Function and purpose
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.
Usage
Dry contact usage examples:
General Alarm
System Healthy status
System Common Fault Alarm
Door open/closed
A window opened/closed
HVAC on/off state
Power supply control (controls On/Off state of any connected devices)
Order options
VT440 can be ordered in two options:
a) VT440 (x32 dry contact inputs)
b) VT440 + VT32 (x64 dry contact inputs)
Physical description
1. "1...32" - Dry contacts terminal.
2. "33...64" - Dry contacts empty slot. VT32 / Dry contacts board is ordered separately.
3. "S/N" - serial number. You will need this serial number if you want to contact our support team. You mustn't lose it!
4. LEDs: "RUN" - indicates appliance connection status to the main module, "ERR" - indicates appliance lost connection to the main module.
5. "CAN 1", and "CAN 2" - two equivalent digital connectors RJ12 for the connection to the master module, CAN sensors, or CAN extensions on a CAN bus, with auto-sensing.
6. "TR" - is the nearest switch to CAN inputs. This switch should be turned "ON" on the last sensor in the CAN chain. The last sensor in the long chain with a length of more than 10 meters, the terminator should be in the "OFF" position.
Do not use the DIP switch "FR" labeled "1", it should always be OFF. If this switch is turned ON, the module will turn off. This switch is only needed for programming purposes

Installation
"TR" - is the nearest switch to CAN inputs. This switch should be turned "ON" on the last sensor in the CAN chain. The last sensor in the long chain with a length of more than 10 meters, the terminator should be in the "OFF" position.
pic.2.1: TR is ON, FR is OFF. pic.2.2: TR is OFF, FR is OFF.
