Relay (Digital Output)
The AWK-3121 has one relay output, which consists of the 2 terminal block contacts on the top
panel, as shown below. These relay contacts are used to forward system failure and
user-configured events.
The two wires attached to the relay contacts form an open circuit when a user-configured event is
triggered. If a user-configured event does not occur, the relay circuit will remain closed. For safety
reason, the relay circuit is kept open when the AWK-3121 is not powered.
