Digital Input/Output
A digital output opens or closes the circuit between two terminals depending on the
binary state of the output. A digital input is a switch and a voltage sending device.
Depending on the switch's open/closed status, Unimax+ detects a voltage or no
voltage condition, which in turn generates a logical 0 or 1, ON or OFF, alarm or normal
or similarly defined state.
