NavNet port voltage, current capabilities & alarm

General

Question

​What is the maximum NavNet port voltage and current capabilities? Also what is the maximum current available for the alarm port using an external buzzer or relay?

Solution

​The maximum voltage output and current capabilities for the NavNet display ports that supply voltage output is 12 volts DC at 300 mA. However if more current capability is needed, use an appropriate relay as a contact closure for any externally supplied voltage requirements. The maximum current output from the alarm port is 100 mA.
