EXTENDED PRODUCT FAMILY
Andivi U-DDC has been devloped for several areas of application. As a product family Andivi U-DDC further more extentes with two products;
Connectivity between the Andivi U-MIO input-output unit and the Andivi U-DDC controller
Controller U-DDC can be connected to multiple U-MIO input-output units.
Option 1: The U-DDC controller can connect up to 5 units of U-MIO by the internal BUS on the DIN rail ((I2C).
Option 2: The U-DDC controller can connect up to 4 Modbus RS-485 BUS lines and on each of the lines up to 32 input-output U-MIO units (up to 128 U-MIO units per one U-DDC).
U-DDC and U-MIO provide robust and high-performance integrated solution that has enormous potential in building automation and it is financially very accessible.
