Unit ACSSR

SKU:U139

Description

Unit ACSSR is a DC to AC single phase solid state relaycontroller kit, comes with a single phase solid state relay + ESP32C3 controller board. Supportskey control, I2C slave, and Modbus networking` modes of operation. Integrated programmable full-color RGB LED for for state indication, clear to operate.

This kit is contactless and adopts semiconductor switching elements. It has several advantages such as high switching speed, extremely long life, low switching noise, no switching spark and ultra-reliable than most mechanical relays. Widely used in digital program control devices, motor control devices, temperature control, data processing systems and computer peripheral interface devices. It is specially designed for harsh environments with corrosion, humidity or explosion-proof requirements and frequent turn-on/off requirements.
