Digital input applications
They can also be used for pulse counting or input metering applications, such as WAGES (water, air, gas, electricity, steam) monitoring, or conditional energy applications, or IRIG-B time synchronization.
! Example only to show how we can start reusing sections from existing topics in Motif, for example graphics from ION Reference.
If you set Input Mode to PULSE, a pulse is generated at the Trigger output when the State output changes from OFF-to-ON. No pulse is generated when State changes from ON-to-OFF.
If you set Input Mode to KYZ, a pulse is generated at the Trigger output for each change of state transition, i.e. from OFF-to-ON and from ON-to-OFF transitions.
If you set Input Mode to A/C, the digital input port is configured to detect the presence of a low voltage AC signal. The next illustration shows how a digital input can be used to monitor the operation of a low voltage AC fan controller.
