4-Channel Fully Isolated DC Combo Data Acquisition Module

4-Channel Fully Isolated DC Combo Data Acquisition Module

Product Overview
This product is a real-time measurement and acquisition module for comprehensive collection of electrical parameters of 4-channel DC loads. It uses high-speed isolation devices to achieve isolation between signals in each channel. The signal measurement adopts a dedicated 24 bit high-precision true RMS measurement chip to measure effective value parameters such as current, voltage, power, and accumulated electricity. It has high accuracy, good stability, and fast sampling speed; Standard Modbus RTU protocol or Modbus TCP protocol. Widely used in production automation testing, computer room monitoring, product aging detection, etc.
