ISOTEL Industrial Classic Series

DC-CT® Industrial Smart Series with Wide Opening

Preliminary Product, available in 2026Q4 - 2027Q1

This series is an industrial, galvanically isolated, precision, closed-loop Smart current transducer based on ISOTEL’s DC-CT® proprietary technology and the patented Platiše Flux Sensor. It integrates IEEE 1451.4 TEDS for plug-and-play self-identification and self-description, ISOTEL I-Wire diagnostic interface, and a fail-safe range/fault signal bringing smart sensor capability to industrial current measurement.

Key features

  • Platiše Flux Sensor Closed-Loop Transducer

  • 10x Performance Compared to Competing Products

  • Excellent temperature stability

  • Standard industrial connection (3 or 4 wire, bipolar supply)

  • ISOTEL I-Wire for Identification, Description, Diagnostic and Fast Primary Tracking Fault

  • Large opening for easy installation, 40 mm bus bar and 38 mm round conductor
