“VT855t / Data Center Monitoring System” is used for environmental monitoring (e.g. temperature, humidity, voltage, leakage, smoke, airflow). It is also used as an I/O controller (e.g. door control, fans, generator, control panels, UPS, circuit breakers, and alarms). Can use up to 1000 different elements - notifications, triggers, timers, logic schemes, sensors, dry contacts. Has a built-in Web interface with virtual sensors, logic schemes, different types of notifications, and control panels. Has a slot for an LTE modem for an ethernet connection reservation.

Includes x8 analog sensor ports, x1 Ethernet port, x1 Micro USB port, x1 CAN sensor bus port, x2 NC/NO/COM relays, x2 12V DC 0.25A relays, x32 dry contact inputs, x8 dry contact outputs, x1 SD card slot, power reservation option for AC and DC, LTE extension slot, Modbus RTU or OSDPv2 reader extension slot.
