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 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. One such advantage is that they can be switched by a much lower voltage and at a much lower current than most mechanical relays. Also, because there are no moving contacts, solid-state relays can be switched much faster and for much longer periods without wearing out.
Input Parts:
- DC+: connected to VCC (Supply power according to relay voltage)
- DC-: connected to GND
- IN1: CH1 Signal triggering the end of 1-channel relay module (active at the high level)
- IN2: CH2 Signal triggering the end of 2-channel relay module (active at the high level)
- IN3: CH3 Signal triggering the end of 3-channel relay module (active at the high level)
- IN4: CH4 Signal triggering the end of 4-channel relay module (active at the high level)
Use it to control various appliances and other equipment with a large current. It can be controlled directly by a Microcontroller. Input control signal voltage: 0-0.5V low stage SSR is OFF, 0.5V-2.5V (unknown state), 2.5-20V high stage SSR is ON.
