Description
1 channel relay module product description
1. This module complies with international safety standards, and the control area and the load area have isolation slots;
2, using genuine relays;
3, with power and relay action instructions, the light is closed, the light is off;
4. When there is a signal at the signal input end, the common end and the normally open end will be turned on;
5, can be used as a microcontroller development board module, can be used as home appliance control;
6, control DC or AC signal, you can control 220V AC load;
7. There is a normally open and a normally closed contact;
8. The blue KF301 terminal is more convenient to connect to the control line.
For the description of the high-level and low-level trigger modes, please don't understand the friends:
The high level trigger refers to the trigger mode of the voltage between the signal input terminal and the ground, which can be understood as a way to trigger the short circuit of the signal input terminal and the VCC positive terminal;
Low-level triggering refers to the triggering mode of the voltage between the signal input terminal and ground is OV, which can be understood as a way to trigger the short circuit of the signal input terminal and the GND negative terminal.

16 channel relay product description
application:
1, 12V relay contact capacity 10A 250V, with optocoupler protection. The onboard power supply module does not require an external power supply. The I/O port drive is active low.
2, can be used as a microcontroller development board module, can be used as home appliance control, can also be used as PLC expansion output.
Module features:
1. Control signal voltage range: The trigger signal is low level 0-2V; the high level voltage cannot exceed 5V.
2, the use of quality isolation optocoupler, strong anti-interference ability, stable performance; trigger current only needs 3mA.
3, 1-16 road can be turned on/off at will, or any way.
4. Output form: Directly connect AC 220V 10A or DC30V 10A load.
5. The common terminal COM of each relay is independent, which is convenient for users to access different signals. Each relay has a normally closed and normally open port.
6. Each relay has an action indicator, which is illuminated and turned off.
7. The interface design is user-friendly, and all interfaces can be directly connected through the terminal block, which is very convenient.
8. There are 4 fixing bolt holes for easy installation.
9, PCB board size: 180MM (L) * 90MM (W) * 20MM (H).
Electrical parameters:
Supply voltage: 5V 12V (DC)
Supply current: greater than 200mA
Each relay can be loaded: 250V 10A (AC) or 30V 10A (DC)
Product instructions:
1. The power supply should meet the scope of use, DC 12V;
2. The power supply is required according to the wiring diagram and cannot be reversed;
3. The product uses LM2596S step-down chip with slight heat, which is a normal phenomenon. The relay has normal heating phenomenon for a long time, which is a normal phenomenon;
4. The load power should have a certain margin for the relay load. It should avoid high power (about 2000W) and work for a long time, which will have a certain impact on product life.
