Industry Wireless I O Module Ethernet DI DO Wireless AI AO
Controller 1W Power Output
1. General Introduction
LS-HR RTU series is specially designed for wireless I/O control.
The user can choose different combinations of module 2AI, 2AO, 4DI
or 4DO inside to achieve your I/O control requirements . There are
3 types products according your different control distance (radio
based 1W, radio based 5W and 4G based no distance limit). It has 1
RS485 port (support Modbus RTU protocol) and 1 Ethernet port
(support Modbus TCP/IP protocol).
LS-HR RTU are widely used for wireless connection between Siemens
PLC, Schneider PLC, Rockwell PLC, Mitsubishi PLC, Omron PLC and
Delta PLC etc. LS-HR series DTU can also connect with VFD, HMI, PC
for wireless communication. It supports point to point, point to
multi-points wireless data transmission. They are widely used in
water management, oil field management, electric power control,
transportation monitoring, whether station, automatic building
management, alarm etc. Wireless solution help users collect and
transmit data in time. It is a reliable and competitive solution.
Without wiring cable, it reduce much time and cost.
2. Application Field
* Pressure, flow rate, temperature etc data collections, wireless
transmission and control in water/waste water treatment field
* Wind speed, rainfall, humidity etc data collection, wireless
transmission and control at whether monitoring station
* Temperature, humidity, concentrations of CO2 etc data collection,
wireless transmission and control in agriculture greenhouse
* AGV wireless monitoring and control
* Other kinds of OEM equipment wireless data collection and
transmission
* Wireless communication between PLC and sensors on Chemical
machinery and equipment, oil field.
