LC-101H and LC-102H are lighting control modules designed specifically for smart home applications, with the former being a single-loop and the latter a dual-loop model, both equipped with AC load current measurement capabilities. These modules not only effectively control lighting circuits but also provide real-time monitoring of load current, giving users an intuitive understanding of the lighting system's operational status.
 
Since the lighting circuits typically use inductive loads, switching can generate strong inrush currents (approximately 10 to 20 times the working current), which may damage the relays within the modules. The LC-101H and LC-102H are equipped with high-power relays that are resistant to inrush currents, allowing them to withstand these surges, prolonging their lifespan and reducing maintenance needs.
 
When users turn the lights on or off, the modules can detect the relay's switching state by measuring the load current, ensuring the normal operation of the lighting control system and promptly identifying any issues. Additionally, the relays in these modules utilize a Form C design, supporting dual-loop configurations with physical switches, providing users with greater flexibility and convenience. The current measurement feature also helps users monitor load current and check the relay's switching status, ensuring that the load operates correctly in the lighting circuit and preventing relay sticking.
 
The LC series lighting control modules are user-friendly, allowing for installation and operation without professional skills, and can control lighting channels without the need for software. When software control is required, programming can be done via the Modbus RTU communication protocol, and the Modbus RTU communication address can be set by hardware.
