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.
9 , Module size : 138m * 56mm * 18.5mm ( L * W * H ) , Weight : 120g
10 with 4 fixing bolt holes, hole 3.1mm, pitch 131mm * 49.5mm
11, finished by 100% functional testing and stability testing
Two module interface :
