Description Unit ACSSR is a single-phase AC solid-state relay control kit, containing a single-phase solid-state relay and an ESP32C3 core control board. It supports three working modes: Button Control, I2C Slave, and Modbus Networking, and integrates a programmable full-color RGB LED for various status indications. Compared with traditional mechanical relays, solid-state relays are made of semiconductor devices, designed with no contacts, and have advantages such as fast switching speed, high frequency, long life, low noise, reliable operation, and no arc spark. This product is suitable for applications such as industrial automation, motor control, and temperature control systems. Features Single-phase solid-state relay Supports load supply voltage: AC 24 ~ 480V Three working modes: Button Control I2C Mode (supports I2C address configuration) Modbus Mode (supports device ID configuration) Programmable full-color RGB LED RS485PWR control interface For Modbus control Supports DC 9 ~ 24V power input Communication rate configuration: 115200bps 8N1 Default ID: 0x0004 HY2.0-4P Grove control interface For I2C communication control Supports DC 5V power input 3.3V logic level communication Includes 1 x Unit ACSSR 1 x Single-phase solid-state relay 2 x 3.96-4P terminal blocks 1 x HY2.0-4P Grove Cable (20cm) 1 x Communication protocol manual Applications AC circuit switching 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 AC 24 ~ 480V 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 Weight 112.6g Gross Weight 137.8g Product Size 80 x 45 x 31mm Package Size 147 x 90 x 40mm Learn and Documents → DOCUMENTS
