2 Channel 12V Relay Module Solid State High Level SSR DC Control 250V 2A with Resistive Fuse

This is a 2 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.

A Solid State Relay is similar to 2 Channel 12V Relay Module Solid State High-Level SSR DC Control 250V 2A with Resistive to a mechanic relay where it can be controlled through a digital signal. Solid State Relay generates no noise and has a much longer lifespan compared to the traditional mechanic relay.

1. DC+: connected to VCC (Supply power according to relay voltage)
2. DC-: connected to GND
3. CH1: relay module signal trigger point (Effective high-level trigger)
4. CH2: relay module signal trigger point (Effective high-level trigger)
