Verivolt IsoBlock | Voltage Sensor Module

Product Information "Voltage Sensor Module with Galvanic Isolation | IsoBlock V-4c Series"

Verivolt IsoBlock V-4c Series
Galvanically Isolated Voltage Sensor Module

Voltage Sensor With Intelligent Signal Processing

The IsoBlock V-4c Series is designed as a modern sensor to measure high voltages accurately, even in complex test setups. Each galvanically isolated module is fully compatible with common data acquisition systems and integrates as a flexible add-on in test benches.
As a rugged sensor, the series reliably analyzes quality and delivers repeatable results. With optimized efficiency and high capability, each unit also processes demanding signals—ideal for measuring quality.

Galvanic Isolation for Safe Circuits
The consistent galvanic isolation ensures clean separation of input and output signals. Each channel is fully electrically isolated, keeping separate signal paths protected against feedback. This architecture shields sensitive circuits from interference even at high voltages—an essential advantage for safe, reliable testing.

Current and Voltage Measurement for R&D and Industry

As an innovative and measurement device, the series combines precise and measurement with high safety. It complements classic instruments such as multimeters, digital meters, testers, and voltmeters, and delivers stable results—even with parallel circuits. The IsoBlock V-4c Series combines state-of-the-art isolation technology with flexible integration into any professional test environment.
