4 CH 20A Relay Switch Module(With Current And Voltage Detection)
The 4 CH 20A Relay Switch Module (With Current And Voltage Detection) serves as a system switch execution unit, typically installed in a distribution box. It features built-in 4-channel current detection, 4-channel voltage detection, 4-channel power detection, and 4-channel energy consumption detection. The module is equipped with 4 intelligent relays, each capable of independently controlling the switching of lighting fixtures up to 4400W, and includes forced cut-off and interlock functions. It detects the actual current usage of each circuit and, by comparing real-time current with normal current, accurately identifies any damage to the circuit's lighting fixtures. Additionally, it is equipped with single-phase AC voltage detection functionality.
