VT855ii / Redundant monitoring unit

MSRP price: €945.00

Monitoring system with redundant power supply

The unit 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, alarms). Can use up to 1000 different elements - notifications, triggers, timers, logic schemes, sensors, dry contacts. Has built-in Web interface with virtual sensors, logic schemes, different types of notification, and control panels. Has a slot for a VT790 LTE Slot modem (ordered separately!) for an ethernet connection reservation.

Order option:

VT855ii has 2 power inlets, providing a redundant power supply for A&B power distribution.  Power input can be chosen.
