Applications

1. Multi-Circuit Power Monitoring

Monitor active power across 3 independent AC circuits with a single 6-channel module. Ideal for distribution panel metering and branch circuit energy tracking.

2. Industrial Automation & SCADA Integration

RS485 Modbus-RTU output connects directly to PLC and SCADA systems. High-speed baud rates up to 115200 bps support efficient real-time polling in large-scale deployments.

3. Control Cabinet & Electrical Enclosure Monitoring

Compact 35mm DIN rail form factor saves space inside electrical cabinets. Monitor incoming mains voltage and multiple branch circuits simultaneously.

4. Energy Management Systems

Combine voltage and current channels to calculate power consumption per circuit. Use as a sub-metering solution for commercial and industrial buildings.

5. Upgrade Path to Ethernet & Harmonics

For Modbus-TCP, harmonic analysis (up to 51st), and energy metering (kWh), upgrade to the ZH-40063-3 series. See ZH-40063-3 product page for details.
