ABB 07DI92 Digital Input Module

Product Overview

The ABB 07DI92 module serves as a remote digital input module for the CS31 system bus. It offers 32 digital inputs, all operating at 24 V DC. The module divides these inputs into four groups, each electrically isolated to prevent interference. This feature ensures the module performs consistently and safely in industrial environments, even in the presence of electrical noise.

Key Features

32 Digital Inputs: With 32 digital inputs, the module allows flexible configuration for various applications. Each input group operates at 24 V DC, and electrical isolation ensures that no cross-interference occurs between them.
Electrical Isolation: The four input groups are fully isolated from each other and from the main unit, offering superior protection from electrical disturbances. Additionally, the CS31 system bus connection remains isolated to prevent potential issues with signal integrity.
Dual Addressing: The module uses two digital addresses for inputs on the CS31 system bus, simplifying configuration and communication between modules.
Real-time Status Monitoring: The front panel features 32 green LEDs, which indicate the signal status of each input. This visual feedback allows operators to monitor inputs in real time.
Error Detection: Three red LEDs light up to signal any errors, helping users identify and resolve issues quickly.
Test Functionality: The test button provides a quick way to check system performance without needing additional tools.
