1 Introduction
Before you start assembling the Analog Output and before you take the device into operation, please read these
assembly and operating instructions carefully to the end, especially the section referring to the safety notes.
2 Product description
With the Analog Output, a DC voltage in the range of 0-10V with a resolution of 8 bits can be easily output. This
DC voltage can be output for control, e.g. of a heating mixer, dimmer or other power control units.
The analog output is galvanically isolated from the 1-wire bus and the power supply. The isolation avoids ground
loops or effects due to potential differences.
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.

10 Software / Control
The Analog Output 0-10VDC works with a 1-Wire interface of type DS2408 (8-fold I/O device), which is controlled
with the 1-Wire commands typical for this device.
The DS2408 device can display a total of max. 256 states through its 8 outputs, which can be read in internally by
a microcontroller and converted into an analog output signal.
The individual DS2408 outputs have the following values: channel 0 = 1, channel 1 = 2, channel 2 = 4, channel 3
= 8, channel 4 = 16, channel 5 = 32, etc. The outputs are read by a microcontroller and output as analog values.
All 8 outputs to value 0 mean 10V output voltage. All 8 outputs to value 1 (or 255 decimal) mean 0V output
voltage.
This logic is inverted. The active outputs are added according to their value and output as analog values. Details
can be found in our example program in the download area of the shop.
Note:
The Analog Output 0-10VDC module starts after switching on the supply voltage into the standby mode, in which
no voltage (0V) is output. In standby mode the DATA LED flashes.
The module changes to normal operation after a voltage value of less than 10V has been output once. In normal
operation a voltage between 0-10V can be output.
11 Control by 1-Wire Controller / 1-Wire Gateway
The 1-Wire interface of the Analog Output 0-10VDC is controlled by standard commands for the device DS2408.
The Analog Output 0-10VDC can easily be controlled via a 1-Wire Controller / 1-Wire Gateway. The following
command is available for this purpose.
11.1 Set analog output
Use the following command to set a new analog value.
Command
SET,OWD,OUTA,OWD-number, output voltage
Example: SET,OWD,OUTA,1,1000 => OWD1,10,00V
11.2 Data output 1-Wire controller / 1-Wire gateway
For the 1-Wire Analog Output module 0-10V, the following data are output for the status of the analog value.
The following formatting is available since firmware 1.18_43.
data output
1_OWD1|1000 => Controller No._device No._data record | analog value, example 1000 = 10,00V
Further information in regards to options and commands can be found in the current 1-Wire Controller /1-Wire
Gateway documentation.
12 Operating conditions

15 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.
