Introduction
LS-RAI02 Modbus RTU is a 1W I/O module, 2 analog inputs, Wireless control 2km-3km. Use to connect sensors with PC/PLC wirelessly.
We can also instead the RF module inside by Lora module or by 4G module. So the distance can be longer.
Lensen Wireless RTU features
- Portable device, DIN-rail mounting for easy installation
- Isolated inputs
- LEDs for power supply, communication, input, output status
- Flexible networking, point to point or point to multipoints
- DIP to change different modes
- Different types of I/O, DI, DO, AI, AO are available
- I/O expandable
- Short delay time
- Easy handing on RS485 network, support Modbus RTU protocol
- Support on-line upgrade. Can configure by customer in setting mode
Character:
Transparent I/O System
Not need internet, no third party cell, no monthly fees

General introduction
LS-RAIO Modbus RTU is an industrial controller designed by Lensen Technology. It supports point to point, point to multi-points wireless AI, AO (4-20mA or 0-5V or 0-10V signal) collection and control. This wireless RTU has the advantage of easy installation, no program required, no communication fee. It is reliable and cost-effective substitution for rail signal cable and slip ring signal wire.
This series we have 2AI, 2AO, 4AI and 4AO 4 items. Power output we have 2 versions, one is 100mW for 600m LOS control distance, and another one is 1W for 3km LOS control distance. For longer control distance, we also have other higher power output radio modem to configure.
Application area
LS-RAIO series are widely used for sensor’s signal wireless collection and meters’ data wireless transmission, kinds of sensors data like liquid level, flow, pressure, weight, temperature, humidity, vibration, distance are applied. So wireless AI, AO modules are widely used in oil, chemical industry, metallurgy, water treatment, environmental protection, air conditioning, medicine and other fields.
