Distributed I/O
In-Cabinet
Overview
Distributed I/O can be mounted In-Cabinet (IP20), requiring an enclosure, or On-Machine™ (IP67/69), not requiring an additional enclosure for environmental protection and allowing easier maintenance. Both Distributed I/O types are offered 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.
