1 Introduction
Before you start assembling the Switch Module and put the device into operation, please read this assembly and
operating instructions carefully to the end, especially the section referring to the safety notes.
2 Product description
With the 8-fold switching module direct and alternating current consumers with a current of up to 8A continuous
current per channel and a total of 10A can be switched.
The 8-fold switching module can be controlled directly by an external push button (e.g. light switch) or by a push
button menu on the top of the module, also independently of the 1-Wire interface. For this switching function by
push button it is sufficient if the 12V supply voltage is applied. This ensures an extremely high reliability, e.g. for
switching lights, socket circuits or other important consumers, even if a central control unit / software fails.
The relays switched via the push button interface or by manual operation can be read back via the 1 Wire interface.
Also the status of the push button interface can be read back.
To supply the switch module we recommend the use of one of our 1-Wire Hub modules.

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 Operating mode, display and operation
The module has two modes of operation: normal mode and manual control mode.
Normal mode: After start-up, the device is in normal operation mode. This means that a command is applied
directly by the 1-Wire interface to the appropriate output relay. The respective output LED is lit.
Manual control mode: By pressing the button „MAN/Select“ for 2 seconds, the module switches to manual
control mode (manual operation). The „PWR“ LED flashes to confirm selection of manual control mode.
Press the "MAN / Select" key briefly to select an output. The LEDs 1-8 light up for the selected output. Press the
"ON / OFF" key to switch the selected output on or off.
Several outputs can be switched in one cycle.
After a waiting time of approx. 2 seconds, the system automatically switches to the operating mode "normal
operation", the "PWR" LED lights up again permanently and the selected outputs are activated.
Delete "Manual operation": Pressing the "ON/OFF" key for 2 seconds switches off the outputs selected in
manual operation.

9 8-fold digital input, pushbutton Interface
In addition to the manual mode (module top side), and the 1-Wire interface, the module also has
8-fold pushbutton interface, 8 x digital / binary input, for switching the outputs.
To switch an output, a short input signal (keystroke) to the corresponding input is sufficient.
The 8-fold pushbutton interface is intended for switching lights, actuators for radiators or sockets in the living area
by e.g. light switches or motion detectors with pulse output. This ensures fast switching even with no system
control available.
The impulse control, comparable to a staircase lighting timer, allows any number of light sensors and motion
detectors to be connected at the same time.
Further details on the ESERA-Automation lighting system can be found on the following website:
https://www.esera.de/smart-home/anwendungsbeispiele/lichtsteuerung/
Besides light scanners, any other pulse control signal can be used to switch the outputs.
All three interfaces, manual operation, 1-Wire and push button interface, operate in parallel to the outputs. An
output switched e.g. by the 1-Wire interface can be switched off or on manually or by push button interface.
The pushbutton interface can be used for example to connect light scanners for light on/off control. Normal light
scanners of all switch manufacturers can be used for this purpose.
Within the module a µController takes over the query of the buttons, the 1-Wire interface and the control of the
relays. The button interface is queried via edge scanning.
The outputs switched via the pushbutton interface or manual operation can be read back via the 1-Wire interface.

10 Software / Control
The 1-Wire interface of the 8-fold digital output 8/8 is controlled by standard commands for the DS2408 module.
The outputs switched via the pushbutton interface or manual operation can be controlled via the
1-Wire interface can be read back.
11 Control by 1-Wire Controller / 1-Wire Gateway
The 1-Wire interface of the 8-fold digital output 8/8 is controlled by standard commands for the DS2408 device.
The outputs switched via the pushbutton interface or the manual mode can be read back via the 1-Wire interface.
The 8-fold switching module can be controlled very easily via a 1-Wire controller / 1-Wire gateway. Two
commands are available for this purpose. Below are the two commands.
11.1 Switching an output relay
To switch a relay output, use the following command, which only sets the selected output to 0 or 1.
Command: SET,OWD,OUT,OWD-Number,Output,Value
Example: set,owd,out,2,1,1 => OWD Number 2, output 2 will be switched to “on”.
After switching the output latest status will be output as confirmation.
11.2 Switching of all output relays (Port)
There are applications and modules where it is necessary to switch all outputs with one command.
With one command, all outputs of the 1-Wire module are set to a specific state, which means that the previous
output state is overwritten.
The 1-Wire Controller / the 1-Wire Gateway takes over the command adaptation to the connected
Module 8-fold switching module.
The output value is output as decimal value 0-254. Each relay output has a valence which is summed up.
Output 1 = 1, Output 2 = 2, Output 3 = 4, Output 4 = 8, Output 5 = 16, Output 6 = 32,
Output 7 = 64, Output 8 = 128.
For example, if you want to switch Output 1, 3 and 5 to 1, add the output value together.
Here e.g. 1 + 4 + 16 = 21
All other relay outputs are switched to 0. If all outputs are to be switched to 0 or off, the output value is 0.
Permissible output values for 1-Wire digital outputs: 0 - 255
Command: SET,OWD,OUTH,OWD-Number, value
Example: set,owd,outh,2,15 => OWD Number 2, outputs 1 to 4 will be switched to “on”.
After switching the output, latest status will be output as confirmation.
11.3 Data Output 1-Wire Controller / 1-Wire Gateway
For the 8-fold digital output 8/8, the following data is output for the binary / digital inputs (button interface) and
relay outputs.
The input and output values are output as decimal value 0-254 and in a second data set binary with 0 and 1.
Each input and output has a valence, which is added up in each case.
Input pushbutton interface:
Input 1 = 1, Input 2 = 2, Input 3 = 4, Input 4 = 8, Input 5 = 16, Input 6 = 32, Input 7 = 64,
Input 8 = 128.
Relay Output:
Output 1 = 1, Output 2 = 2, Output 3 = 4, Output 4 = 8, Output 5 = 16, Output 6 = 32, Output 7 = 64,
Output 8 = 128.
