This controller was designed to provide a solution in the installation of a refrigeration project. The controller has two sensors which measure the temperatures. The temperature difference is calculated and the difference is converted to an analogue voltage in the range of 0 to 10 Volts. This analogue control is often used on various inverted controllers, variable frequency drives and so forth. In addition, a three-channel fan speed output was also added to the design. The switching is performed by heavy-duty 20Amp Relays. The power supply is encapsulated to keep it safe on the board and also an RGB Led onBoard shows all the status.
I needed to interface an inverter controller in a project. After spending two days looking for such a controller, I finished designing my own as I did not find what I needed!
The Controller has these features :
The controller has the following cycle states
On Bootup: The LEDs cycle Blue - Red - Green - Blue and goes to standby.
On Standby: The led stays Green.
If a sensor is not detected then :
On Dry contact Switch closed: Led's cycle Rainbow Colours and analogue output goes to Maximum voltage 10v for 20 seconds. After this cycle, the controller will measure the sensors and the difference is outputted as a voltage as follows :
|Temperature Difference||Led Colour||Analogue Voltage|
|0 to 3||yellow||1v|
|4 to 5||orange||2v|
|6 to 7||green||3v|
|7 to 11||cyan||4v|
|11 to 15||blue||5v|
|16 to 21||marquee||6v|
|22 to 25||pink||7v|
|26 to 2||purple||8v|
|28 to 29||red orange||9v|
