Product Details
The A810-L433M37 is an industrial high-reliability wireless data radio specialized in ultra-long-distance communication with a maximum stable transmission distance of 25 km. It operates on the 410–441 MHz frequency band and delivers a high transmit power of 5W (37 dBm). By adopting advanced LoRa spread-spectrum modulation, the radio achieves outstanding far-reaching signal coverage as its core competitive advantage.
Dual industrial interfaces RS232 and RS485 are configured to connect various field automation terminals. Equipped with an embedded high-efficiency cyclic error correction algorithm, the module maintains high coding efficiency and powerful error correction performance, greatly strengthening anti-interference capacity and supporting continuous stable operation in complex outdoor long-distance application environments.
