Smart supervisor for rack Master wireless with LTE modem version

The KET-RKM-100 is a rack monitoring system designed to monitor all basic rack parameters.

The system allows monitoring of rack internal temperatures and PDU consumption.  It also has dedicated inputs for smoke, flood and door opening sensors.

Thanks to X-Monitor technology, each rack can be monitored by a slave unit connected to a single master unit via radio and/or RS485.

The master unit can be configured to send data to external platforms using internal LTE 4G, GPRS, Narrow Band modems or via Ethernet.

Equipped with dual 100-240 VAC power supply and supercapacitor to operate even in the absence of power for the time necessary to send the acoustic signal to the alarm.
Internal Flash memory 256 Kb, F-RAM and RTC for data protection.

It is also equipped with an infrared door opening sensor and temperature and relative humidity sensors to check the status of the device itself.
