Working Principle:
The module samples incoming analog voltage or current signals through a 16-bit ADC. On-board DSP computes power and energy metrics from the digitized waveforms. Results are transmitted over the RS-485 Modbus RTU link to the host controller, which can poll multiple modules on a shared bus.
Application Scenarios:
-
Power management and energy monitoring
-
Machinery health monitoring
-
Distributed Control Systems (DCS)
-
Process automation and control
-
Integration with PLCs and SCADA systems
Installation Requirements:
-
Mount on standard DIN rail within a control cabinet
-
Provide 24 V DC (±10%) auxiliary power
-
Terminate the RS-485 bus with proper bias and termination resistors
-
Observe polarity for 4–20 mA and 0–10 V DC field signals
Usage Notes:
-
Maintain operating temperature within –40 °C to +85 °C
-
Ensure correct Modbus slave addressing to avoid bus conflicts
-
Calibrate periodically to sustain ±0.05% accuracy
-
Use shielded cable for analog inputs in high-noise environments
