WIRING THE ALARM RELAY OUTPUT (DO)
The relay output contacts are located on the front panel of the switch. The relay output consists of the 2-pin
terminal block connector that used to detect user-configured events. The two wires attached to the fault contacts
form a close circuit when a user-configured event is triggered. If a user-configured event does not occur, the fault
circuit remains opened. The fault conditions such as power failure, Ethernet port link break or other pre-defined
events which can be configured in the switch. Screw the DO wire tightly after digital output wire is connected.
NOTE:
The relay contact only supports 0.5 A current, DC 24V. Do not apply voltage and current higher
than the specifications.
