Product Datasheet

The VT408 is an extension unit that increases the number of analog sensors connected to any Vutlan monitoring unit. Each VT408 adds 8 analog sensor ports, allowing for greater scalability in monitoring complex environments. Multiple VT408 units, along with other CAN devices or sensors, can be daisy-chained via the CAN bus port for efficient expansion. All connected sensors are automatically detected and integrated into the system, simplifying setup and ensuring seamless critical infrastructure monitoring.

Up to 10-32 CAN devices can be connected in a chain. You can connect CAN sensors or extensions on a CAN bus line.

Up to x24 VT408 units can be connected on a CAN bus line. CAN-12V-1A / CAN Power Supply has to be used to provide additional power on a CAN bus line.

Connecting CAN sensors

You can connect up to x32 CAN units in a CAN bus chain.

E.g. Each VT408 unit in a CAN bus chain adds 8 analog sensors.

E.g. Each VT440 unit adds x32 or x64 dry contact inputs to the system.

The additional power supply CAN12V-1A is needed only if the number of sensors in a CAN bus chain is more than 12 sensors. Supplies power for each additional group of 12 sensors.
