5V Relay Module, 16-Channel Relay Module Control Board with Optocoupler for Microcontroller, PC Board, Easily Control Household Appliances

1. Control signal voltage range: The trigger signal is low level 0-2V; the high level voltage cannot exceed 5V. 2. Adopting a high-quality, industry-leading isolated optocoupler, it has strong anti-interference capability and stable performance; the trigger current requires only 3mA. 3. 1 to 16 channels can be turned on/off at will or in any other way. 4. Output form: Directly connected to an AC 220V 10A or DC 30V 10A load. 5. Each COM relay terminal is independent, allowing users easy access to different signals. Each relay has a normally closed and normally open port. Specifications: Features: 1. Control signal voltage range: The trigger signal is low level 0-2V; 1. The high-level voltage cannot exceed 5V. 2. Adopting a high-quality, industry-leading isolated optocoupler, it boasts strong anti-interference capabilities and stable performance; the triggering current requires only 3mA. 3. 1 to 16 channels can be switched on/off at will or in any other way. 4. Output form: directly connected to an AC 220V 10A or DC 30V 10A load. 5. Each relay's COM terminal is independent, allowing users easy access to different signals. Each relay has a normally closed and normally open port. 6. Each relay has an active indicator that shows whether it is on or off. 7. The interface design is user-friendly, and all interfaces can be directly connected via the terminal block, which is very convenient. 8. There are 4 mounting bolt holes for easy installation. 9. PCB board size: 180 mm (L) * 90 mm (W) * 20 mm (H) 10. 5V relay, 10A capacity, 250V with optocoupler protection. The onboard power supply module does not require an external power supply. The I/O port reader is active at a low level. 11. Can be used as a microcontroller development board module, for household appliance control, or as a PLC expansion output. Supply voltage: DC 5V Supply current: over 200mA Load per relay: 250V 10A (AC) or 30V 10A (DC) Package list: 1 * Relay module Product instructions: 1. The power supply must meet the operating range, DC 5V; 2. The power supply must be connected according to the wiring diagram and cannot be reversed; 3. The product uses an LM2596S step-down chip, which may generate slight heat; this is normal. The relay will also heat up during extended use, which is also normal. 4. The load power should have a certain margin to accommodate the relay's load. Avoid high power (approximately 2000W) and prolonged operation, as this will impact the product's lifespan.
