VT825 DC / Monitoring unit with DC power supply
The unit uses a power supply with two isolated DC +/- 48V inputs. Can use up to 100 different elements - notifications, triggeres, timers, logics, sensors, dry contacts. Possible extensions are 1-Wire board for reader or board with 8 dry contacts, two relais 10A and power backup input.
There are built-in servers and agents like HTTP, HTTPS, SNMP v1, 2c, 3, SMTP, Radius, Syslog, FTP, DHCP, Wachdog.°C.
External power supply is not included in the delivery.
DC power 48V
The unit supplied by 48 V (mostly used by Telecom companies). In case the first power input shut down, the system can automatically start to use the second power input. DC inputs are isolated from the earth! Customer can use either + or - on the ground. Power supply range is 14-70 V.
Sensor ports
Connect sensor by a supplied RJ-11 (6P4C) cable to any sensor port "A1 .. A8". Determination of the sensor type and connection will occur automatically.
Temperature sensor
Temperature sensor is built-in on a board and sticks out on the front panel of the unit for better measurement. Accuracy equals +/- 1°C.
12V outputs
The unit has two 12V 0.25A outputs (electronics relays). E.g. the appliance has the possibility to connect alarm beacons managed by built-in electronic relays.
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. VT825 has a LED for CAN bus status indication.
Dry contact inputs
VT805 has 4 dry contact inputs. Can be used together with any contacts, for example with door or window contacts, circuit breakers etc.

Extension: VT18 (ordered separately)
Board is mounted and connected inside of "VT825 / Monitoring unit". Adds 8 dry contacts (IN), 2 loads (latching relays with LEDs indicators on front panel) & 12V DC power backup terminal. VT825 allows to install either VT18 or VT10, both extension can not be installed at the same time.
Extension: "VT10 / 1-Wire board" (ordered separately)
1-Wire board can be installed insideof monitoring unit to connect access reader or accurate temperature sensors. VT825 allows to install either VT18 or VT10, both extension can not be installed at the same time.
IP cameras
Using built-in interface it is possible to add up to four IP cameras. This will allows to view footagefrom surveillance cameras remotely,
USB camera
One USB camera (class Linux UVC Webcam which supports MPEG) can be connected to "USB" port. More USB devices can be connected to one USB port using USB hub.
USB flash drive
USB flash drive can be connected to VT805 using OTG miniUSB cable and can be used by the system for saving logs. More USB devices can be connected to one USB port using USB hub.
LEDs
"ACT" - indicates appliance status, "E1" - indicates 12V "E1" relay status, "E2" - indicates 12V "E2" relay status, "ERROR»" - indicates error and traffic, "CAN" - indicates BUS status.
Chassis earthing
Chassis external ground earthing, to suppress electromagnetic interference.
LAN
Ethernet 10/100 Base-T port, provides network connection.
