16 relay module with optocoupler protection and LM2576 power

One module description 

the module uses genuine quality relay , normally open interfaces Maximum load : AC 250V/10A, DC 30V/10A; 

usingThe industry’s top -quality isolation optocoupler, Anti-interference ability , stable performance ; trigger current is only 3mA;

the module Operating voltage 5V, 12V, choose from ; otherwise 1,2,4,8,12Lu modules to choose from ;

Low pull ;Modules with current limiting resistor ,You can directly use the power of positive and negative controlCan also beUseSCMOfI / O portsControl;

the power indicator ,16Relay status indicator

the interface design of human nature , all interfaces are available through a direct connection terminal leads , very convenient

with 4 fixing bolt holes for easy installation

1. 12V 16-Channel Relay interface board, and needs 3.3V/5V Driver Voltage.
