I. Product Overview
This product is a real-time measuring 24 channels of dc voltage and current data acquisition module, 24 AD difference model acquisition for high precision measurement, points and 12 input current and dc voltage and 12 road signals measured by special measurement chip, accurate measurement of all kinds of dc signals, anti-interference performance is good, and high accuracy, good stability; It adopts standard RS-485 bus interface and Modbus-RTU protocol. Widely used in street lamp monitoring, production automation detection, LED lamp aging detection, etc. This product has the following characteristics:
Synchronous sampling of 24 channels is independent of each other AD, data collection and update of all channels is completed in 0.1 seconds;
High accuracy, using 24-bit AD sampling;
Good stability, measurement accuracy is not affected by ambient temperature;
Differential input voltage and current, input signals are not isolated from each other;
