WSLRWEX-AO is a LoRaWAN device featuring an analog output of 4-20mA and certified with Ex d explosion-proof approval. It is designed to receive data from a LoRaWAN gateway and output the corresponding value to the 4-20mA port. In P2P-LoRa mode, it can also receive data directly from any P2P- LoRa sensor. This solution enables seamless wireless data transmission between legacy instruments with 4-20mA outputs and reading devices such as PLCs, RTUs, and DCS systems. It supports global frequency bands, including EU868, IN865, RU864, KR920, AS923, AS923-2, AU915, and US915.
