1. 5V relay contact capacity 10A 250V with optocoupler protection. The onboard power supply module does not require an external power supply. The I/O port drive is active low.
2. Can be used as a microcontroller development board, can be used as home appliance control, can also be used as PLC expansion output.
Instructions:
1. The power supply should meet the scope of use, DC 5V.
2. The power supply 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.
Features:
1. Control signal voltage range: The trigger signal is low level 0-2V.
2. Adopting high 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 220V 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.
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: 180 x 90 x 20mm (L x W x H)
Electrical parameters:
Supply voltage: 5V (DC)
Supply current: Greater than 200mA
Each relay can be loaded: 250V 10A (AC) or 30V 10A (DC)
