Standard Power and Current Readings
In a healthy system you should see power and current readings for the 2-wire path with the approximate
values:
Idling
Heavy Usage
(many stations running)
Current
0-3mA (no stations attached) 300-600mA
To check power and current readings, refer to the instructions on Page 30.
To get a more precise idea of what your current reading should be, you should add the standby usage plus
the running usage using the following guidelines:
Standby Usage
When no valves are running, all connected stations will consume around 0.5mA each. It is normal to see idle
consumption in the 0.4-‐ 0.65mA range.
For example, 20 connected stations will consume around 8-13mA, and 100 units will consume 40--65mA.
Note that this will be true even if there is nothing connected to the output wires of the decoder. Each
decoder all by itself draws 0.5 mA.
Active Stations
When active, any station, controlling a valve or master valve, will consume around 15-35mA. This means that
when running just one station or a master valve on a system with 96 connected units, you may use around
115-140mA. Note that these numbers are valid for decoders set to normal power. If you change the power
settings, the numbers will change. The higher the power setting, the higher the current reading.
