Shield of relays for Arduino, with 2 channel mechanical relays and with 2 channel MOS switch , providing an easy way for applications low and high voltage control. 

The MOSFET power controller is a module that can drive a large current device with current limited GPIO a. It works as a MOSFET relay or MOSFET driver. When providing a high level digital signal (3.3 - 10V), the MOSFET is enabled or disabled.

8 relay module with ports " NC " means " Usually connected to COM " and ports "NO" means " Usually open to COM ".

The Hexa base rotation kit is perfect for rotating a large mass. It can easily support 5kg . It is injection molded from ultra strong ABS plastic .

A Universal Relay Board Kit with 16 Relays and Connectors included! Transformer included. The 12V DC output can be used as a power supply for other kits. Each outlet can be equipped with a noise suppressor.

Relay, as its name implies, implements a relay function. The relay can be used as a switch operated electrically through the coil to mechanically operate a switch, where it is sometimes necessary to control a circuit of another voltage and current load through a separate low power signal, such as a digital signal emitted by a mircoprocessor. Up to 30V DC and 220V AC.

Mini Relay with 6V Output, Dual Channel.
