A solid-state relay (SSR) functions like a mechanical relay but uses infrared light as the contact, providing advantages such as noise-free operation and a longer lifespan. It can be controlled through a digital signal and switched at lower voltages and currents than mechanical relays. With no moving contacts, SSRs offer faster and more durable switching capabilities.
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)
