Digital Input
The system provides 1 digital input in the bottom side of the device.
It allows users to connect the termination units’ digital output and manage/monitor the status of
the connected unit. The Digital Input pin can be pulled high or low; thus the connected equipment
can actively drive these pins high or low. The embedded software UI allows you to read and set
the value to the connected device. The power input voltage of logic low is DC 0~10V. Logic high
is DC 11~30V. Wiring digital input is exactly the same as wiring power input.
2.3.6
Digital Output
The system provides 1 digital output. It is also known as Relay Output. The relay contacts are
energized (open) for normal operation and will close for fault conditions. The fault conditions
include power failure, Ethernet port link break or other pre-defined events which can be
configured in the management interface. Wiring digital output is exactly the same as wiring power
input.
