B&R Industrial Automation 2DI426.6 Digital Input Module

The B&R 2DI426.6 digital input module provides 32 inputs at 24 VDC with a 1 ms response time, organized in eight electrically isolated input groups and configurable for sink or source wiring. It is designed for B&R System 2010 backplanes (BP200, BP201, BP210) and requires TB140 terminal blocks to be ordered separately for field connections. Electrical specifications include nominal 24 VDC input, a maximum of 30 VDC, ~4 kΩ input resistance, and switching thresholds of <5 V for LOW, 5–15 V for MID, and >15 V for HIGH, with a typical input delay of 1 ms and a maximum around 1.2 ms; power consumption up to 6 W. The DI426.6 provides isolation between groups and from the backplane, supporting safe operation in industrial environments.
