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.
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.
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.
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.
VT335S has 4 dry contact inputs. It can be used together with any contacts, for example with door or window contacts, circuit breakers, etc.
or 
VT335S has the possibility to install the "VT85 / Modbus extension board" or "VT10 / 1-Wire board" extension (ordered separately).
VT335S has the possibility to install "VT85 / Modbus extension board" or "USB485 / RS-485 to USB adapter" exntensions (ordered separately).
Using a built-in interface it is possible to add up to four IP cameras. This will allow viewing footage from surveillance cameras remotely,
One USB camera (class Linux UVC Webcam which supports MPEG) can be connected to a USB port. More USB devices can be connected to one USB port using the USB hub. Cameras can be purchased here.
USB flash drive can be connected to VT335S using OTG mini USB cable. Flash drive is used by the system for saving logs. More USB devices can be connected to one HS USB port using the USB hub.
Order options: a) 12VDC b) 24VDC c) 48VDC
Chassis external ground earthing, to suppress electromagnetic interference.
Ethernet 10/100 Base-T port, provides a network connection.
"ACT" - indicates appliance status, "E1" - indicates 12V "E1" relay status, "E2" - indicates 12V "E2" relay status, "ERROR»" - indicates error and traffic.
Type miniAB USB-port 2.0, Can connect USB camera; or connect a PC for restoring an appliance; or connect USB flash for saving logs.
The holder/bracket for the "VT335S / Monitoring unit" is ordered separately. 1U rackmount, 19".
Brackets for the "VT335 S / Monitoring unit" are ordered separately. The package includes two brackets.
The DIN rail holder for the "VT335 S / Monitoring unit" is ordered separately.

Allows increasing the number of sensors connected to any monitoring unit. Adds 8 analog sensors. Connects on CAN port and allows further CAN daisy chain connection. Sensors connected to the extension unit appear in the system automatically.
The sensor is needed for the measurement of temperature indoors.

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).
