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 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.
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.
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.
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.
Our On-Machine™ Block (IP67/69K) Distributed I/O modules can be mounted directly on a machine rather than in a remote, central cabinet, which reduces wiring costs and provides easier maintenance. These products provide a complete assembly of sensor and actuator interface points, and each module includes a network adapter. Expansion blocks are available for some products. You can choose from analog, digital, and specialty I/O modules, as well as On-Machine I/O modules for safety systems.
Our Bulletin 1738 ArmorPOINT® I/O modules provide a wide range of input and output modules to span many applications, from high-speed digital to process control. ArmorPOINT I/O supports producer/consumer technology, which lets input information and output status to be shared among multiple Logix controllers.
