The Envoy SC is a single channel (SC) module designed for high-quality current measurements in the range from 50 to 300 Amperes.
The IsoBlock Current-FG uses Hall Effect with closed loop methodology to measure the current flowing in the conductor passing through the aperture. This is followed by an anti-aliasing filter and a conditioning stage to output a ±10V signal.
The compact form factor of the Envoy SC 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.
