Description
The VT440 extension unit allows for increasing the number of dry contact input terminals connected to any Vutlan monitoring unit. Each VT440 adds 32 dry contacts, providing scalable monitoring capabilities for complex infrastructures. It can be easily connected to any CAN port within a CAN bus chain and can be daisy-chained with other CAN sensors, ensuring seamless integration and flexible system expansion for enhanced monitoring and control.
The number of dry contacts inside VT440 can be increased up to 64 with an extension module "VT32 / dry contacts module".
CAN devices and sensors can be chained together. Up to 10-32 CAN devices can be connected in a chain. You can connect CAN sensors or extensions 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.
Systems with CAN ports:
To read data from the CAN sensors, you need a Vutlan monitoring and control system. A monitoring system may have x1 or x2 CAN ports.
