The ABB 3BSE066490R1, also known as the DI828 Digital Input Module, is a key component of the S800 I/O system, designed for seamless integration with ABB’s Ability™ System 800xA. This module features 16 channels for 24 V d.c. digital inputs and is specifically engineered for use in redundant applications, ensuring high availability and system reliability. Each channel is galvanically isolated from the ModuleBus, enhancing safety and signal integrity. The DI828 provides clear status indication for each input via front-panel LEDs and connects to the process through a detachable connector on the required Module Termination Unit (MTU), making it a versatile and dependable solution for industrial process control and automation.
