EtherNet/IP I/O Platforms
In-Cabinet Distributed I/OIn-Cabinet (IP20) distributed I/O requires an enclosure for environmental protection, and is available in modular and safety block I/O styles. Modular I/O is a system of interface cards and communications adapters that interface directly to the sensors and actuators of the machine/process and communicate their status to the controller via a communication network. It allows the designer to mix and match I/O interfaces and communications adapters. Safety block I/O can be used with Rockwell Automation safety controllers.

On-Machine Distributed I/O
On-Machine (IP67) distributed I/O does not require an additional enclosure, allowing for easier maintenance. On-Machine I/O is available in modular and block I/O styles. Modular I/O is a system of interface cards and communications adapters that interface directly to the sensors and actuators of the machine/process and communicate their status to the controller via a communication network. It allows the designer to mix and match I/O interfaces and communications adapters. Block I/O is a complete assembly of sensor and actuator interface points including a network adapter. It may or may not include a power supply and is available in fixed configurations.

Chassis-based I/O
Chassis-based I/O is specifically designed for a particular controller, as part of its family. Allen-Bradley chassis-based I/O systems are also capable of being mounted away from the controller via networks.
