Unit ACSSR

SKU:U139

Description

Unit ACSSR is a "DC-controlled AC" single-phase solid-state relay controller kit, which includes a single-phase solid-state relay and an ESP32C3 core control board. It supports three operating 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 assembled and solidified using semiconductor components, making it a contactless switch. It has a series of advantages such as fast switching speed, high operating frequency, long service life, low noise, reliable operation, and no sparks.

This product is widely used in digital control devices, motor control devices, temperature control devices, data processing systems, and computer terminal interface circuits. It is especially suitable for applications that require frequent operation, explosion-proof, moisture-proof, and corrosion-resistant environments.
