3.3V 5V 12V 24V 8 Channel Relay Module High and Low Level Trigger with Optocoupler Output way for Arduino | Электронные

Module description:
1. The module adopts genuine high quality relay, the maximum load of normally open interface: AC 250V/10A, DC 30V/10A;
2. Using patch optocoupler isolation, strong driving ability, stable performance; trigger current 5mA;
3. Module working voltage is 3.3V 5V 12V 24V
4. Product size: 142*50*17 mm
5. The module can be triggered by a jumper to set a high level or a low level;
6. Fault-tolerant design, even if the control line is broken, the relay will not move;
7. Power indicator (green), relay status indicator (red)
8. The interface design is user-friendly, all interfaces can be directly connected through the terminal block, which is very convenient.
9. With 4 fixing bolt holes, hole 3.1mm
 
Module interface:
DC+: Connect to the positive pole of the power supply (voltage is required by relay)
DC-: connected to the negative pole of the power supply
IN: can control the relay to pull in high or low level
Relay output:
NO: The relay normally open interface, the relay is suspended before the suction, and the short is connected with COM after the suction.
COM: Relay common interface
NC: The relay normally closes the interface, and the relay is shorted to COM before the suction is closed.

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