1, the module adopts genuine high-quality 30A relay, normally open interface maximum load: AC 250V/30A, DC 30V/30A;.

2, the use of chip optocoupler isolation, drive ability, stable performance; trigger current 5mA;

3、Module working voltage has 5V

4, the module can be set through the jumper high level or low level trigger

5, relay control terminal voltage and trigger terminal voltage energised jumper can be done before and after the level of complete isolation, can be done before and after the two levels of different voltage requirements (such as 24V for relay, trigger with 5V), need to contact customer service to change the parameters, the price is different;

6, fault-tolerant design, even if the control line is broken, the relay will not act;

7, power indicator (green), relay status indicator (red)

8, interface design humane, all interfaces can be directly connected through the terminal leads, very convenient

9, with 4 fixed bolt holes, hole 3.1mm, spacing 44.5mm * 27.5mm

Second, technical parameters:

Relay Version Static Current Maximum Current Trigger Current Trigger Voltage(Low) High

5V 5mA 190mA 2-4mA 0-1.5V 2.5-5V

12V 5mA 80mA 2-4mA 0-4V 4.5-12V

24V 5mA 50mA 2-4mA 0-8V 8.5-24V

Third, the module interface description:

1.DC+: DC power supply positive pole of the module (trigger terminal voltage positive pole)

2.DC-:DC power supply negative pole of the module (trigger terminal voltage negative pole)

3.IN: signal trigger (default trigger voltage and power supply is the same)

4.JD+: relay control terminal voltage positive pole

5.JD-: relay control terminal voltage negative pole

6. DC+ and JD+ are shorted with jumper caps, DC- and JD- are shorted with jumper caps, and the trigger terminal has the same voltage as the relay control terminal.

7. High and low level trigger mode selection, as shown in the figure, the jumper is connected to the L terminal, the IN terminal is low level trigger, and the H terminal is connected to the high level trigger.

8. Normally closed terminal (NC): the relay is normally closed.

9. Common terminal (COM): relay common terminal

10. Normally open terminal (NO): normally open terminal of relay
