***** รับประกันสินค้า 30 วัน *****

Description:
1. using genuine quality relay module, normally open interfaces Maximum load: AC 250V / 10A, DC 30V / 10A;
2. using SMD opto-isolation, driving ability, stable performance; trigger current of 5mA;
3. The working voltage of the module is 5V, 12V, 24V
4. The module can be set to high level or low level trigger by jumper;
5. Fault-tolerant design, even if the control line is broken, the relay will not act;
6. Power indicator (green), relay status indicator (red)
7. The interface design is user-friendly, all interfaces can be directly led out through the wiring terminal, which is very convenient.
8. There are 4 fixing bolt holes, the hole is 3.1mm

Two module interfaces:
1. DC +: connected to the positive pole of the power supply (voltage according to the requirements of the relay)
2. DC-: connected to the negative pole of the power supply
3. IN: can control the output of the relay from high or low level :
3.1 NO: the relay is normally open Interface, the relay is suspended before pull-in, short-circuited with COM after pull-in
3.2 COM: relay common interface
3.3 NC: relay normally closed interface, the relay is short-connected with COM before pull-in, suspended after pull-in

High and low level trigger selection terminal:
1. When the jumper is connected to LOW, it is low level trigger;
2. When the jumper is shorted to high, it is triggered at high level
