Interface Modules

The Cortex interface module ecosystem connects seamlessly to the CSM monitor series through flexible expansion options for current sensing, digital inputs and peripheral monitoring.

CS-Series

Solid Core CT Strip
Advanced Branch Circuit Monitoring

The CS-Series is a next generation branch circuit monitoring solution with 0.2 class accuracy and true per-circuit waveform capture. Each strip clips onto the DIN rail inside the panel with 21 x 100A solid core CTs and 3 auxiliary inputs. A single Cortex monitor supports up to 8 strips for 192 circuits total.
