Connecting with Confidence™ with Allen-Bradley® Distributed I/O
|
Rockwell Automation is the only company that offers the experience with world-class I/O products for virtually every need. Choose from I/O that is distributed around the application or integrated with the controller. Allen-Bradley I/O offers the greatest advantage with the power of the NetLinx™ Open Networks.
Whether you choose a ControlLogix® or CompactLogix® programmable automation controller, a PLC-5®, SLC™ 500, or MicroLogix™ programmable logic controller, or the GuardLogix™ safety programmable controller, each offers I/O that you can install locally in the same chassis as the processor. Through the use of I/O communication networks, you can also distribute I/O in locations remote from the processor, closer to the sensors and actuators, reducing your 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 that include a variety of integrated termination solutions.
Rockwell Automation also offers a wide selection of more granular distributed, In-Cabinet™ (IP20) I/O for use in your control system. These range from simple 4 I/O blocks up to 128 I/O blocks, to modular I/O that offers increased flexibility for your exact needs, or intrinsic safety. For mounting On-Machine™, we offer a line of hardened (IP67/69K) block or module I/O to reduce your wiring and system costs.
In addition, you can take advantage of our DeviceLogix™ Smart Component Technology that integrates low cost logic solving capability in your I/O. DeviceLogix-enabled I/O performs simple control functions locally without the performance constraints typically imposed by a centralized controller and a communication network.
Rockwell Automation also offers distributed safety I/O modules, including I/O that can be located on the machine close to sensors and actuators, controlled from a safety PLC. A distributed safety I/O module continuously monitors its internal functions to make certain that it is functioning and available if a safety demand is placed on the system. It also provides valuable detailed diagnostic information to the machine operators and maintenance personnel making troubleshooting easier and thereby improving overall machine utilization.
