Beam.
Redundant Power Inputs
Both power inputs can be connected simultaneously to live DC power sources.
If one power source fails, the other live source acts as a backup, and
automatically supplies all of Moxa Industrial Media Converter’s power needs.
Alarm Contact
Moxa Industrial Media Converter has one Alarm Contact located on the top panel.
For detailed instructions on how to connect the Alarm Contact power wires to the
two middle contacts of the 6-contact terminal block connector, see the “Wiring the
Alarm Contact” section above. A typical scenario would be to connect the Fault
circuit to a warning light located in the control room. The light can be set up to
switch on when a fault is detected.
The Alarm Contact has two terminals that form a Fault circuit for connecting to an
alarm system. The two wires attached to the Fault contacts form an open circuit
when (1) IMC has lost power from one of the DC power inputs, or (2) one of the
ports for which the corresponding PORT ALARM Dip Switch is set to ON is not
properly connected.
If neither of these two conditions occurs, the Fault circuit will be closed.
