+ 85°C, with a total measurement range of between -55 and +125°C. Up to 20 DS18B20 sensors can be connected to each port on the I-87004W module in a daisy-chain arrangement with a maximum wiring distance of 100 meters. The I-87004W module is fully RoHS compliant, and features 4 kV ESD protection as well as 3000 VDC intra-module isolation.
Chapter 2. Quick start I-87004W is a digital temperature sensor module that supports the DCON protocol. The host needs to use some DCON commands to configure and communicate with the I-87004W. ICP DAS provides the DCON Utility Pro program that can configure and test I-87004W without understanding any DCON command.

Step 3: Configure I-87004W using DCON Utility Pro To read temperature, each sensor must be assigned a channel index. The easiest way is to select Temperature tab and select “Assign all new sensor as default”. Then, you can read the temperature for all sensors.
Chapter 3. Using DS18B20 Temperature Sensor The I-87004W provides four ports and up to 20 DS18B20 sensors can be connected to each port. Each DS18B20 has a unique 64-bit serial code, which can be represented by 16 characters in hexadecimal format. The user must know the serial code of each...
