The IsoBlock module was designed to provide low-cost and high-quality isolated differential voltage measurements along a chain of fuel-cells or batteries. Our innovative modular architecture and isolation techniques allow users to connect multiple IsoBlock modules together serially, facilitating the monitoring of long fuel-cell or battery chains.

Each IsoBlock unit hosts eight separate isolated channels, each of which can be connected to separate measurement sources while providing a range of functional coverage up to 20V. 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 modules with consideration for user flexibility, exceptionally high channel-density and low power consumption.

Flux Gate Methodology

The IsoBlock I-FG-4C uses Flux-Gate methodology to measure the current flowing through the input conductor. This technique works by placing a toroid with a high number of turns (secondary) around the input current path (primary), while a close-loop circuitry controls the current through the secondary to null out the magnetic field inside the toroid. The input current is then obtained by multiplying the current from the control circuitry by the number of turns of the secondary. This is followed by an anti-aliasing filter and a conditioning stage to output a ±5V signal.
