It supports a 3.3-5V DC control signal to control a single-phase 220-250V AC power output. Combined with the M5 controller and the UIFlow programming platform, it can easily achieve remote control. Compared to ordinary mechanical relays, this solid-state relay uses power semiconductor devices for control, offering microsecond-level switching speed and built-in overcurrent protection. It has no physical contacts, long lifespan, high reliability, and can adapt to complex working environments such as severe vibrations. It is used in scenarios requiring frequent switching and fast response, such as lighting control and CNC machine tools. Note 1. Be cautious when using high-voltage AC loads; do not operate with power on. 2. This relay is only suitable for AC loads. Features Zero-crossing SSR Built-in overcurrent protection Built-in optocoupler isolation with zero-crossing detection Fast speed, low noise, long lifespan, high reliability, and high sensitivity Uses GROVE interface for easier connection Supports UIFlow graphical programming, enabling remote control of the relay with an M5 controller in just 3 minutes Advantages of Solid-State Relays over Mechanical Relays: 1. Faster switching speed with no physical contact wear. 2. Completely silent operation. 3. No electrical sparks, suitable for complex environments. 4. Longer lifespan. 5. Smaller size.
