 Module Description:

1. The module uses relays with large open contacts for high-load AC applications.250V/10ADC30V/10A";
2. Adopts SMD photocoupler isolation, with strong driving capability and stable performance.触发电流5mA；
3. Module operating voltage5V、12V、24VAvailable for selection.
4. The module can be set to trigger with high or low logic levels using jumpers.
5. Fault-tolerant design, even if the control line is broken, the relay will not operate;
6. Power indicator (green), relay status indicator (red)
7. The interface design is humanized, and all interfaces can be directly connected through terminal strips, which is very convenient.
8. Module Size:50mm * 26mm * 18.5mmLength * Width * Height
9. There are four fixed bolt holes, with a diameter of 3.1mm, and the spacing is 44.5mm * 20.5mm.
Module Interface:
1、DC+：Connect to the positive power supplyThe voltage can be selected according to the requirements of the relay, with options of 5V, 12V, and 24V.
2、DC-：Connect to the negative power supply
3. IN: The relay can be controlled to make or break by high or low level.
Relay Output Terminal:
1. NO: Relay normally open interface, before the relay engages, it is floating, and after engagement, it is short-circuited to COM.
2、COM：Relay Common Interface
3. NC: Relay normally closed interface, short-circuited to COM before the relay engages, and floated after engagement.

High-low level trigger selection terminal:

1. When the jumper is short-circuited to LOW, it triggers at low voltage.

2. When the jumper is shorted to high, it is a high-level trigger.

 A module description:

1, the module uses genuine high-quality relays, the maximum load of the normally open interface: AC 250V/10A, DC 30V/10A;
2, using patch optocoupler isolation, strong driving ability, stable performance; trigger current 5mA;
3, the module working voltage is available in 5V, 12V, 24V;
4. The module can be triggered by a jumper to set a high level or a low level;
5, fault-tolerant design, even if the control line is broken, the relay will not move;
6, power indicator (green), relay status indicator (red)
7, the interface design is user-friendly, all interfaces can be directly connected through the terminal block, very convenient
8, module size: 50mm * 26mm * 18.5mm (length * width * height)
9, with 4 fixing bolt holes, hole 3.1mm, spacing 44.5mm*20.5mm
Two module interface:
1. DC+: Connect the positive pole of the power supply (the voltage is selected according to the relay, and there are 5V, 12V and 24V options)
2, DC-: connected to the negative pole of the power supply
3, IN: 可以控制继电器拉高或拉低
Relay output:
1. NO: The relay normally open interface, the relay is suspended before the suction, and the short is connected with COM after the suction.
2, COM: relay common interface
3. 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. 当跳线短接到LOW时，它由低电平触发;

2. When the jumper is shorted to high, it is triggered by a high level.

Third, technical parameters:
