DIN Rail 1000V High-Isolation 6-Channel AC High Voltage Data Acquisition Module with Harmonics & Modbus RTU/TCP
Product Overview
This product is a 6-channel high-voltage AC acquisition module. It features six total measurement channels, configurable as 6 voltage channels, or 3 voltage plus 3 current channels for power-type measurement. Any combination of voltage and current loops is also supported. When using 3 voltage and 3 current inputs, it can function as a 3-channel single-phase power measurement device or a three-phase measurement device. It measures parameters including power, frequency, power factor, energy, harmonics, fundamental waves, and vector sum. The linear accuracy is exceptionally high, achieving a resolution of 0.01% (1 part in 10,000). It employs true RMS measurement, delivering high accuracy, excellent stability, and high communication rates. Fully isolated processing technology ensures strong anti-interference capability. Measured electrical parameters are transmitted via the TCP/IP network using the Modbus-TCP protocol, fully compatible with MODBUS protocols in various SCADA/HMI software or PLC devices.
Key features
1.Wide-range power supply options: 10-30V DC or 10-55V DC.
2.Measurement of 6 channels of total harmonic distortion, 1st-51st order harmonics, and harmonic RMS values; 3 channels of frequency measurement.
3.Network communication supports a customizable multi-master polling mode (where response telegrams distinguish their respective masters).
4.Communication baud rate and device address can be configured via software or hardware for ease of use.
5.Can be used as a single-phase or three-phase power measurement product, measuring single-phase power, single-phase energy, total power, and three-phase sequence.
6.Multiple operating status indicators: a red LED indicates normal operation, a green LED indicates communication activity.
7.Supports both Modbus-RTU and Modbus-TCP protocols, freely selectable via configuration.
8.Power supply input is isolated; each measurement input is independently isolated from one another. Any combination of voltage and current inputs is customizable, up to a total of 6 channels.
9.Wide terminal spacing of 15mm between channels; channel-to-channel isolation voltage exceeds 3000V.
