Model Number : 1 way relay moduleCondition : NewType : OtherBrand Name : SZYTF : Mainland China
1 way relay module 5V low level trigger relay expansion boardThis module 5V relay, low level triggerproduct description:1. The control area and the load area have isolation slots;2, with power and relay action instructions, the light is bright, disconnected and not lit;3. When there is a signal at the signal input end, the common end and the normally open end will be turned on;4, can be used as a microcontroller development board module, can be used as home appliance control;5. Control DC or AC signal to control 220V AC load;6, there is a normally open and a normally closed contact;7. The blue KF301 terminal is more convenient to connect to the control line.For the description of the high-level and low-level trigger modes, please do not understand the friends who do not understand:High-level triggering refers to the triggering mode of voltage between the signal input terminal and the ground, which can be understood as a way to trigger the short circuit of the signal input terminal and the VCC positive terminal;Low-level triggering refers to the triggering mode of the voltage between the signal input terminal and ground is OV, which can be understood as a way to trigger the short circuit between the signal input terminal and the GND negative terminal.
