C.3 Digital Binary (dry-contact, switches) Sensor Interface P/N DIG_DIY1
The Digital binary 1/0 is a common industrial signal that indicates ON/OFF states of machines,
motors, valves, open/close doors, and more. The
Datalog X-PRO Digital Two Inputs Binary
Interface (DIG-DY1)
easily takes digital states, counts the quantity of events, and can be
programmed to send an alert when a detected state changes.
