ABB DI801 Digital Input Module

Description

The ABB DI801 Digital Input Module is a dedicated I/O component designed for use with the S800 I/O system, a distributed modular process I/O platform compatible with various industrial process controllers. This module features 16 digital input channels configured in a single isolated group, with channel 16 available for voltage monitoring within the group. It supports a DC input voltage range of 18 to 30V, drawing 6mA of current at 24V, and operates with a current sink signal type. Each input channel integrates a current-limiting component, EMC protection component, input status indicator LED, and optoelectronic isolation barrier to ensure reliable performance and signal integrity. Key features include individual channel status visualization via built-in LEDs, simplified wiring and maintenance through a detachable connector for process and power connections, and robust channel isolation to minimize cross-channel interference. Ideal for industrial control systems, the module is engineered to interface with digital signals from devices such as switches, buttons, limit switches, and proximity sensors, supporting efficient data collection for automated process operations. Its official article number is 3BSE020508R1.
