12V 8-Channel Relay Module Optocoupler Low Level Triger for Arduino Precise

12V 8-Channel Relay Module Optocoupler Low Level Triger for Arduino Precise

Module Description:
1, the module complies with international safety standards, the load control area and regional isolation tank;
2, using double-sided FR-4 circuit board design, high-end chip production process;
3, using loose music authentic relay control;
4, with the relay instructions, pull off, disconnect does not shine;
5, the signal input has a low signal, often beginning with a common terminal will be turned on;
6, the relay can control the various devices and the load;
7, 8 and 8 normally open normally closed contact;
8, blue KF301 terminals to the control line is more convenient.
