Q: power input 7-32V what is + and -

尋ねた Tellus に 2022-05-02 07:42:38

kkam54 You have two power inputs for the electronics: 5 VDC USB power input and 7-32 VDC_VAC power input. So, in the end, the board is probably powered from 5 VDC. The connection method to the terminals marked as "Power input 2 DC_AC 7-32 V" does not matter.

kkam54 This device is equipped with a 3A relay. I suggest adding a typical contactor that will protect the remote device and extend the operation time of the internal relays.

Q: Is there a manual ?

kkam54 The box only contains a Quick Guide with basic information and a QR code for the manual on Dropbox but I was unable to access this file. In my opinion, the commands are typical for this type of device.
