification mark and UL/cUL certifications we have obtained ensure electrical insulation. The overall electrical design and strict energy release standards that comply with ATEX and IECEx explosion-proof regulations enable this module to guarantee that it will not become an ignition source in hazardous gas environments. These multiple authoritative certifications collectively ensure the stable and safe operation of this module in various demanding industrial scenarios worldwide.

Customer review

For many years, Tongtu has been selling Allen Bradley 1756-CP3. It has received high praise from many customers and they have come to trust our original products. When dealing with hundreds or thousands of Axis (axis) servo controls, or when mounting thousands of EtherNet/IP devices, the task load of a regular ControlLogix CPU will instantly exceed its capacity. By taking over the parsing and routing distribution of the underlying messages, the utilization rate of the main CPU can often drop from over 80% to around 20%, allowing the controller to focus on stable core logic calculations.
