The AFP standard has 20 inputs and 20 outputs. It is our workhorse, designed for the main control functions in your greenhouse.
The 20 inputs are divided over the different types as follows: 10 analogue inputs, 4 counter inputs and 6 digital inputs.
You can use the analogue inputs easily with all normal signals from greenhouse sensors like temperature, humidity, pH, EC. You need this input for a good regulation.
They can read the signal as 4-20 mA or as 0-3 V signal, most sensors on the market have one of these two ranges. But the AFP can also read in the ranges of 0-4 mA, 0-10V etc.
We provide the outputs as NC (normally closed). But for five you can also switch to NO (normally open).
