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
Projects Description:
1. Customer needs to minitor 10 tanks.
2. Intake or glow-off water by start/off the pumps or the valves.
3. Distance is within 1km.
4. Need wireless solution
