5V 12V 4 Channel Relay Module With Optocoupler Sensor Low Level Trigger–OKY3013-5

Product Model: OKY3013-5

5V 12V 4 Channel Relay Module With Optocoupler Sensor Low Level Trigger

Product Description

1. the module complies with international safety standards, the control area and the load region isolation trench;
2. with the power supply and relay instructions, pull off, disconnect does not shine;
3. the signal input with signal common terminal will start with regular conduction;
4. can be used as a microcontroller development board module can be used as home appliance control;
5. the control DC or AC signal, you can control 220V AC load;
6. there is a normally open and one normally closed contact;
7. blue KF301 terminals to the control line is more convenient.

Product Description

Module interfaces:
Input section :
VCC: positive power supply ( by relay voltage supply )
GND: power supply is negative
IN1-4: relay module signal to trigger the end
The output section :
1. Normally open 1-4 : Relay normally open interfaces , relay before floating , pull back and Public shorted
2. Common side 1-4 : Relay Common Interface
3. Normally closed terminal 1-4: normally closed relay interface relay shorted before the public , after the pull- vacant
Trigger client’s request :
Signal as the trigger terminal phase with the other modules , to ground ( negative) between the two modules connected together only valid if sharing power , you can take a separate signal line on it.
High and low Trigger:
Refers to a high signal to trigger the trigger terminal (IN) between the negative electrode and a positive supply voltage , typically in a trigger terminal connected to the positive power supply with the trigger , the trigger end of the positive electrode when the voltage reaches the trigger or when voltage relay then pull .
Low voltage trigger refers to OV, or trigger voltage is lower than the voltage supply terminal of the positive and negative power supply terminal signal triggers between low enough to trigger voltage, so that relay , which is usually the a trigger and trigger negative terminal connected to the power supply , the relay will pull .
