The left picture in Fig.3 shows an example of digital input (DI) dry contact in which the digital input channel is controlled by a switch
that is wired to the COM pin of the DI port. An external DC power(9~36V) is supplied this external circuit via the wiring of DI pin and
the switch. The position of switch and power supply can be interchanged.
The right picture in Fig.3 shows an example of digital input (DI) wet contact in which the digital input channel.
