DI821 3BSE008550R1 ABB Digital Input 230V 8 ch

Description

The DI821 3BSE008550R1 is a digital input module from ABB, part of the S800 I/O series. It features 8 channels and is designed for 230V AC input operation, with a rated working voltage of 220V and compatible with 50Hz frequency. The module carries CE certification and is not available for custom processing. As a front-end signal acquisition component, its core function is to receive external digital signals, such as switch status signals, and convert them into system-recognizable signals to enable monitoring and control of automated systems. It accurately detects changes in external device status and transmits this data to the control system, ensuring stable operation of the entire automated workflow. This module is widely applied in industrial automation and process control fields, serving as a reliable component for integrating field-level digital signals into upper-level control systems. It is originally manufactured in Switzerland, with its model number and order code both designated as DI821 3BSE008550R1.
