LoRaWAN Ex d Digital Input Node
SKU#
WSLRWEX-DI
WSLRWEX-DI is a LoRaWAN Node with Ex d explosion-proof approval and comes with 02 digital inputs for detecting the status of the pump, valve...or counting pulses from the flow meter, energy meter... Ultra-low-power design and smart firmware allow the device to run on a single battery type C for 5 years or more with 10 minutes update. It supports global frequency bands EU868, IN865, RU864, KR920, AS923, AS923-2, AU915, and US915. The sensor can work perfectly with any LoRaWAN Gateway on the market. Typical applications: detecting the status of the pump, valve...or counting pulses from the flow meter, energy meter...
