Question

I plan to connect the device into a 12V solar system battery.

PIN 1 is +12V and PIN 2 is ground.

For what are PIN 3 input and PIN 4 output used for and can I leave them empty? And if not what am I supposed to connect there?

Answer 1

Hi,

Input	1 x Digital non-isolated input (on 4 pin power connector)
Output	1 x Digital open collector output (30 V, 300 mA, on 4 pin power connector)

 

3rd pin is the input, and the 4th pin is the output.
