1 2 4 8 16 Channel DC 5V Relay Module with Optocoupler Low Level Trigger Expansion Board for arduino Raspberry Pi
1 Channel :
The new 5V Relay Module
Can be used as microcontroller development board module can be used as home appliance control
5 V-12V to TTL control signal
The control signal DC or AC, 220V AC load can be controlled.
There is a normally open and one normally closed contact
A power indicator light
A control indicator, pull off, disconnect does not shine
Transistor drive to increase the relay coil control pins high impedance.
The control pin has a pull-down circuit to prevent malfunction relay vacant
