1. This product is an industrial-grade 8-channel relay module controlled by RS485 interface, featuring 8-channel switch input, adopting Modbus RTU protocol, and equipped with built-in power isolation, magnetic coupling isolation, and TVS protection circuits. It is designed with an ABS housing. This product is easy to operate and features fast communication speed, stability, reliability, and safety. It is suitable for various industrial control devices or applications with high communication requirements.
2. It supports setting the device address (1 to 255) to cascade multiple devices through the RS485 bus.
3. It has flashing on and off functions, allowing parameters to be set in the instructions to operate the relay to turn on for a certain period and then automatically turn off.
4. It has an integrated power isolation circuit on the board, providing stable isolated voltage, and the isolation end does not require additional power supply.
5. It has an integrated magnetic coupling isolation circuit on the board, capable of signal isolation, with high reliability, strong anti-interference, and low power consumption.
6. It has a self-resetting fuse and TVS (transient voltage suppressor) on the board, effectively suppressing surge voltage and transient peak voltage in the circuit, preventing overcurrent and overvoltage, and protecting against lightning and static electricity.
7. It has an integrated optocoupler isolation circuit on the board to prevent interference from the relays high-voltage circuit.
8. It uses a dedicated relay driver chip with built-in freewheeling diode protection, providing stronger and more stable driving capability.
9. The switch input has bidirectional optocoupler isolation, supporting both passive and active switch input, with an internal anti-bounce algorithm. The relay supports switch input linkage mode or flip mode control.
10. It has an anti-reverse connection circuit on the board to prevent damage to the circuit from reversed positive and negative connections.
11. It uses high-quality relays, allowing a load of up to 10A 250V AC or 10A 30V DC.
12. It has a rail-mounted ABS protective housing, making installation and use convenient, and is safer with the housing.
13. It has an external LED indicator light for easily checking the MCU status and signal transmission and reception status.

Unlocked! 🙏🏼
Format: Paperback
I did not know what to expect with this book; though Ive spent years studying Eastern spiritual traditions and have been incorporating them into my life with more vigor and earnestness in recent times.
Masuda Mohamadi is one of those not so frequent surprises; her writing and genuine enthusiasm for the topic of chakras is of the kind that can actively, in real time, spark a new course of action in the reader.
The book is truly inspiring and also full of illustrations and pictures that are helpful in grasping concepts and poses.
Needless to say, I highly recommend!
🙏🏼

Your one-stop shop for chakra awareness - perfectly concise and at the same time, expansive.
Format: Paperback
The author has an incredible talent and magically manages to put into words (and pictures) the key elements of our chakra system, why they matter, the force of good they can create, and more. She invites us into a practice and bank of knowledge she's an expert in, and facilitates our own discovery at a next level, no matter where we're starting from. Highly recommend this as your key source for knowledge in this area. SO useful and user-friendly!

A very good book that could use some corrective editing.
Format: Paperback, Format: Paperback
I like the book because it’s clearly written and easy to follow. The photos are clear and purposeful. Most of the info is very on-point.
I can’t give the book 5 stars because of one glaring annoyance. The author refers to the Sanskrit names of the chakras, which I really appreciate. She also names most of the yoga asanas (poses/postures) by the English translation of the original Sanskrit names. For some reason, she refers to Downward Facing Dog (Sanskrit: Adho Mukha Svanasana) as “Triangle Pose”. Triangle Pose (Sanskrit: Trikonasana) is actually a completely different asana. I don’t get why she would teach such a well known asana by an incorrect name.
I wouldn’t discourage people from the book over that. I think there is still a lot of good info to be read.

Powerful Tool for Personal Development
Format: Paperback
Masuda Mohamadi’s “Unlock the Power of Your Chakras” provides a clear and accessible overview of the chakra system that communicates esoteric ideas in a simple and practical manner. I love the layout of this book. It is designed for readers who want to understand what chakras are, but it's also very useful to anyone who is already familiar and wants to deepen their practice. It includes exercises to facilitate a deeper awareness of the energy of the chakras in one’s body. This framework allows the reader to engage with chakras in a powerful and personalized manner to address areas of imbalance in the body and build a practice toward manifesting improvements in one’s life.
In addition to this deep dive into each of the chakras, chapters explore practices, warm-ups, and beautiful meditations that ground yoga philosophy into daily life and ritual. I highly recommend this book as a tool for personal growth, to help teachers and students develop a practice using the chakra system, and for anyone looking for an opportunity to connect to what they are feeling in their body and mind and express it through yoga practice, meditations, and journaling.

A brilliant reference
Format: Paperback
If you are like me, and interested in this field, then I recommend you also get the The Energy Medicine Kit, which has a DVD where she demonstrates various energy routines, and an easy to follow five minute daily routine. This is now part of my daily routine. Everyone should have a daily routine for moving energy.
The book and the kit are stand alone products. I highly recommend both to everyone. I got the energy medicine kit first, and I am glad I did because there is nothing quite like seeing the exercises demonstrated, and I know I would not be doing these techniques properly if I did not first see them shown. The mutimedia is format is easier to follow and use.
The book also contains the five minute routine, and is more encyclopedic. If you are not already an advanced healer I recommend getting the kit first, because you are more likely to be able to follow a visual demonstration correctly. You are also less likely to understand the concept of energy testing without a visual demonstration which is like watching a magic show.
There is so much content in this book, which is based on the twin concepts of touch for healing and kinesiology (energy testing) in which she tests your muscle resistance,and then treats. Donna can see energy, but you can achieve the same thing with energy testing.
In this book, you learn about opening the chakras, and celtic weave, figure eights, strange flows, the aura, eye movement exercises, neurovasculars or fight or flight response and many other things.
If you have health challenges, you owe it to yourself to do everything you can to resolve them. Seek professional help, go see an energy healer to resolve the issues, and by all means use the techniques in this book, and the energy kit.
If you are like me you will be very pleased with this product. If you are unsure about which one to buy first, get the energy medicine kit. I wonder if this review was helpful.
