Product description
The 1 Wire Serial Bus Coupler USB V3 establishes a stable, electrically isolated connection among a 1-Wire
network and a computer. Special feature of the 1-Wire Bus Coupler USB V3 is an external voltage supply. Thus,
operating safety of the data connection to a computer will significantly be enhanced. Issues caused by unreliable
USB voltage supplies will be avoided. The use of more expensive USB hubs is no longer necessary.
The 1-Wire output of the bus coupler is isolated among the USB data supply and the voltage supply. Thus,
ground loops or EMC emissions and grounding issues from a computer to the 1 Wire network are efficiently
prevented. The isolation significantly reduces stray radiations ("electric smog") in living areas and enhances
electric safety among the systems. For galvanic isolation state-of-the-art high-speed optocouplers and special
isolated power adapters are being used. Even the 1-Wire „data" LED is isolated controlled by optical coupler
The 1-Wire component DS2480 from Dallas/Maxim is used within the 1-Wire Bus Coupler. This component,
combined with the complex internal voltage supply, is the basis for a very stable 1-Wire network. The DS2480
component supports the „Strong Pull Up" function and is thus predestined for the use in large 1 Wire networks as
well.
For the voltage supply, the 1-Wire Bus Coupler has a wide-range input of 9-32VDC and is thus equally suitable
for 12V systems and typically industrial 24VDC supplies. You can find compatible top-hat rail power adapters or
socket power adapters in our webshop.
Individual 1-Wire sensors can be connected directly. For major 1-Wire networks it is recommended to use a
1-Wire Hub III.
Please refer to the connection plan for further details in regards to the electric connection.
