EWD95M LoRa DTU DIN

EWD95M LoRa DTU DIN RS485 ChirpIoT 5km

The EWD95M-400GL20(485) and EWD95M-900GL20P(485) are compact micro DIN-rail LoRa wireless data transmission modules (DTUs) from Ebyte. They utilize advanced ChirpIoT™ spread spectrum technology, offering excellent anti-interference performance and reliable long-distance communication. Both models support transparent data transmission, multiple operating modes, air wake-up, wireless configuration, automatic relay, communication key, AT commands, and IAP upgrade. They feature RS485 interface (with RS232 support), plastic housing with three-proof coating (anti-fungal, anti-humidity, anti-salt spray), and easy DIN-rail mounting.
