Input signal is a mechanical contact switch, normally open type and closed type are all
supported, it is effective when it is connected to 24VG
，
and it is ineffective when it is
float or connected to 24V. Com-port of switch outside is connected 24VG. The other
port is connected to corresponding IO port.
