The IsoBlock I-ZF is a sensor designed for high-performance current measurements with ranges from 10A to 2000 Amperes. The IsoBlock I-ZF consists of 2 parts, a toroid and a DIN rail mounted conditioning unit. As all devices from the IsoBlock family it has an anti-aliasing filter and a conditioning stage to output a ±10V signal. The sensing unit uses Hall Effect with closed loop methodology to measure the current flowing in the conductor passing through the aperture. This is followed by translation, corrections, scaling and anti-aliasing filter in the conditioning unit.
Compact Form Factor
The compact form factor of the IsoBlock I-ZF module set allows users to setup high channel density monitoring systems, making it ideal for high performance compact systems.
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.
Three-Way Galvanic Isolation
The IsoBlock I-ZF is a non-contact sensor that inherently provides primary-to-secondary isolation, which allows users to monitor a miscellaneous of currents at different potentials.
