Unit DCSSR

SKU:U140

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 widely used in digital program-controlled devices, motor control devices, temperature control devices, data processing systems, and computer terminal interface circuits, especially suitable for special occasions with frequent actions, explosion-proof, moisture-proof, and corrosion-resistant requirements.
