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

The B&R 3DI475.6 DI475 Digital Input Module delivers 16 24 VDC digital inputs in a System 2005 single‑width format, designed for either sinking or sourcing wiring and arranged in four electrically isolated input groups for robust multi‑point signal acquisition. It draws a total of 1.5 W and uses a nominal 24 VDC input supply, with hardware input filtering specified at ≤12 ms and per‑channel I/O status indicators to verify operation. The module is IP20 protected, operates from 0 to 60°C with 5–95% relative humidity, and is field‑installable on a System 2005 base or expansion unit. Key specifications include 16 inputs at 24 VDC, four isolated input groups, and electrical isolation between groups, along with CE, UKCA, and UL (cULus E115267) certifications. The 3DI475.6 is compatible with TB170 terminal blocks (sold separately), with options such as 3TB170.91 (20‑pin, push‑in) or 3TB170.9 (20‑pin, screw clamp) to terminate field conductors. Typical applications involve digital signaling from sensors, switches, and other 24 VDC devices in industrial automation, process control, and machine control environments, where sink or source wiring flexibility and isolated input groups help reduce interference and improve reliability. Measurements and mounting align with System 2005 standards, enabling straightforward integration into existing B&R control architectures and expansion schemes.
