1.this module meet safety standard, control areas and load area have the isolation groove;
2.optical coupling isolation module, triggering more reliable, more stable;
3.the double FR - 4 circuit board design, high-end SMT process;
4.have power and relay operation instructions, and bright, disconnect the dawn;
5.signal input with a high level signal, the common and often start conduction;
6.relay can directly control all kinds of equipment and load;
7.one often opened a normally closed contact;
8.blue KF301 terminal line more convenient.
9.module size: 53 x18x18. 5 mm;Net weight: 16 g
Module interface:
The positive (according to the relay voltage VCC: connect power supply)
GND: connect power negative
IN: relay module (effective) high level trigger signal trigger end
low level meaning:
Low level trigger refers to using the negative voltage at the GND connection way of a trigger and trigger the end, when the trigger side has 0 v low voltage or voltage to can trigger, the relay is off.
