The Network Hour Meter was created with ease-of-use in mind. The Network Hour Meter (NHM) may be activated in a number of different ways. In the simplest setup the Network Hour Meter may be activated whenever power is applied to the unit. In this case, if the Network Hour Meter is on, it is counting. A voltage threshold is provided so the Network Hour Meter may stop counting as power is lost to prevent memory corruption.
You may also use one of the inputs to turn counting on and off. The input can be configured with an internal pullup so that a switch may be used, or an external voltage of 5-24 VDC may be used.
Alternatively it can be configured to follow one of the relays such that when the relay is activated the Network Hour Meter will count.
If you want to receive audible or visual notifications when a specific hour is reached, connect a buzzer or light to the a relay output of your Network Hour Meter. The Network Hour Meter can now record your equipment run time once you start your equipment and turn the buzzer or light on when maintenance is required.
