1 Introduction
Before you start assembling the 8-fold 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 Switch Module it is possible to connect direct power consumers and alternative power consumers
with an output of up to 8A continuous power.
The switch module can be controlled directly by an external button (e.g. light switch) or by button-menu on the
module top side, independent of the 1-Wire interface For switch operation only 12 V power is required. Thus, a
high reliability, e.g. for switching of lightings, outlet circuits or other consumers can be reached, even in case of a
breakdown of a central control / software.
To operate the switch module we recommend the use of one of our 1-Wire Hub modules.
3 Technical data
Switching channels: 8, changeover relay (NO contact)
Switching voltage: Maximally 250V direct power voltage or alternative power voltage
Switching power/Power: Maximum 8A continuous power per output and maximally 1840VA continuous power
in case of Ohm resistive load.

In case of capacitive or inductive loads, appropriate additional wirings, e.g. spark
suppressor capacitors must be considered. Maximum power and output will be reduced.
Fuses: External preliminary fuse with 10A recommended
Data interface: 1-Wire Bus (12V, data and load)
1-Wire Component: DS2408 (8-Fold I/O)
Supply voltage: 12VDC (+/-10 %)
