B&R Industrial Automation 3DI476.6 Digital Input Module

3DI476.6 is a 16-channel digital input module for B&R System 2005 that accepts 24 VDC signals and provides fast, deterministic sensing with a hardware input filter of 1.2 ms, wired as either sink (NPN) or source (PNP). It features four electrically isolated input groups, per-channel status indicators, and a base/expansion-ready 1-slot, single-width footprint, with TB170 terminal blocks ordered separately. Electrical specs include nominal 24 VDC inputs and a total power draw of 1.5 W (5 V logic); the module complies with IP20 protection and operates from 0 to 60°C with 5 to 95% relative humidity (non-condensing). Physical dimensions are 80 mm wide, 20 mm high, and 150 mm long, weighing about 0.39 kg, and it is designed to mount on B&R backplanes within the System 2005 family as both a base and expansion module. Certifications include CE, UKCA, and UL (cULus), ensuring suitability for industrial environments where 24 VDC digital inputs are used to monitor sensors, switches, and other field devices connected to automation systems.
