ABB DI810 Digital Input Module DI810

Description:

The ABB DI810 digital input module is used in industrial automation systems to receive and process 24 VDC discrete signals from field devices such as sensors and switches. Commonly installed in ABB PLC racks and control cabinets to interface field‑level inputs with the automation controller. Maintenance teams and system integrators use this module for I/O expansion, system upgrades, and replacement of failed or outdated input modules.

Applications:

The ABB DI810 is widely used in factory and process automation environments requiring reliable monitoring of discrete input status. It is commonly found in conveyor systems, packaging lines, material handling equipment, safety interlocks, and assembly machines where 24 VDC signals from proximity sensors, pushbuttons, or limit switches are needed to trigger logic control and monitoring functions.
