Fulabs 1 Channel 5V DC Solid State Relay Module Board Low Level Solid State Relay Module 250V 2A

Low-Level Trigger Principle

      When the voltage between the signal trigger terminal and the negative pole of the power supply is 0V, or the trigger terminal voltage is lower than the positive pole voltage to the trigger threshold, the relay is activated. This triggering mode is typically achieved by connecting the negative pole of the power supply to the trigger terminal.
