Relay control card with indicator light, 24V relay output

application:1. Relay contact capacity 24 V 10 A 250 V, with optocoupler protection. The integrated power module does not require an external power supply. I/O port drivers are active at a low level.2. It can be used as a single-chip development board module, used for home appliance control or as a PLC expansion output.Module Features:1. Control signal voltage range: low level trigger signal 0-2V; high level voltage cannot exceed 5V. 2. Using high-quality isolation optocoupler, it has strong anti-interference ability and stable performance; the trigger current only needs 3mA.4. Output form: directly connected to an AC 220V 10A or DC30V 10A load. 5. The public COM terminal of each relay is independent, allowing users to access different signals. Each relay has normally closed and normally open ports.6. Each relay has an action indicator light that turns on when connected and turns off when disconnected.7. The interface design is user-friendly, and all interfaces can be directly connected via terminal blocks, which is very convenient.8. There are 4 mounting bolt holes for easy installation.9. PCB Size: 180mm (length) * 90mm (width) * 20mm (height).Electrical parameters:Supply voltage : 5V 24V (DC).Supply current: greater than 200 mA Each relay can load: 250 V 10 A (AC) or 30 V 10 A (DC).Product Description:1. The power supply should meet the usage range, DC 24V; 2. The power supply conforms to the wiring diagram and cannot be connected backwards; 3. The product uses LM2596S step-down chip. It will generate slight heat, which is normal. The relay will also generate heat after working for a long time, which is normal.4. The charging power should leave a certain margin for charging the relay, and high power environments (about 2000W) and long-term work should be avoided, which will have a certain impact on the life of the product.
