Vutlan: VT855t

Monitoring Device for Data Centers

The monitoring device VT885t records key environmental and system parameters such as temperature, humidity, voltage, leaks, smoke, dust, vibration, access signals, motion and airflow.
It features analog and digital inputs, relay outputs, CAN bus and Modbus interfaces for the integration of physical sensors and optional expansion modules. The device can be expanded with additional communication interfaces if required.
VT855t manages up to 150 physical sensors and up to 1000 elements, including virtual sensors, logic functions, triggers, timers, IP camera groups, and notifications. Alarms can be triggered via email, SNMP trap, SMS, Telegram or audible signal devices, with SMS alarms available only when using the optional LTE modem.
The integrated web interface allows configuration of sensors, visualization of measurement data and centralized management of system functions. A USB port and MicroSD slot are available for system upgrades, log recording and backup.
The device is designed for 19-inch rack mounting. Power is supplied via a 230 V AC mains connection. Optional variants with redundant power supply or an additional DC input are available.
VT855t is designed for use in large data centers and technical infrastructure environments.
