Comtac Cluey KM NBM - NB-IoT/LTE-M Monitor & Controller

IP65, 8xDI + 4xDI

The Cluey is a smart controller designed for monitoring and control tasks in electricity, water or other infrastructure networks. Built in a robust housing with IP65 protection and designed to suit a wide range of use cases and applications. Based on a LoRaWAN design, this NB-IoT Controller is extremely power efficient, and is especially suitable for applications based on battery or alternative power sources.

Select a configuration that suits your application, wire the device accordingly and set your individual parameters. With the controller and monitoring intelligence already present in the Cluey, no need for complex programming.

Save battery by only transmitting when necessary; the Cluey uses clever signal processing allowing for threshold monitoring and other logical operations to support event driven and efficient radio transmission. This reduces uneccessary transmissions to a minimum for increased operational lifetime.

For added flexibility the Cluey can be either battery powered, with a lifetime of up to 10+ years, or powered by 24VDC. If Cluey is normally powered by mains, the battery is used for backup in the event of power failure.

NB-IoT / LTE-M support brings flexibility for applications, NB-IoT is best suited for reporting applications where power consumption if of highest priority. LTE-M will be more suitable if downlink and frequent report intervals is necessary.
