Vutlan: VT825t

Monitoring device for data centers

The VT825t monitoring device measures key environmental and system parameters such as temperature, humidity, voltage, leaks, smoke, and airflow.
The device features analog, digital, CAN, Modbus, and relay interfaces for integrating sensors and expansion modules. It manages up to 130 physical sensors and up to 1000 elements, including virtual sensors, logic functions, triggers, timers, IP camera groups, and notifications. If needed, the device can be expanded with additional inputs and outputs as well as communication modules.
VT825t can trigger alarms via email, SNMP trap, SMS, Telegram, or audible alarms. SMS alarms are only possible in conjunction with the optional LTE slot modem. The integrated web interface allows you to configure sensors, visualize measured values, and manage system functions.
Additionally, the device features a USB port and a micro-SD slot for system upgrades, log recording, and backup.
VT825t is designed for use in server rooms, data centers, and technical infrastructures and is mounted in a 19" rack (1U). Power is supplied via 100–240 V AC; redundant power supplies are available as an option..
