The programmable automaton CJ2M is one of the most complete models within the family of Omron PLCs. This has arisen as a consequence of the entire trajectory that the brand has followed in the development and manufacture of control systems, together with its great appetite for innovating more and more.

Produced as an evolution of the CJ1 controller, it has very similar characteristics but with the necessary improvements to stay in the top positions in the market against its closest competitors. As a result, the device has the most innovative technology but with the ability to be expanded by the expansion systems compatible with its predecessor, the CJ1 system. Thanks to this, anyone who seeks to update their equipment, will only need to change the main system, thus being able to maintain the expansions that are available, assuming that they will work correctly.

In addition, among its best features can be noted the rapid start-up of the device thanks to the use of standard USB or Ethernet ports. As a consequence, they make the access to programming instantaneous. Along with this, it should be noted that all the improvements incorporated to this device have been added in order to increase the speed of production and improve the programming conditions so that the operator in charge of handling it does not find any type of obstacle.


Available in different versions depending on the needs required for its use.
