Beskrivning & information

16-channel 5V Relay Module Control Board with Optocoupler Protection for Microcontroller Module Beskrivning

Features: 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 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: 180MM (L) * 90MM (W) * 20MM (H) 10. 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. 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 Supply Voltage: DC 5V Power Supply Current: More Than 200mA Load Per Relay: 250V 10A (AC) or 30V 10A (DC) 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.
