The ABB DI724F is a digital input module that is part of the ABB AC 800F remote I/O system. It is designed to interface between digital sensors and a control system in an industrial automation application. The module has 32 channels of 24 V DC digital inputs that are divided into four groups. The inputs are electrically isolated from the other electronic circuitry of the module, and there is no potential separation between the channels. The DI724F module is suitable for use with PROFIBUS DP remote I/O applications.
