B&R DI426 Digital Input Module
The DI426 is a designation commonly associated with a digital input module used in industrial control systems to read binary (on/off) signals from field devices such as switches, pushbuttons, limit switches, and sensors. The DI prefix typically denotes digital input, and modules with this designation bring discrete field signals into the control system for processing by the CPU.
- Digital input module designation
