12 Channel Relay Module without light coupling 5v 12v 24v for Arduino

Description

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

2, using the industry’s top -quality ultra-compact two-way isolation optocouplers, anti-interference ability , stable performance ; trigger current is only 3mA;

3, the module voltage is 5V, 12V, 24V are available ; otherwise 1,2,4,8,12 road modules to choose from ;

4 user-selectable relay control level can be high pull, pull can also be low ; module containing limiting resistor can be used directly to control the power of positive and negative , can also use the MCU I / O port control ;

5 , fault-tolerant design , even if the control line is broken , the relay will not operate ;

6 , the power indicator ( red ) , 12 relay status indicator ( blue )

7 , interface design humane, all interfaces can be connected directly via terminal wiring leads , very convenient

8 , Module size : 12.0cm * 9.0m * 2.0cm ( L * W * H )

9 with 4 fixing bolt holes for easy installation
