8-Channel Relay Module - 12V (High and Low Level Trigger) Previous 
The 4-Channel Relay Module is a 12V DC switching module with four independent channels. It is designed for relay-based control through low-voltage input signals and includes selectable HIGH or LOW trigger operation using a jumper. The module supports external circuit connection through screw terminal blocks and includes LED indicators for status display. It is built as a relay module for control applications that require multiple switching channels.
