Wireless Analog Output Module 4 Channels 4-20mA Signal Wireless Modbus RTU

I am pleased with them. It was a good choice for our small application. It is a robust device even it has a cheap price. I will use them in our further applications when we should use remote control. Thank you for your support.

—— Codreanu from Romania

Great news! We successfully performed the installation of the two units and transmitted our 4-20mA signal with both antennae. Even the smaller antenna suffices to transmit the signal without any losses whatsoever. So you can understand that we are very happy :) .

—— Kekarios from Greek

I believe you and your products. Sunny is very responsible. The RF modules are really strong and stable. Engineer's suggestions are useful to me. The most important is module's program can updrade on-line by myself. For some special projects, they can customize according my requirements. Thank you for your support all the time.

—— Singh from India

First of all I'd like to thank you for you're prompt service. The system now works perfectly. I left a positive response on your web site. I hope it attracts more customers for you.

Wireless Analog Output Module 4 Channels 4-20mA Signal Wireless Modbus RTU

 

 

General Introduction

LS-RAO04 Modbus RTU is a 4-ch wireless AO module, with 4 channels analog output, it is widely used to transmit sensor's 4-20mA or 0-5V analog signal. So your sensors can wireless connect with control center. We have types of different module to control different distance.

 

Wireless control 2km-3km by 1W RF

Wireless control 5km by Lora

Wireless control long distance, no limit by 4G module

Link your sensor with PLC/HMI wirelessly

Welcome to try!!!

 

Advantage of wireless solution

- No wires to bury or maintain, no need to drill holes on wall

- Reliable communication in all direction,any terrain, regardless of hills, walls, trees

- Cost saving in installation and maintenance

About value calculation

Analog input

Our analog module’s max measure range value is : 0X7FFF

1. Directly measure current and voltage

Exact value=value you read/0x7FFF*max range

For example: to read the 1st passage of module’s (with max range of 0-20mA) input value

Register 0x0008(analog input of the 1st passage)

Feedback: 0x3801

Current value: (0x3801/0x7FFF)*20mA=8.7509mA

 

2. To measure sensor’s value(4-20mA, 0-6 meter level sensor)

If feedback value is less than 6554, level value is 0

If feedback value is bigger than 6554, level value=(value read-6554)/(32767-6554)*measure ranges

For example: feedback value is 0X3801, then corresponding level value is: ((0X3801-6554)/26213)*6 meter=1.7815 meter

 

Analog output

Analog module’s max measure range is: 0x7FFF

Directly control output current and voltage

Write register value=current or voltage value/measure range*0x7FFF

For example: to control the 1st passage of analog module whose max measure range is 0-20mA

Register 0x0048 (analog output of the 1st passage)

To write register value:(8.75/20mA)*0X7FFF =14336=0x3800
