1 channel 12V 30A Relay Control Board Module with Optocoupler
1 Channel 12V Relay Module Solid State High Level SSR DC Control 250V 2A with Resistive
1 Channel 12V Relay Module Solid State Low Level SSR DC Control 250V 2A with Resistive Fuse
This is 1 Channel 12V Solid State Relay Module. A solid-state relay (SSR) is just what it sounds like an IC that acts like a mechanical relay. They allow you to control high-voltage AC loads from lower voltage DC control circuitry. They accomplish this by using infrared light as the contact, a solid-state relay is really just an IR LED and a photo Triac sealed up into a little box. Solid-state relays have several advantages over mechanical relays.

1 Channel 3-24V Relay Module Solid State High Level SSR DC Control DC with Resistive Fuse
1 Channel 3-24V Relay Module Solid State Low Level SSR DC Control DC with Resistive Fuse
Low-level trigger refers to the signal triggering voltage between the end and the negative electrode of the power supply is OV, or trigger terminal voltage lower voltage than the positive power supply voltage, low to can trigger, make the relay, is usually the cathode of the power supply and the triggering end of a trigger mode connection, so that the relay is attracted.
1 Channel 5V SSR G3MB-202P Solid State Relay Module with Resistive Fuse
12V 1 Channel Bluetooth Control Relay Module
The DC 12V 1 Channel Bluetooth Wireless Control Relay Module contains 2 relay channels that operate on 12VDC to handle the appliances of 230VAC or 30VDC up to the 10A current. The relay module comes with an onboard integrated SPP-C Bluetooth serial slave module, which can be used to control relay switching by sending commands via the mobile phone APP with very easy to set up.
