ABB DI814 Advanced Digital Input Module for Automation

Description

TheDI814 Digital Input Moduleis part of ABB’s S800 I/O system, which integrates withSystem 800xAandAC 800M controllers. It provides16 channelsfor 24 VDC digital inputs, divided intotwo isolated groups of eight channels each, with one voltage supervision input per group. This design ensuresfault detection, galvanic isolation, and reliable signal acquisition from field devices such assensors, switches, and interlocks. Moreover, each input channel includescurrent limiting components, EMC protection, optical isolation, andLED indicatorsfor state monitoring. The module reportserror signals through the ModuleBusif voltage supervision detects a fault, enhancing system diagnostics and reliability.
