Function
A DC isolating amplifier with galvanic isolation and three-way separation is used to transfer
analog output signals with electrical isolation.
The isolating amplifier is wired to one of the analog outputs at CU1/-X177:49/50 or CU1/-
X177:51/52. The isolating amplifiers have three-way separation and are supplied with 230 V
AC from inside the cabinet.
Display instruments and isolating amplifiers for the output of the same signal, e.g. "armature
current", are connected to the same analog output. For this reason, the signal to be output
(e.g. "armature current", "speed", etc. ) must always be specified.
Note
A universal isolating amplifier is used. When required, the preset (default) input/output
configuration can be changed. A readjustment is required in this case.
Note
Precisely two analog outputs are available for each CUD. This must be observed if more
than two isolating amplifiers are connected, or additional display instrument options B60 to
B62 or B64 are selected, as the latter are also supplied via analog outputs. If required, a
second CUD (option G10 or G11) and/or one or several TM31 Terminal Modules must then
be additionally installed. In this case, the analog outputs that are to be used can be seen
from the order-specific circuit diagram.
Connection
The customer connection is directly established at isolating amplifier XT-T2 (1) at terminals 7
and 9.
Parameter assignment
Isolating amplifiers are preset, no parameterization is required.
Cable routing
The cables are routed into the cabinet corresponding to the following diagrams.
