Connection - Relay outputs
The Ser[LOG] has 2 switching outputs "R1" and "R2" in the form of two-way switch relays. Warnings
and alarm messages can be issued via the relays. See also chapter 7.
Important note:
The relays may be loaded with up to 30 V and 0.5 A.

The relays "R1" and "R2" are bistable, potential-free change-over switches. The signal to be switched
is applied to "C". In idle state (Log 0) there is a switching connection to "S0", in switched state (Log 1)
there is a switching connection to "S1".

Connection - AnDiMod Module
Ser[LOG] and Ser[LOG]Plus can be extended by additional measurement modules AnDiMod. Each
AnDiMod contains 12 differential measuring analogue channels and 3 digital channels.
The connection is made via the Ser[LOG] bus. The AnDiMod modules occupy the COM6 interface and
are no longer available for other devices. As soon as the AnDiMod module is activated via the Ser[LOG]-
Commander, the COM6 terminal on the front panel is deactivated.
The Ser[LOG]-Bus is available for all devices of the Ser[LOG] family and is located at the bottom of the
housing. The 4 terminals are used to connect the power supply and the data lines.

There are three different AnDiMod expansion modules. The modules AnDiMod 1-3 differ in their address
on the Ser[LOG]-Bus. If a Ser[LOG] system is to be extended by an AnDiMod, it is necessary to check
beforehand how many modules have already been connected and to select the corresponding module
with the correct address (numbering following). The first module that can be used to expand a Ser[LOG]
must have the address 1. The first module that can be used to expand a Ser[LOG]Plus must have the
address 2, since an AnDiMod with the address 1 is already integrated in the Ser[LOG]Plus. An AnDiMod
module with address 3 can only be connected to the Ser[LOG] if the AnDiMod modules with address 1
and address 2 have already been connected to the Ser[LOG] bus. If a module is missing in the se-
quence, this leads to a system error and the Ser[LOG] does not work!
