ABB DI801 High-Performance Digital Input Module
Description
ABB DI801 High-Performance Digital Input Module is an industrial-grade digital input module designed for harsh automation control environments. It reliably collects field switch signals such as limit switches, buttons, and relay contacts, converting them into logic levels recognizable by control systems to enable accurate monitoring and feedback of equipment operating status. It is part of the ABB S800 I/O series, supporting flexible integration with mainstream control systems.
