LoRa RF Industrial Transceiver
Wireless Transceiver (T-WT-300) is a compact industrial‐grade communication gateway intended to send process data in locations where installing cabling is difficult. It employs LoRa modulation within the 850-930 MHz ISM band to link up to 30 remote nodes. The device provides a line‐of‐sight range of up to 4 km and sends data to SCADA or monitoring platforms via Modbus TCP/IP over Gigabit Ethernet.
Key Features
Everything you need to connect remote sites, panels, and field devices to a single monitoring point without installing new cables.
Long-Range LoRa RF Communication
A 22 dBm transmit power and -118 dBm receiver sensitivity give the T-WT-300 a working range of up to 4 km line-of-sight, so it can reach field devices that sit well beyond the range of standard short-range RF modules.
Star or Mesh Network Topology
One gateway supports as many as 30 wireless nodes. These are set up in a star or mesh network based on the site layout, the terrain, and the way nodes must relay data to one another
Modbus TCP/IP Over Gigabit Ethernet
The onboard 10/100/1000 Mbps Ethernet port uses Modbus TCP/IP. This allows the T-WT-300 to connect to existing SCADA, PLC, and industrial automation systems without using protocol conversion.
Integrated Data Logger
Every unit includes a built-in data logger. It has 64 GB of internal storage which can be expanded to 256 GB. The standard logging period is one year, though this can be extended upon request. You can retrieve data using TCP/IP or USB.
IP65 / IK07 Rugged Enclosure
The enclosure is rated IP65 for protection against dust and water and IK07 for resistance to mechanical impact. It is designed for use in outdoor cabinets, on rooftops, and at unmanned sites. The operating temperature range is 0°C to +70°C.
Universal 90-260V AC/DC Power Input
A wide-range power input accepts 90-260V AC or DC with a maximum power draw of 30 W. This allows the same unit to operate under various site power conditions without requiring an external converter.
Applications
Wherever a wired connection is impractical or too costly to run, the T-WT-300 keeps remote points on the network.
