LoRa Wireless Analog Bridge
WW-3C28-AA (Synchronization Mode)
The WW-3C28-AA retains all the key features of the original WW-3C28 while adding a master-slave synchronization functionality for seamless wireless analog transmission. The addition of Analog In / Analog Out capabilities makes it ideal for applications that require precise, real-time analog signal transmission over long distances.
This version highlights the Analog In/Out as a primary feature while maintaining the original focus on synchronization and wireless transmission.
WW-3C28-AA is an enhanced version of the WW-3C28 outdoor wireless gateway, offering all the powerful features of its predecessor, with the added benefit of a synchronization mode. This new model is specifically designed to meet the demands of applications requiring wireless transmission of analog signals across long distances using LoRa technology. The WW-3C28-AA retains all the key features of the original WW-3C28 while adding a master-slave synchronization functionality for seamless wireless analog transmission.
In the synchronization mode, one unit operates as the master and the other as the slave. Analog signals are connected to the slave, transmitted wirelessly, and reproduced as analog output at the master side. This feature addresses customer requirements for wireless transmission of analog signal sources, making it ideal for industrial applications requiring reliable, low-power, long-range communication.
- Synchronization Mode: Allows wireless transmission of analog signals from the slave unit to the master unit.
- LoRa to RS-485 Gateway: Suitable for long-range, low-data, and non-immediateness communication in outdoor environments.
- Remote Power Saving Control: Allows for energy-efficient operation in remote environments.
- Rugged Design: IP68 waterproof rating and flame retardant materials ensure reliability in harsh environments.
