When receiving a wet-contact input
The system receives a voltage-type signal from an external device. When the output of an external
device is a source type, it receives 24V/0V voltage as input. When the output of the external device
is a sink type, it can receive 24V/0V voltage as input with the addition of a relay. Since voltage input
needs a base, it must be connected through a common ground to the externally connected power.
