Product Overview
The ABB DI811 3BSE008552R1 is a 16-channel, 24 V DC isolated digital input module within the renowned ABB S800 I/O series. It is engineered to provide high-performance digital input signal acquisition for distributed control systems such as ABB 800xA and AC 800M.
The DI811 is notable for its channel-to-channel isolation, which ensures increased reliability and signal integrity in systems exposed to electrical noise or needing signal separation. Each input channel is electrically isolated, enhancing safety and system modularity. The module connects to field devices through compatible terminal 台s such as TU810V1, TU812V1, and TU830V1, /fering flexible wiring options.
