The IsoBlock I-ST is a sensor designed for high-quality isolated current measurements up to 100 Amperes. The IsoBlock I-ST module provides 1500V primary-to-secondary sustained isolation, which allows users to monitor a miscellaneous of currents at different potentials. The IsoBlock I-ST uses an anti-aliasing filter and a conditioning stage to output a ±10V signal. 



Shunt Methodology 

The IsoBlock I-ST uses shunt methodology to measure the current flowing through the input conductor. In essence, this technique works by placing a high-performance low impedance resistor along the current path (primary), while a galvanic isolation separates primary and secondary sides. The input current is then obtained by amplifying the voltage induced across the shunt resistor.

Compact Form Factor

The compact form factor of the IsoBlock I-ST module allows users to setup high channel density monitoring systems, making it ideal for deployed and portable 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.
