## Overview

The DAOKI DC 12V RS485 Modbus RTU module is a compact, high-accuracy industrial-grade voltage and current acquisition device. Supporting dual voltage ranges (0-5V & 0-10V) and current up to 20mA, it delivers ±1% measurement accuracy with fine resolution. Designed for scalability, it can network up to 247 modules simultaneously, making it ideal for advanced PLC and smart home automation systems.

## Description

Product description 4-channel voltage and current acquisition module: 1 Working voltage 8-24V 2 Working current: 10-15MA 3 MODBUS RTU instruction support 03 06 function code 4 V1 channel voltage measurement range is 0-5V, V2 channel voltage measurement range is 0-10V, C1/C2 channel current measurement range is 0-20MA 5 Voltage resolution is 0.01V, measurement accuracy is 1%; current resolution is 0.1MA, measurement accuracy is 1%; if the error is greater than 1%, it can be calibrated 6 In addition to the computer serial port super terminal input, MODBUS RTU commands can also be input by PLC 7 In MODBUS RTU command mode, it can support up to 247 devices to be used in parallel 8 Size: 45*30*15 9 Weight: 10 grams The package includes: 1 x Voltage Acquisition RS485 Module 1 x flat cable

Review: Nicely made, decent document on git - Bought one for evaluation. Works great, as decent git document describes (as noted by other reviewer, search for N4AIA04). Nicely labeled silkscreen. Input stage is voltage divider into opamp (Vadc = Vin * Ra/(Ra+Rb), where Ra,b = 100k, 39k for 0..5VDC input; Ra,b = 100k, 191k for 0..10VDC input). I needed to measure input voltage up to 20VDC, so added a 270k resistor between the input terminal and V1 0-5Vin terminal. Changed the scaling register from 1000 to 2940 so the output now read in 0.01V increments up to 20VDC. Current consumption is ca 10.0mA using its onboard linear regulator. Only negative is the mounting holes are very small (2mm screw), not more common/robust eg 4-40. Am ordering more for my application.
Review: Web search for documentation on N4AIA04 - Works great with ModBus Poll. desertcart page could include some kind of hint, like a link.
