Omron CJ1: Quick and easy setup
The connection of the Omron CJ1 PLC modules is done simply by joining them together without any rack. There is nothing easier to create ad hoc configurations, and the installation of the PLC in electrical panels will no longer have to take into account bulky racks.
Built-in smart functions
The heart of the machine control system is the CPU. The CPUs of the Omron CJ1 are available in various models, from cheap ones for simple sequence control, to those ultra-powerful high-speed capable of handling up to 2560 I / O points. However, the main advantage is the opportunity of installing any module on any type of CPU, with a consequent reduction in inventory.
Transparent communications
The built-in automatic bridge functions ensure transparent communications even between networks of different levels and types. Programming and data transfer operations are performed in complete transparency both on open networks, such as Ethernet, Profibus-DP and DeviceNet, and on Omron’s cost-effective proprietary networks. The open communication modules of Omron CJ1 also allow you to communicate with any third party device.
Control unit
The special units for speed, position and temperature control can manage part of the operations normally assigned to the CPU, allowing for simpler programming, a higher level of integration and a reduction in wiring. The transparent communications of Omron CJ1 ensure complete distributed control of machines, configurable from any access point to the existing network.
Analog and digital I/O moduls
The I/O modules of Omron CJ1, from entry-level to ultra-compact high-density models, can be installed on any CPU, allowing functions to be distributed exactly where they are needed.
Omron CJ1 – The best size / performance ratio
With the Omron CJ1 PLC it is possible to combine CPUs of different power, integrate modules with special functions and use a wide range of I/O modules to satisfy every possible automation need. Thanks to the ultra-compact profile, the Omron CJ1 PLC series offers the best size / performance ratio in the industry. Furthermore, since it does not require a rack, the required installation space never exceeds that actually occupied by the installed modules.
