Monitoring Made Simple: A Guide to the NT18B07 7-Channel Temperature Module
If you are looking to level up your automation or industrial monitoring, the NT18B07 7-Channel RS485 NTC Temperature Receiver
is a powerful little tool that often flies under the radar. Whether you’re managing a smart greenhouse or keeping an eye on server room vitals, this guide breaks down the essential manual details to get you up and running. What is the NT18B07?
The NT18B07 is a versatile data acquisition module designed to read up to seven temperature sensors simultaneously. It converts analog signals from NTC thermistors
into digital data that can be read over a serial connection using the industrial-standard Modbus RTU protocol Key Technical Specifications According to the official product documentation , here are the core specs you need for your setup: Operating Voltage: DC 6V to 24V (commonly powered by 12V or 24V systems). 7 independent NTC probe interfaces.
Modbus RTU (supports function codes 03 for reading and 06 for writing). Default Serial Settings: 9600 bps baud rate, No parity, 8 data bits, 1 stop bit. Approximately 1% when used with the recommended sensors. Crucial Setup Requirements
Before you start wiring, keep these manual "Notes" in mind to avoid common pitfalls: Sensor Type: The module specifically requires B3950 10K 1% NTC Thermistors
. Standard DS18B20 or other thermistor types will not provide accurate readings. Modbus Addressing: You can cascade up to 247 modules
on a single RS485 bus. However, if you plan on connecting more than 16, the manual recommends using an RS485 repeater to maintain signal integrity. Communication: To interface with a PC, you will need a USB to RS485 converter Quick Register Map Reference nt18b07 manual
When programming your PLC or Home Assistant setup, these are the primary registers you'll interact with: 0x0000 to 0x0006:
These hold the temperature values for Channels 1 through 7. The data is returned in 0.1°C increments (e.g., a value of equals 21.9°C). Used to read or write the RS485 Slave ID (Station Address). Used to set the baud rate. Conclusion
The NT18B07 is a robust, "set-it-and-forget-it" solution for multi-point temperature monitoring. By following the Scribd Protocol Guide
and ensuring your sensors match the B3950 spec, you can build a reliable monitoring network for everything from aquariums to industrial equipment. Need help with the Modbus commands for your specific setup?
is a 7-channel NTC thermistor temperature acquisition module designed for remote monitoring via the Modbus RTU
protocol. This industrial-grade board allows users to connect up to seven sensors simultaneously, providing a compact and scalable solution for greenhouse control, equipment monitoring, and aquarium management. Core Technical Specifications
The module is built for versatility in power and integration: Operating Voltage: DC 6V–24V (compatible with 9V, 12V, or 24V systems). Power Consumption: Extremely low operating current ranging from 8mA to 15mA Supported Sensors: Specifically designed for B3950 10K 1% NTC thermistors Measurement Range:
-20°C to +125°C, with an accuracy of approximately 1% when used with recommended sensors. Form Factor: Compact dimensions of 60 x 37 x 14mm Communication Protocol (Modbus RTU)
The NT18B07 functions as a slave device on an RS485 network. Default Settings: Baud rate of , 8 data bits, 1 stop bit, and no parity (N, 8, 1). Addressability: Supports cascading up to 247 modules on a single network by modifying the RS485 address. Function Codes: Utilizes standard Modbus function codes (Read Holding Registers) and (Write Single Register). Register Map: Registers 0–6:
Contain temperature readings for channels 1 through 7, provided in 0.1°C increments Register 254 (0x00FE): Stores the Modbus Slave ID (Default is 1). Read the Docs Setup and Integration Hardware Connection: Probes are connected via
interfaces. Use the "A+", "B-", and "GND" terminals for RS485 communication. Addressing: When cascading more than 16 modules, an RS485 repeater is recommended to maintain signal integrity. Data Interpretation:
Temperature data is returned as two bytes (High-bit first). To get the actual temperature, convert the hex value to decimal and divide by 10. Software Support: The device is supported by the Sming IOControl Library for easier coding and is often integrated into Home Assistant for smart home setups.
