1 Introduction
Before you start assembling the 1-Wire Hub III DC and before you take the device into operation, please
read this assembly and operating instruction carefully to the end, especially the section referring to the safety
notes.
2 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.

3 Auto-E-Connect® Support
The ESERA Auto-E-Connect® 1-Wire Plug and Play system will be used for the
1-Wire Bus supported. This enables fully automatic configurations of 1-Wire sensors
and actuators on the 1-Wire bus. It is optimized for industrial applications and
enables significant added value beyond the sensor and chip data.
The Auto-E-Connect function automatically recognizes ESERA chips, sensors and actuators, starts suitable
libraries and outputs fully formatted data.
The Auto-E-Connect functionality will be available from mid-2020 via 1-Wire Controllers, 1-Wire Gateways and
1-Wire ECO from ESERA available.
Further information on ESERA Auto-E-Connect can be found on the ESERA website, ESERA Config-Tool 3, or in
the download area for this article in the ESERA Webshop.

8 Software
Output voltage and current are measured by an integrated module. The module is addressed by a standard
command for the DS2450 module. Data output is provided either as Integer values (0 - 4095) or direct voltages,
depending on the used software product. Please refer to the following formulas depending on the data output:
Calculation with output of DS2450 values in Integer
DS2450, 5 V range, output Integer 0-4096 (12 Bit resolution)
voltage 5 V = ((5,0 / 4096) * 1.11) * DS2450_Port3
voltage 12 V = ((5,0/ 4096) * 2.63) * DS2450_Port1
current 5 V = (5,0 / 4096) * (DS2450_Port2 –20) * 46
current 12 V = (5,0 / 4096) * (DS2450_Port0 –20) * 46
Calculation with output of DS2450 analog values in mV
DS2450, 5 V range, 12 Bit resolution
voltage 5 V = (DS2450_Port3 * 1.11) / 10
voltage 12 V = (DS2450_Port1 * 2.63) / 10
current 5 V (mA) = DS2450_Port2 / 20
current 12 V (mA) = DS2450_Port0 / 22

14 Safety instructions
When using products that come into contact with electrical voltage, the valid VDE regulations must be observed, especially
VDE 0100, VDE 0550/0551, VDE 0700, VDE 0711 and VDE 0860
All final or wiring work must be carried out with the power turned off.
Before opening the device, always unplug or make sure that the unit is disconnected from the mains.
Components, modules or devices may only be put into service if they are mounted in a contact proof housing.
During installation they must not have power applied.
Tools may only be used on devices, components or assemblies when it is certain that the devices are disconnected
from the power supply and electrical charges stored in the components inside the device have been discharged.
Live cables or wires to which the device or an assembly is connected, must always be tested for insulation faults or
breaks.
If an error is detected in the supply line, the device must be immediately taken out of operation until the faulty cable
has been replaced.
When using components or modules it is absolutely necessary to comply with the requirements set out in the
accompanying description specifications for electrical quantities.
If the available description is not clear to the non-commercial end-user what the applicable electrical characteristics
for a part or assembly are, how to connect an external circuit, which external components or additional devices can
be connected or which values these external components may have, a qualified electrician must be consulted.
It must be examined generally before the commissioning of a device, whether this device or module is basically
suitable for the application in which it is to be used.
In case of doubt, consultation with experts or the manufacturer of the components used is absolutely necessary.
For operational and connection errors outside of our control, we assume no liability of any kind for any resulting
damage.
Kits should be returned without their housing when not functional with an exact error description and the
accompanying instructions. Without an error description it is not possible to repair. For time-consuming assembly or
disassembly of cases charges will be invoiced.
During installation and handling of components which later have mains potential on their parts, the relevant VDE
regulations must be observed.
Devices that are to be operated at a voltage greater than 35 VDC / 12mA, may only be connected by a qualified
electrician and put into operation.
Commissioning may only be realized if the circuit is built into a contact proof housing.
If measurements with an open housing are unavoidable, for safety reasons an isolating transformer must be
installed upstream or a suitable power supply can be used.
After installing the required tests according to DGUV / regulation 3 (German statutory accident insurance,
https://en.wikipedia.org/wiki/German_Statutory_Accident_Insurance) must be carried out.
