16-channel 5V Relay Module with Optocoupler for Microcontroller

16-channel 5V Relay Module with Optocoupler for Microcontroller Description

1、Control signal voltage range: The trigger signal is low level 0-2V; the high level voltage cannot exceed 5V. 2、Adopting the industry's top quality isolated optocoupler, it has strong anti-interference ability and stable performance; the trigger current only needs 3mA. 3、1-16 channels can be turned on/off at will, or any way. 4、Output form: Directly connected to AC 10A or DC30V 10A load. 5、Each relay common terminal COM is independent, which is convenient for users to access different signals. Each relay has a normally closed and normally open port.
Features:
2. Adopting the industry's top quality isolated optocoupler, it has strong anti-interference ability and stable performance; the trigger current only needs 3mA.
3. 1-16 channels can be turned on/off at will, or any way.
5. Each relay common terminal COM is independent, which is convenient for users to access different signals. Each relay has a normally closed and normally open port.
6. Each relay has an action indicator, which is illuminated and turned off.
7. The interface design is user-friendly, and all interfaces can be directly connected through the terminal block, which is very convenient.
8. There are 4 fixing bolt holes for easy installation.
9. PCB board size: 180MM (L) * 90MM (W) * 20MM (H)
11. Can be used as a microcontroller development board module, can be used as home appliance control, can also be used as PLC expansion output.
Specification:
Condition: 100% Brand New
Item Type: Relay Module
Power Supply Current: More Than 200mA
Package List:
1 * Relay Module
Product Instructions:
1. The power supply should meet the scope of use, DC 5V;
2. The power supply is required according to the wiring diagram and cannot be reversed;
3. The product uses LM2596S step-down chip with slight heat, which is a normal phenomenon. The relay has normal heating phenomenon for a long time, which is a normal phenomenon;
4. The load power should have a certain margin for the relay load. Avoid high power (about 2000W) and work for a long time, which will have a certain impact on product life.
