NC (normal closed): The signal loop is closed under normal conditions. When the loop
becomes open, DI will be triggered until the loop becomes closed again. In other words, if
the loop keeps on open for a period of time, DI will keep on triggering in that time
interval.
♦
NO (normal open): The signal loop is open under normal conditions. When the loop
becomes closed, DI will be triggered until the loop becomes open again. In other words, if
the loop keeps on closed for a period of time, DI will keep on triggering in that time
interval.
