Description Unit DCSSR is a DC-to-DC single-phase solid-state relay controller kit, which includes a single-phase solid-state relay + ESP32C3 core control board. It supports three working modes: button control, I2C slave, and Modbus networking. The integrated programmable full-color RGB LED can be used for various status indications. Compared to traditional mechanical relays, this relay is a contactless switch assembled and solidified using semiconductor components. It has a series of advantages such as fast switching speed, high operating frequency, long service life, low noise, and reliable operation without sparks. It is commonly employed in digital program-controlled devices, motor control devices, temperature control devices, data processing systems, and computer terminal interface circuits, and is particularly well-suited for special occasions with frequent actions, explosion-proof, moisture-proof, and corrosion-resistant requirements. Features Single-phase solid-state relay Three working modes: Button control I2C slave (supports device I2C address configuration) Modbus networking (supports device ID configuration) Programmable full-color RGB LED RS485PWR interface (supports 9-24V device power supply) Includes 1x Unit DCSSR 1x Single-phase solid-state relay 2 x 3.96-4P terminal blocks 1 x HY2.0-4P Grove connection cable (20cm) 1 x Communication protocol manual Applications DC circuit on/off Motor equipment control Temperature control equipment Specifications Specification Parameter Controller MCU ESP32C3 Communication Interface I2C @0x50 Programmable RGB LED SK6812 Load Current 10A Input Control Voltage DC 3 ~ 32V Load Voltage DC 24 ~ 220V Input Control Current 5 ~ 20mA Off-state Leakage ≤5mA On-state Voltage Drop ≤1.6V Safe Operating Current Resistive load: 50% Inductive load: 50% Electrical Life ≥1 million times Indicator Light Red (On: closed / Off: open) Product Size 45.0 x 30.7 x 11.5mm Package Size 147 x 90 x 40mm Product Weight 112.6g Gross Weight 137.8
