The KET-MES-400 is a device equipped with a GSM/GPRS modem which, through the photodetector KET-IOI-100, counts the impulses related to the consumption of energy withdrawn and input to the electrical network, and can be configured through simple commands sent by SMS. The device is also able to send alarms via SMS and / or email in case of anomalies on inputs, power failure, exceeding temperature thresholds. It also ensures the recording of all variables on MicroSD and the sending of log files via email or ftp.
It is equipped with four digital inputs, two analog inputs and two relay outputs (optional).
