The HT573 is a simple Single Relay Board which can be used with 5VDC microcontroller such as Arduino to switch other electrical devices on and off such as Solenoid Valve, Motor, Light, etc... When 5VDC signal was applied to the input of the boards, the relay coils will be energized to turn the devices on and off.
Input Voltage: 5VDC
NPN Type (Active High)
Compatible with any 5V microcontroller
Reverse polarity protection
LED Indicator for Relay On
Check off the components in the package against the component listing before assembly.
Start with the smallest components working up to the taller components, soldering any interconnection wires last.
Place and Solder the components into the board, make sure the components are in right position according to the overlay of PCB.
Test & Adjustment
After assembled, please check & ensure the value & polarity for all components were inserted into PCB correctly, wrong polarity connection of capacitors can caused explosion of failure.
Next, ensure all these leads are soldered, no solder bridges between adjacent pads and no dry joint.
Once confirmed, connect the power source to the circuit board.
When input signal (5V) is applied, the relay coil will be energized to enable the output. Also, the Red LED indicator on the PCB will turn on.
When input signal is removed, the relay coil will be de-energized to disable the output and the Red LED indicator will turn off.
Package includes schematic, printed circuit board and components
You need to have a soldering skill and basic knowledge of testing
