In-Cabinet Distributed I/O
In-Cabinet (IP20) distributed I/O requires an enclosure for environmental protection, and is available in modular, block, and safety 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. Safety block I/O can be used with Rockwell Automation safety controllers, to communicate on DeviceNet using CIP Safety.
