pump on off control

433MHz Wireless Modbus RTU , Wireless Tank Level Monitor System 2km Remote Control Pump 2DO



This is a wireless pump control project.


On tank side, we use a wireless analog I/O module to collect the level sensor's 4-20mA signal


Control center, there is a pump nearby. We use a LS-RDIO0202. connect its I/O port with pump for pump ON-OFF control. Connects its RS485 port with HMI.Then you can monitor sensor level on HMI and remote control pump ON-OFF. Welcome to contact Sunny for more details.



Advantage of wireless solution

No wires to bury or maintain, no need to drill holes on wall

Reliable communication in all direction,any terrain, regardless of hills, walls, trees

Cost saving in installation and maintenance

Radio based, no need internet and monthly fee, full ownership of the system



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

- Support I/O reduction, field input, remote output

- Easy handing on RS485 network, support Modbus RTU protocol

- Support on-line upgrade. Can configure by customer in setting mode
