A module with two PC817 optocouplers. Allows you to add galvanic separation in the form of opto-isolation between electrical circuits
Module with a 12 V relay and a timer. It allows you to turn the device on and off cyclically at a specified time using potentiometers. It can also operate in single trigger mode, which allows the device to be turned on after a signal has been applied for a specified period of time. The operating time can be adjusted from 1 s to 100 s or from 1 s to 15 min
The remotely controlled modulation module MOD-34 / AZ allows wireless load control with up to 10 A current consumption via a relay. It does not contain nRF24l01.
