Product Overview
MODBUS ND06is adigital integrated current transformer, which integrates the signal acquisition, analog-to-digital conversion, and digital communication of traditional current transformers (CTs) into a compact module. By using RS485 Modbus communication, digital current measurement values can be directly output without the need for the analog input module (ADC) of the PLC, greatly simplifying the wiring and configuration of the power monitoring system.
Comparison between Traditional CT and Digital CT
| Comparison | Traditional CT | ND06 Digital CT |
|---|---|---|
| Output Signal | 0-1A or 0-5A AC Current | RS485 Digital Signal, Directly Output Current Value (A) |
| Wiring complexity | Requires ADC module+transmitter | Only 2 RS485 wires+power supply |
| Accuracy maintenance | Affected by long line transmission attenuation | Digital signal lossless transmission |
| Data acquisition | Requires PLC/data collector ADC channel | Directly read by any Modbus master device |
