2 Channels Wireless I O Module 0-5V Analog Input / Output 433MHz RS485 Interface

2 channels Wireless Analog Module 0-5V Analog Input and Output 433MHz

Introduction

This system includes a LS-RAI02 2ch analog input module and a LS-RAO02.2ch analog output module

It is ok to transmit 0-5V or 4-20mA or 0-10V analog signal

The control distance covers 2km LOS

One side analog input, one side analog output

LS-RAI02 Parameter

LS-RAO02 parameter

Application:

Wireless pump controls

Automate your tank level without running wire between the well pump and the tank. Wireless pump controls save you time and money.

Wireless tank level monitoring
simple wireless monitoring of your tank level from a remote location and receive critical status updates.

Smart agriculture

Pivot irrigation, soil pressure and temperature monitoring

Data Logging
Wirelessly acquire and log various data from a remote location using our analog I/O module

Stacker Control
Start and stop your stacker/reclaimir. Connect PLC in control center with stacker and reclaimer.

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 1^st 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

Shenzhen Qianhai Lensen Technology Co., Ltd mainly designs and produces industrial wireless data communication products including RF module, radio modem, DI, DO, AI, AO module and kinds of RF based remote control, telemetry systems and IOT products.

Our products are widely used in oil, gas, water, power industry, wireless alarm and security systems, intelligent traffics and irrigation, industry automation and many other M2M applications. RF data modules just instead the RS232, RS485 cable between different equipments to transmit serial data. RDIO series are designed for industry ON-OFF control. They are widely used for pump, valve, tank, motor, light, alarm control. RAIO series are used to collect voltage (0-5V) or current (4-20mA) signal. They are widely used to collect kinds of sensors data and signal. The GPRS RTU is suitable for transferring data from device to internet, and transferring data from internet (Monitoring center or server) to device.

Lensen commits to provide our customers better products and service. Our engineers are experts with more than 10 years experience in this field, rising to the challenge of developing high tech and competitive products. Apart from providing a series of off-to-shelf products, Lensen has the capability to cooperate with companies and individuals that need customized products and ODM wireless solution. Choose Lensen, your wireless systems will link faster.
