IsoBlock V
Galvanicaly Isolated Differential Voltage Sensor
OVERVIEW
The IsoBlock V module has been designed to provide high-quality isolated differential voltage measurements for aplications requiring scaling of high voltages, as well as superior isolation.
Each IsoBlock V unit hosts four separate isolated channels, each of which can be connected to
separate measurement sources while providing a range of functional coverage up to 1500V. The
input of each specific IsoBlock channel has its own isolated reference, and can be configured to suit
user needs. All processed signals output from the IsoBlock unit are referenced in respect to the
ground channel of the user’s data acquisition system.
Verivolt designs its IsoBlock V modules with consideration for user great flexibility, high channeldensity and low power consumption.

DESCRIPTION
The IsoBlock V module is designed to isolate and scale down
high voltages found in industrial enviroments. The end result is
a signal ready to connect to any data acquisition system, while
galvanically isolating the source from it.
Each channel of the IsoBlock module has a galvanic isolation
from the input to the output that can eliminate large common
mode voltages. In addition to that, each channel also has a protection stage at the input that guards it from surges.
Following the input surge protection stage, there is an amplification stage that brings the input signal to a ±10V range. This signal
is modulated into a magnetic field, and then transferred across a
galvanic barrier. A demodulating stage recovers the original signal, followed by an anti-aliasing filter and a conditioning stage to
output a ±10V differential pair. The figure below shows a block
diagram of the process decribed above.

CONFIGURATION
A. Connect external power source
to power the unit. For proper functioning the power supply should provide a
voltage between 8V and 28V with at
least 0.25A of continuous current and
0.5A surge during module start-up.
