4 Channel 5V DC Relay Module Solid State High Level SSR G3MB-202P 2A 240V

High-level trigger: In industrial control, called PNP trigger, positive trigger, that is, the relay closes when the trigger voltage reaches the trigger condition before the trigger terminal and the negative pole of the power supply. Stable performance of electronic components, so that your equipment can work stably. High sensitivity of this product. The use of the product expansion capability, can be used for all types of DIY. Equipped with to ensure the safe use of this module. 5V solid state relays 240V 2A, output with resistive fuse 240V 2A. Input power supply: 5V DC (160MA) Module interface: DC +: positive power supply (by relay voltage power supply) DC-: connect power negative CH: Relay Module signal triggering end (high level trigger effective) Note: Power must be DC voltage and need to be consistent with the voltage relay Package Included: 1 x 4 Channel 5V DC Relay Module Solid State High Level SSR G3MB-202P 2A 110-240V
