Deterministic Modbus Communication and Firmware Integration
The internal processing engine executes real-time discrete Fourier transform (DFT) algorithms up to the 63rd harmonic order across three-phase voltage and current channels. Serial communication via the rear RS485 port operates deterministically under the Modbus RTU protocol, enabling direct registers polling by programmable logic controllers (PLCs) or supervisory control and data acquisition (SCADA) master nodes. Onboard firmware flash memory retains event logs, waveform captures, and user-configured alarm setpoints during primary power interruption without requiring external battery backup power.
Frequently Asked Questions
Q: What is the primary function of the four isolated analog outputs on the PQMII-T20 model?
A: The four isolated analog outputs convert internal calculated electrical parameters (such as phase voltage, current, active power, or total harmonic distortion) into configurable 4-20 mA DC signals for direct interface with legacy DCS or PLC analog input cards.
Q: How does the front RS232 port function relative to the rear RS485 port?
A: The front RS232 port provides a point-to-point connection for temporary laptop diagnostic access, parameter configuration, and firmware flash updating, while the rear RS485 port serves as the permanent multi-drop network interface for continuous system data acquisition.
Q: What power input range is supported by the auxiliary power terminal on this model?
A: The PQMII-T20 auxiliary power terminal accepts low-voltage control power operating between 20-60 VDC or 20-48 VAC at 50/60 Hz, drawing a maximum power load of 20 VA.
Field Installation Guidelines
- Mount the meter securely into the panel cutout using the manufacturer-provided mounting brackets to ensure proper flush alignment and mechanical stability.
- Connect the auxiliary power supply to the dedicated power terminals, verifying that the input voltage matches the 20-60 VDC or 20-48 VAC input rating before applying power.
- Terminate RS485 communication wires using twisted-shielded pair cable (120 ohm characteristic impedance). Connect the shield line to earth ground at one point only to prevent ground loops.
- Wire current transformer (CT) and voltage transformer (VT) secondary circuits directly to the terminal block, ensuring correct phase sequence and polarity orientation.
- Ensure 4-20 mA analog output wiring remains routed separately from high-voltage AC power cables in distinct conduit channels to limit electromagnetic interference.
