This SSR Unit is a DC to DC single phase solid state relay controller kit, that comes with a single phase solid state relay and ESP32C3 controller board. It supports key control, I2C slave, and Modbus networking modes of operation. There is an integrated programmable full-colour RGB LED for state indication, and clear to operate.

This kit is contactless and has semiconductor switching elements. It has several advantages such as high switching speed, extremely long life, low switching noise, no switching spark and more reliability than most mechanical relays. Widely used in digital program control devices, motor control devices, temperature control, data processing systems and computer peripheral interface devices.

Features

• Single-phase solid-state relay
• Three operating modes. – Push button control – I2C slave (support device I2C address configuration) – Modbus networking (supports device ID configuration)
• Programmable full-colour RGB LED
• RS485PWR interface (support input 9-24V to power the device)
