ABB DI818 Digital Input module

The ABB DI818 is a digital input module designed to be used with ABB's AC 800M and AC 800PEC controllers. It provides 8 input channels, which can be used to read the state of digital signals such as switches, relays, or other devices that provide a discrete on/off signal.

The DI818 module supports a wide range of input signal types, including DC voltage, DC current, and various types of AC signals. The input channels are isolated from each other and from the controller to provide protection against electrical noise and interference.

The module is hot-swappable, which means that it can be replaced while the controller is running, without the need for shutting down the system. It also has LED indicators to display the status of each input channel.

The DI818 module is typically used in industrial automation applications, such as process control, factory automation, and machinery control. It is part of ABB's extensive range of control system products and solutions, which are designed to provide reliable and efficient control of industrial processes and equipment.
