Choose from I/O that is distributed around the application or integrated with the controller. Allen-Bradley offers the greatest advantage with the power of the NetLinx architecture.
The ControlLogix, CompactLogix, PLC-5, SLC 500, and MicroLogix programmable controllers all offer I/O that can be installed locally in the same chassis as the processor.
Additionally, through the use of I/O communication networks, I/O for these platforms can also be distributed in locations remote from the processor, closer to the sensors and actuators, reducing wiring costs. Having the freedom to monitor and control I/O across an I/O link means you can select I/O products from a variety of platforms, which include a variety of integrated termination solutions.
Rockwell Automation offers a wide selection of more granular distributed, In-Cabinet IP20 I/O for use in your control system. These range from simple 2-I/O blocks to 128-I/O blocks, to modular I/O that offers increased flexibility for your exact needs, to the intrinsically safe FLEX Ex I/O modules, plus the addition of hardened IP67 block and modular I/O products for mounting On-Machine™. All of these choices allow you to tailor your I/O to your precise needs, reducing overall system cost.
In addition, take advantage of our DeviceLogix™ Smart Component Technology that integrates low-cost logic solving capability into your I/O. DeviceLogix-enabled I/O can perform simple control functions locally without the performance constraints typically imposed by a centralized controller and a communication network.
It is available in the 1791D CompactBlock I/O, 1792D ArmorBlock MaXum I/O, and 1799 Embedded I/O product lines. This high performance, low-cost distributed control technology can also be found in Allen-Bradley motor starters, push buttons, and other control components
