Input/Output (I/O) Modules

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

Chassis-Based I/O

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.

Distributed I/O, In-Cabinet Modular

In-Cabinet Modular Distributed I/O

In-Cabinet (IP20) distributed I/O can be placed throughout your application and requires an enclosure. Our In-Cabinet Modular I/O products let you select the exact mix of I/O interfaces and communication adapters to fit your needs, providing greater flexibility in designing your system. In addition to a wide range of analog, digital, and specialty modules, we provide in-cabinet I/O options for extreme environments, I/O for safety systems, and intrinsic safety (IS) I/O that can be distributed throughout hazardous areas.

Distributed I/O, On-Machine Modular

On-Machine Modular Distributed I/O

On-Machine (IP67/69K) distributed I/O can be mounted directly on a machine rather than in a remote, central cabinet, reducing wiring costs and allowing for easier maintenance. Our On-Machine Modular I/O solutions let you select the exact mix of I/O interfaces and communication adapters to fit your needs, providing greater flexibility in designing your system.

Distributed I/O, In-Cabinet Block

In-Cabinet Block Distributed I/O

In-Cabinet (IP20) distributed I/O can be placed throughout your application and requires an enclosure. Our In-Cabinet Block I/O products provide a complete assembly of sensor and actuator interface points, and include a network adapter. Expansion blocks are available for some families. Choose from a wide range of analog, digital, and specialty I/O, as well as I/O for safety systems.

Distributed I/O, Embedded

Embedded Distributed I/O

With embedded I/O, you can buy just what you need to develop your machines. Quickly incorporate off-the-shelf printed circuit boards into your development cycle and save costs associated with providing panels and existing enclosures. Cards include built-in DeviceNet™ or EtherNet/IP™ network support. Optional DeviceLogix™ Smart Component Technology on DeviceNet cards increase response time and help reduce network traffic. EtherNet/IP cards feature embedded switch technology and support device-level ring (DLR) topology, providing added cost savings and redundant communications for improved system availability.
