Power Module

It is an 8 Channel Isolated 5V 10A Relay Module opto coupler, which can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, PLC, etc. It is also able to control various appliances and other types of equipment with a large current. Relay output maximum contact is AC250V 10A and DC30V 10A.

One can connect a microcontroller with standard interface directly to it. Red working status indicator lights are conducive to the safe use. The 8 Channel Isolated 5V 10A Relay Module optocoupler has a wide range of applications such as all MCU control, industrial sector, PLC control, smart home control.

So, ready to get switching on your Raspberry Pi?! This neat relay module features 8 x 12V relays rated at 10A/250V each. It is designed to switch up to 4 high currents (10A) or high voltage (250V) loads with the help of microcontroller!

Each relay can individually switch to on/off state. It only requires a voltage of approx 1.0V to switch the inputs on but can handle input voltages up to 12V. This makes it ideal for 3.3V, 5V & 12V devices.

1. High-level trigger refers to the signal voltage between input and trigger, can be understood as a signal input with VCC cathode short-circuit triggered away;
2. Low-level trigger refers to the signal voltage between the input terminal and Earth OV trigger, can be understood as the signal input terminal and the GND negative electrode short circuit triggered away  1-channel relay module connection.

1. Power supply and relay instructions, lit, the disconnect is off;
2. The input signal, signal, common Terminal and start conducting;
3. Useful for appliance control;
4. DC or AC signal, control, you can control the 220V AC load.
5. One normally closed contact and one normally open contact
6. Triode drive, increasing relay coil
7. High impedance controller pin
8. Pull-down circuit for the avoidance of malfunction
9. Power supply indicator and Control indicator lamp
10. The module is compliant with international safety standards, control and load areas isolation trenches.

The XL4015 5A DC-DC Step Down Adjustable Power Supply Buck Module is a 180 KHz fixed frequency PWM buck (step-down) DC/DC module, capable of driving a 5A load with high efficiency, low ripple, and excellent line and load regulation.

This product is a 180 kHz fixed frequency PWM buck (step-down) DC/DC module, capable of driving a 5A load with high efficiency,  low ripple, and excellent line and load regulation. 

The DC/DC buck module has applications where the input voltage is higher than the output voltage, such as battery, power transformer, DIY adjustable regulated power supply, LCD Monitor and LCD TV portable instrument power supply telecom/networking equipment, 24V vehicle notebook power supply, industrial equipment buck.

This module has an adjustable output Voltage. Also works as a dedicated charger for Lithium Batteries (Li-Ion, LiPo) as it is capable of controlling voltage. Ex. 12V buck to 3.3V, 12V buck to 5V, 24V buck to 5V,24V buck to 12V, 36V buck to 24V, etc.
