B&R Industrial Automation 3DI475.6 Digital Input Module

The B&R 3DI475.6 is a 16-channel digital input module for B&R System 2005 backplanes, delivering 16 24 VDC inputs in four electrically isolated input groups for fault containment. It supports sink or source wiring and uses a hardware input filter of ≤12 ms to debounce signals in industrial environments. The module fits in a System 2005 single-width slot and can be mounted on the base unit or expansion units, with the 1x TB170 terminal block ordered separately. Electrical isolation exists between groups (group-to-group), while channels within the same group share isolation. Power consumption is 1.5 W total, with 5 V logic supply drawing 1.5 W; nominal input voltage is 24 VDC. Operating conditions are 0 to 60°C and 5 to 95% relative humidity (non-condensing), with IP20 protection. Certifications include CE, UKCA, and UL/cULus, and the device carries the part number 3DI475.6 as a 2005 digital input module described as 16 inputs at 24 VDC with a 12 ms response across four isolated groups.
