4-20mA Wireless I O Module 2 Channels AI 4-20mA Wireless Data Transfer 2-3km

4-20mA Wireless I O Module 2 Channels AI 4-20mA Wireless Data Transfer 2-3km

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

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.

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.
