The external supply voltage 2P24 is connected at connector –X35. This voltage, supplied from a 10 A power supply unit, is
selectively distributed via several single-pole miniature circuit-breakers. Their auxiliary contacts can be wired to HK_1 and
HK_2. In addition, a further external power supply 2P24_2 can be monitored for undervoltage.

Signal processing
Tasks of the operational amplifier
The Power Stack Adapter returns analog signals within a range of values from 0 V to 10 V to
the DM10 diagnosis module. Because of this fixed value range, signed signals such as the
actual speed value cannot be represented. Eight AD8674 operational amplifiers boost the
voltage signal (reduced by 5 V) by a factor of 2. As a result of this signal handling, it is also
possible to represent signals in a range of values from -10 V to +10 V.
In order to be able to perform signal handling with great accuracy, the operational amplifiers
must satisfy the following criteria:
● Low noise: 2.8 nV/√Hz
● Large bandwidth: 10 MHz
● Low quiescent input curent: max. 12 nA
● Low offset voltage: max. 75 μV
The signals are relayed to the following interfaces:
● For diagnosis to the process data acquisition system (option G66).
● For alternative diagnosis with the aid of indicating instruments (option K21/K22).
● Via additional isolation amplifiers to the control station / I&C.
● For simplified diagnosis with an oscilloscope to measuring sockets X20 to X27.
