Cost-effective measurement solution
- Low cost of deployment, no wires, no trenching, no conduit, etc…
- Low cost of operations with limited maintenance
Easiest to install and use
- Fully integrated power, communications and instrumentation
- Easy to mount on any structure, quick configuration
No need internet and monthly fee
1. Replacing the serial cable (radio modem, data module, wireless DTU) Power output: 100mW to 25W Distance: 0-20km RS232, RS485, TTL or USB interface modules
2. Voice transmission (Audio Modem) To transmit voice like talkie talkie, can also transmit data.
3. Wireless ON-OFF control (digital I/O module, wireless RTU) local I/O signal---------------------Field O/I signal local serial signal------------------Field I/O signal(support Modbus RTU)
4. Collect 0-5V, 4-20mA data (analog I/O module, Wireless analog acquistion) local analog I/O signal------------Field analog O/I signal local serial signal-------------------Field I/O signal (support Mosbus RTU)
