Analog Outputs Setup


In case you don't intend to control voltage at your SM2-AD module's analog output, go to Next >>

Open menu „System Setup / Outputs“ in your web browser.

We set up analog output in the same way as digital outputs. Select the factor determining the output setup (e.g. temperature in the room with inverters, PV plant's production).

1st example: Regulation of Ventilation Revolving
Set up the temperature range corresponding to value 0 - 10 V at the output. The temperature is going to determine ventilation revolving.

I.e.:
y = the number of Volts in the range from 0 (V) to 10 (V) that output will deliver with a given temperature range
given temperature range: x1 = minimum (°C) to x2 = maximum (°C), e.g. 15 - 40 °C
x = current temperature in the room (°C), e.g. 28 °C

y = [10 / (x2 - x1)] * (x - x1)
y = [10 / (40 - 15)] * (28 - 15)
y = 5,2 V


2nd example: Charging Storage Battery
Set up PV plant's production range corresponding to the value 0 - 10 V at the output. This will determine charging the storage battery.

I.e.:
y = the number of Volts in the range from 0 (V) to 10 (V) that output will deliver with a given PV plant's production range
given PV plant's production range: x1 = minimum (W) to x2 = maximum (W), e.g. 2500 - 10000 W
x = current PV plant's production (W), e.g. 5200 W

y = [10 / (x2 - x1)] * (x - x1)
y = [10 / (10000 - 2500)] * (5200 - 2500)
y = 3,6 V
