433MHz 2km Remote I O Module Control RS485 Connect PLC 2AI Collect 4-20mA Analog Signal 2DO

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.

It is 1 master to many slaves application. Support Modbus RTU protocol.
 
Master is the PLC at RO plant. This side we recommend a LS-R324 to connect with PLC and RO Plant. LS-R324 is to collect all slave's data, forward to PLC for analysis. PLC process data, give command to RO Plant.
 
Slaves are the sensors on tank, the valves and the pumps.
 
a. About level sensors, there are 2 types, because there is salt water, to avoid Corrosion, we don't suggest thrown-in type sensor. Ultrasonic level sensor is more recommended.
Each sensor, you need an analog I/O module to collect and transmit the level sensor's 4-20mA signal to PLC. Use our LS-RAI02 module, it has 2 analog inputs.
 
b. About the pump, each one, you need a digital I/O module to start or close the pump. It is to control when we should intake water according tank level. Here we recommend LS-RDIO0202, it has 2 digital inputs and 2 relay outputs.
 
c. About the valves, each one, you need a digital I/O to start or close the valve. It is to control when we should blow off water according the tank level. Here we recommend LS-RDIO0202, it has 2 digital inputs and 2 relay outputs.
