B&R 7DI140.70 Digital Input Module
The B&R 7DI140.70 is a digital input module from the B&R SYSTEM 2003 / 2005 I/O range. The 7DI prefix marks it as part of B&R's digital input module family, used to read binary on/off signals from field devices such as switches, pushbuttons, limit switches and sensors. Installed in the modular I/O rack, it brings these discrete signals into the B&R control system for processing by the CPU.
