Product description
The 1-Wire Hub III DC serves as the central power supply within a 1-Wire network. The 1-Wire Hub III DC is
providing the required bus voltage (5 V / 12 V) and also distributes the 1-Wire data line. The 1-Wire Hub III DC is
normally required only once in a network and is connected directly to a 1-Wire Bus Coupler or 1-Wire Controller.
Due to the input voltage range of 18 – 36 V, the device is ideally adapted to the system environment of PLC
controls, for 24 VDC supply.
To operate the 1-Wire Hub III, an upstream system power supply, providing the input voltage of 24 V, e.g. a DIN
rail power supply, is necessary.
The 1-Wire Hub III DC is equipped with a measuring function for the output voltage and current of the 5 V and 12
V output by default. This is measured by an integrated 1-Wire module (DS2450). Due to voltage- and current
measurements, issues with the supply of a 1-Wire network, such as overload or short circuit, may be detected at
an early stage.
The 1-Wire Hub III DC is designed for a broad supply range of 18 – 36 VDC (nominal 24 VDC).
As an "emergency power supply" for a 1-Wire network, the 5 V input voltage is provided in only one direction to
the output, even when there is no 24 V supply voltage available. This is to ensure a minimum function of the
1-Wire network, even in the event of failure of the 24 V main supply. In this operating mode the 12 V voltage is
not available.
Output power of the 1-Wire Hub III DC is designed to hold up to 40 modules.
8 devices of 1-Wire air quality sensors (11127) and 8 devices of 1-Wire 8-way switch modules (11220 (8x8A) or 6
devices of 11228 (8x16A)) can be connected.
The device is designed for DIN top-hat rail mounting in a switchboard.
