Modulo per Arduino - 5V Relay Module
5V Relay Module
1. The new 5V Relay Module
2. Can be used as microcontroller development board module can be used as home appliance control
3. 5V-12V to TTL control signal
4. The control signal DC or AC, 220V AC load can be controlled.
5. There is a normally open and one normally closed contact
6. A power indicator light
7. A control indicator, pull off, disconnect does not shine
8. Transistor drive to increase the relay coil control pins high impedance.
9. The control pin has a pull-down circuit to prevent malfunction relay vacant.
