4.2.3 Digital Input Setup
The AcuLink 810 has 8 Digital Input channels. Each Digital Input can be used as an input
pulse counter.
Each channel has two terminals, a DI terminal and a DI COM terminal. In pulse output cir-
cuits a closed loop is required for the pulse to be generated. In the Image below you will see
a closed circuit on Digital Inputs 1 and 6. The positive output is connected to the DI channel
input and negative output is connected to the DI Common input.
