3.1 Direct supply via a MINI Analog signal conditioner
In the case of direct supply, all modules connected to the TBUS DIN rail connector are
supplied via the supply at a signal conditioner. Please note that the maximum total
current consumption of I
max
= 400 mA must not be exceeded and the maximum number
of modules is therefore restricted to a few devices. For the respective current consump-
tion of the individual signal conditioners, please refer to specifications on the
Phoenix Contact homepage, the packing slips or the data sheets. The maximum number
of devices can be calculated using the formula below:
A 500 mA fuse should be connected upstream as protection. In addition, you must make
sure that with the 24 V DC supply used the fuse will definitely trip in the event of an error.

Example for direct supply via a module
The goal is to supply five MINI MCR-SL-PT100-UI-200-NC temperature measuring
transducers (item no. 2864370) and three configurable MINI MCR-SL-UI-UI-NC signal
conditioners (item no. 2864150), with 4 mA ... 20 mA current output at an operating
voltage of 24 V DC.
First determine the current consumption of the modules from the packing slips. For the
temperature measuring transducers it is 21 mA per module and for the configurable
transducers it is 19 mA at the desired current output.
