Product description
The 8-fold Digital Input Module can be used to query the status of 8 switches, reed contacts or all kinds of digital
sensors. The LED indicators on the front panel show the status of the switch inputs. When the input voltage is
present, the respective LED indicator lights up.
To protect the inputs additionally against disturbances, the module has filters with a delay of only 30ms.
Each input can be set manually by pushbutton for test purposes, maintenance or development.
The inputs are isolated from the 1-Wire Network by Optocouplers. This allows very long connection cables
between the module and the sensors without interfering with the 1-Wire Bus.
In addition, the isolation between switch inputs and 1-Wire Network provides increased safety.
For the operation of the Module only a 2V supply voltage is necessary. For this, we recommend the use of one
of our 1-Wire Hub module.

Note
Basics and Tips on the 1-Wire Bus system can be found in the ESERA Online Shop under
1-Wire Basics or please refer to our eBook in the shop under Training/Documentation.
Note
Only a 12V supply voltage is required to operate the module.
For power supply we recommend a 1-Wire Hub device. Input voltages above 30V can cause permanent
damage to the module.
