Hardware Manual COMBILOG 1020

This kind of bus connection and of power supply is particularly
advantageous if several dataloggers are mounted on one com-
mon profile rail side by side. In this case the connection via the
terminals can be dropped, except for one module.
Note:
It is necessary to take care that the current at the Module
Jack is not higher than permitted. Thus, the power supply pref-
erably should be led to the centre of the module line. For the
same reason, it is not allowed to connect more than 6 datalog-
gers via the Module Jacks in one line.
