What will I get?
Relay module, is in size of: 6 channel, 5V voltage, 10A AC250V/DC30V maximum load current and voltage, 0-4V trigger voltage, 3mA trigger current, 105mm x 53mm/4.13-inch x 2.09-inch(L*W)
In the package of: 1pcs x Relay module
Is there any advantages of the product?
Photo coupler isolation strong driving ability, stable performance; It can be connected directly through the terminal block, which is convenient for connection; Fixing screw hole position for easy installation
How to use it?
Module interface:
1. VCC: connected to the positive pole of 5V power supply
2. GND: connected to negative pole of 5V power supply
3. In1-In6: signal trigger terminal, active at low level
Relay output terminal:
1. NO1--NO6: normally open interface of relay, the relay is suspended before closing, and is short circuited with COM after closing
2. COM1--COM6: common interface of relay
3. NC1--NC6: normally closed interface of relay. The relay is short circuited with COM before closing and suspended after closing
What should I notice?
Please pay attention to selecting the appropriate relay module, especially the voltage and current
