Description
| 4-channel shield with 5V relays, designed to be compatible with the Arduino UNO R3 and R4 boards. This module lets you switch high-current devices such as household appliances. Each relay is driven by a HIGH signal and can handle loads up to 120V AC/3A or 24V DC/3A.
The KS0251 has four relays, wired respectively to digital pins 4, 5, 6 and 7 of the Arduino board. When one of these pins is set HIGH, the corresponding relay pulls in and its indicator LED lights up. The shield has a standard interface that allows a direct connection to microcontrollers. Easy to fit and easy to use, this shield is ideal for home automation projects and for remote control of devices. |
