  • Single-phase DC SSR Unit (CDG1. 1DD-10A)
  • Features high-speed, contactless semiconductor switching
  • Engineered for corrosion resistance and humidity tolerance
  • Supports key control, I2C slave, and Modbus networking modes
  • Includes programmable full-color RGB LED for clear indication
  • Designed for frequent switching in harsh environments

The Single-phase DC SSR Unit (CDG1. 1DD-10A) is a DC to DC single-phase solid state relay controller kit, which includes a single-phase solid state relay and an ESP32C3 controller board. This unit supports key control, I2C slave, and Modbus networking modes of operation. It also features an integrated programmable full-color RGB LED for clear state indication.

The unit is contactless and utilizes semiconductor switching elements. This design provides several benefits including high switching speed, exceptional longevity, minimal switching noise, and the absence of switching spark, making it more reliable than many mechanical relays. It is commonly used in digital program control devices, motor control devices, temperature control systems, data processing systems, and computer peripheral interface devices. The unit is specifically engineered for harsh environments that require corrosion resistance, humidity tolerance, explosion-proofing, and frequent switching.
