PRODUCT INFORMATION
Product Overview
The ABB DI811 3BSE008552R1 is a 48 V d.c. Digital Input Module designed for the S800 I/O system. It provides 16 current sinking digital input channels arranged in two individually isolated groups of eight. Each channel incorporates optical isolation barriers, current limiting components, and individual state indication LEDs. In addition, built-in process voltage supervision monitors field supply integrity and flags voltage loss via the ModuleBus interface.
This module features selectable digital filter times of 2, 4, 8, or 16 ms. It dissipates 2.7 W typically and draws 50 mA from the 5 V ModuleBus supply. The unit mounts onto standard S800 Module Termination Units using mechanical keying code BD. Field wiring lengths can extend up to 600 meters under compliant installation practices.
