ControlNet I/O Platforms

In-Cabinet Distributed I/O

In-Cabinet (IP20) distributed I/O requires an enclosure for environmental protection, and is available for ControlNet in the modular I/O style. 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.

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 for ControlNet is available in the modular I/O style. 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.

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.
