Sensor ports
Connect sensor by a supplied RJ-11 (6P4C) cable to any sensor port "A1 .. A4". The determination of the sensor type and connection will occur automatically.
Temperature sensor
A temperature sensor is built-in on the VT335 DC board and sticks out on the front panel of the unit for better measurement. Accuracy equals +/- 1°C.
12V outputs
The module has two 12V 0.25A outputs (electronics relays). E.g. the appliance has the possibility to connect flashlights or sirens managed by a built-in electronic relay.
CAN port
Connecting CAN devices on a common bus allows you to collect data from the sensors with a large area, or from a large distance and to transmit them to the network.
Dry contact inputs
VT335S has 4 dry contact inputs. It can be used together with any contacts, for example with door or window contacts, circuit breakers, etc.

Allows to monitor up to 32 Modbus RTU devices/meters/sensors. Max. a distance of a daisy chain is up to 1000 meters. Each metered value of a Modbus device is addressed individually using input registers and is shown by the system as virtual sensors. You can configure thresholds and icon representation for these elements.
It can be used with VT325, VT335S, VT805, VT825 monitoring systems. Installed inside the monitoring unit. Has an internal termination and by default, it is switched ON (if required can be turned off).

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 700 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 VT740 LTE slot modem (sold separately) for an ethernet connection reservation. Has two power inputs for power reservation (i.e. battery plus main power supply).
