Description: 5v 2 Channel Relay Module
The relay module is an electrically operated switch that allows you to turn on or off a circuit using voltage and/or current much higher than a microcontroller could handle. There is no connection between the low voltage circuit operated by the microcontroller and the high power circuit. The relay protects each circuit from each other.
Each channel in the module has three connections named NC, COM, and NO. Depending on the input signal trigger mode, the jumper cap can be placed at high level effective mode which ‘closes’ the normally open (NO) switch at high-level input and at low-level effective mode which operates the same but at low-level input.
Imported high quality double sided compact PCB.
Opto-Isolated inputs means your digital electronics is safe and noise free.
This relay module is 5V active low.
It is an 2-channel relay interface board, which can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, PLC, etc.
It is also able to control various appliances and other equipment with large current.
Relay output maximum contact is AC250V 10A and DC30V 10A.
Standard interface can be directly connected with microcontrollers.
Red working status indicator lights are conducive to the safe use.
Widely used for all MCU control, industrial sector, PLC control, smart home control.
