Touch Relay Module with Delay Timer 220V Previous 
The 4-Channel Relay Module - 12V is a switching module for controlling high-voltage and high-current circuits from low-voltage control devices. It operates at 12V DC and provides four independent channels for simultaneous control of separate circuits. Each channel uses a low-level trigger, activating when the input signal goes low. The module includes screw terminal blocks for external connections and LED indicators for channel status. It is designed for applications that require relay-based switching and remote control of electrical devices.
