1 Introduction
Before you start to install the 1-Wire Extension 5 and put the device into operation, please read this manual
carefully until the end, especially the section of the safety instructions.
2 Product Description
The 1-Wire Extension 5 is designed as local distributor for 1-Wire temperature sensors with RJ12 connector.
In combination with the different cable lengths of the temperature sensors a simple and fast cabling of up to
5 temperature sensors is possible, e.g. in the area of a heating system or industrial plant.
The design of the outputs with RJ12 sockets eliminates errors compared to distributors with clamp
connections or "luster terminals".
The cable temperature sensors and the 1-Wire Extension 5 form a coordinated cabling system.
As further system components for the 1-Wire network, we recommend the use of a 1-Wire Hub II as power
supply, 1-Wire bus coupler or 1-Wire Controller 1 as coupling to the control computer.
No software is required for this module.

5 Connection 1-Wire network (input)
A screw connection for cable cross sections up to 2.5qmm is provided as input. The screw terminal can be
unplugged to mount the supply cable. For the electrical function only +5V, GND and Data are necessary.
Additionally a terminal for a 12V cable core is provided, this connection is not used internally.
6 Pin Assignment Output Sockets (RJ12) and Connection
The distribution module has 5 outputs with RJ12 sockets. Here 1-Wire cable temperature sensors can be
connected directly.
It is not necessary to remove the plugs, because the plugs of the temperature sensors are connected to the
1-Wire Extension 5 are coordinated.
The output sockets (RJ12 Western socket) are assigned as follows
Assignment RJ12 socket:
1 not connected
2 ground
3 1-Wire Data
4 1-Wire Data
5 +5 V
6 not connected

7 1-Wire Network
For short connection lengths, no special requirements are placed on the cable used. With unshielded cable,
a longer connection length can be achieved in an undisturbed environment, since the capacitive bus load is
lower. A total length of 60 m should be achievable without additional measures.
In a disturbed environment, the cable should be shielded (e.g. CAT5 cable) to improve the interference
sensitivity of the system. Due to the higher capacitive load, the maximum possible connection length is
reduced.
The special feature of the wiring of the sensors is the "BUS technology": All sensors are operated in parallel
on a three- or four-core cable, which is used for power supply and data communication.
Note:You can find basic information and tips on the 1-Wire bus system on the ESERA website at
https://www.esera.de/1-wire-grundlagen/
8 Operating conditions
The module may only be operated at the voltages and ambient conditions specified for it. The device can be
operated in any position. The device is intended for use in dry and dust-free rooms.
If condensation forms, wait at least 2 hours for the device to acclimatize.
The modules may only be put into operation under the supervision of a qualified electrician.
In commercial facilities, the accident prevention regulations of the Association of Commercial Employer's
Liability Insurance Associations for electrical systems and equipment must be observed.
Do not operate the module in an environment in which flammable gases, vapors or dusts are or may be
present.
9 Disposal note
Do not dispose of the device in household waste! Electronic devices must be disposed of
the directive on waste electrical and electronic equipment on local
Collection points for electronic waste must be disposed of!
10 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.
