Input/Output (I/O) Modules

Left facing Allen-Bradley FLEX 5000 I/O standard and safety modules, Bulletin 5094

Allen-Bradley I/O is available in a variety of sizes and point densities, providing the flexibility you need to fit your exact requirements.

Choose from chassis-based I/O that is integrated with your Allen-Bradley controller, or I/O that is distributed around your application or mounted on a machine. For distributed applications, we offer in-cabinet (IP20) and hardened on-machine (IP67/69K) options, in both modular and block designs. Several I/O families feature DeviceLogix™ Smart Component Technology, integrating low-cost logic solving capability in your I/O. For safety solutions, our Guard I/O™ products are TÜV-certified up to SIL 3, Cat. 4, PLe. Communication support includes DeviceNet^®, ControlNet^®, and EtherNet/IP™, plus other industrial networks.

Chassis-Based I/O

Chassis-based I/O is specifically designed for a particular Allen-Bradley® controller, as part of its family. You can install the I/O locally in the same chassis as the controller. Additionally, through the use of I/O communication networks, you can distribute the I/O closer to the sensors and actuators, reducing your wiring costs.

Embedded I/O Modules

Our Bulletin 1799 Embedded Distributed I/O Modules provide a standard interface between an input device and machine actuators. You can leverage our proven design technology and reliability without the cost of custom‑packaged solutions—critical for cost-sensitive machine-embedded applications. An available expansion board and universal I/O reduce your initial material investment, minimize inventory, reduce cost per I/O expansion, and maximize I/O use for each application.
