1 Introduction
Before you start the installation of the ESI400 module (in the following only ESI400) and put the device into
operation, please read these installation and operating instructions to the end, especially the section of the
safety instructions.
ESI stands for ESERA Switch Input.
2 Product Description
With the ESI 400 the status of 4 switches, reed contacts or all kinds of potential-free digital sensors can be
queried. No external voltage is required for the inputs.
The status LED on the upper side of the module signals the power supply and the status change of the inputs.
When input voltage is applied, the LED flashes briefly as confirmation of the status change.
The ESI 400 is equipped with hardware and software filters to reliably interrogate all types of mechanical switches
without flickering. The delay of the inputs is about 40ms.
The inputs are electrically connected to the 1-Wire network. Due to the complex filter technology, even long
connection cables between the module and the sensors are possible without disturbing influences on the inputs
and the 1-Wire bus. The working voltage of the digital inputs is approx. 5V.
The ESI 400 has a universal supply voltage input with 5V to 12V voltage.
We recommend the use of one of our 1-Wire hub modules.

8 LED display and operating elements
The ESI400 has a green LED for each input channel that lights up when the module is supplied with 5-12V DC. At
startup, the software version and revision of the device software are displayed by a view code (first the version
and then the revision). After about 10 seconds the ESI400 module is ready for operation.

9 Software / Control
The 1-Wire interface of the ESI400 is read out via 1-Wire command for the 1-Wire device DS2408.
The module is a standard module for many systems and software programs, such as 1-Wire controller,
1-Wire gateway, ESERA STATION, PowerDog, SmartOne, FHEM, OWFS, IP-Symcon etc.
9.1 Data output 1-Wire Controller / 1-Wire Gateway / ESERA Station-200
The 1-Wire interface of the ESI400 is controlled by standard commands for the DS2408 read.
For the ESI400 the following data is output for the binary / digital inputs.
The input value is output as decimal value 0-254 and in a second data set with binary display (0 and 1). Each
input has a value which is added up.
Input value:
Input 1 = bit 1 (value 1), input 2 = bit 2 (value 2), input 3 = bit 3 (value 4), input 4 = bit 4 (value 8), bits 5 - 8 are
static 0.
You can assign Art.No.11235 to the DS2408 device via the config tool. After assigning the part number, you will
receive formatted output.
Data output:
1_OWD1_1|2 => Controller No._Module No._Data set | Decimal Value Input
1_OWD1_2|00000010 => Controller No._Module No._Data set | Binary Display Input
For further information on the possibilities and commands, refer to the current documentation
1-Wire Controller /1-Wire Gateway.

13 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.
