1 Introduction
Before you start to install the Dual Switch Module and put the device into operation, please read this operating
manual through to the end, especially the section on safety instructions.
2 Product description
With the Dual Digital switching module, direct and alternating current consumers with a capacity of up to 10A
continuous current can be switched. It is also possible to control motors, such as roller shutter drives.
The switch module can be controlled directly by an external switch (e.g. light switch) or by a switch 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 extremely high reliability, e.g. for switching lights, socket circuits or
other important consumers, even if a central control unit/software fails.
The installed high-performance relays can be operated in a special power saving mode to reduce the power
consumption. This can reduce the current consumption of the two output relays by approx. 40 %.
To supply the switching module we recommend the use of one of our 1-Wire Hub modules.
3 Energy-saving mode
The Dual Switching Module has a modern energy saving mode for the output relays. The energy saving mode
can be switched on or off via key 1 (module top side). The energy saving mode is deactivated at delivery. The
selected setting remains permanently stored, even after a power interruption. Depending on the function, quiet
noises may be audible with active output relays in energy saving mode. If these are disturbing, e.g. when
operating in the living room, you should switch to normal mode.

10 Button and 1-Wire Interfaces
In addition to the buttons on the top side of the module, the module has an external button-interface to connect
two external buttons (make contact). This means, light switches can be connected to the external button interface
to control on/off light commands. For connection regular light switches of all manufacturers can be used.
Within the module, a µ-controller takes over the query of the buttons, the 1-Wire interface and the control of the
relays. Flank control is used to query buttons and 1-Wire component.
The switching status of the relays can be set via the external and internal buttons. Relays can also be set by the
1-Wire Interface.
The state of the relay that has been triggered by the button cannot be read by the 1-Wire interface.
Button 1 on the module has a double function. For details refer to chapter „Energy-saving mode“.
External and internal control inputs:
Button interface, external button 1
Button interface, external button 2
Module top side, button 1 internal / Mode: Energy saver mode/Normal mode
Module top side, button 2 internal
1-Wire Component, DS2413 channel 0
1-Wire Component, DS2413 channel 1
No voltage source may be connected to the external push-button interface. The connecting cables between
module and push button must be laid isolated from other cables. 5V DC voltage is applied to the connections of
the pushbutton interface when not in use.
11 Software / Control
The module is controlled by 1-wire commands for the DS2413 module.

12 Control via 1-Wire Controller / 1-Wire Gateway
The 1-Wire interface of the Dual Digital Switch Module is controlled by standard commands for the DS2413
module. Outputs switched by the pushbutton interface or in manual mode cannot be read back by the 1-wire
interface. The dual digital switching module can be easily controlled by a 1-wire controller / 1-wire gateway. For
this purpose the following two commands are available.
12.1 Switching of an output relay
To switch a relay output, use the following command to set only the output selected 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.
12.2 Switching of all output relays (Port)
Some applications require switching all outputs with one command.
The following command sets both outputs of the 1-Wire device to a desired state. The 1-wire controller / 1-wire
gateway handles the command adaptation to the connected Dual digital switching module.
Output value is displayed as a decimal value 0-3. Each relay output has a significance, which is added up.
Output value 0 = all off, 1 = output 1 active, 2 = output 2 active
If output 1 and 2 should be switched to "active", add up the output values
Example: Output value: 1 + 2 = 3
Permitted output values for 1-Wire digital outputs: 0 - 3
Command: SET,OWD, OUTH,OWD-Number, Output Value
Example: set,owd,outh,2,3 => OWD Number 2, outputs 1 and 2 will be switched to „Active“
After switching the output latest status will be output as confirmation.
12.3 Data output 1-Wire Controller / 1-Wire Gateway
For the Dual Switch Module the following data are output to display relay status.
Data output:
1_EVT|12:27:40
1_OWD2_1|0 => controller no._module no._data set|status output 1
1_OWD2_2|1 => controller no._module no._data set|status output 2
Further information for options and commands can be found in the latest available documentation for
1–Wire Controller / 1–Wire Gateway.
