Nt18b07 Manual - [new]

The NT18B07 module acts as an interface between B3950 10K NTC sensors and a master device (such as a PLC, SCADA system, or microcontroller) using the Modbus RTU protocol. Key Specifications

💡 Keep the magazine clean of sawdust to prevent feeding issues.

Supports up to 247 modules via A0-A5 modification (default address depends on model).

For more details on the Modbus mapping, see the Scribd NT18B07 Guide .

: Connect to the RS485 Data- line of your USB-to-RS485 adapter or PLC master. 2. NTC Thermistor Input Terminals nt18b07 manual

The NT18B07 relies on precise Modbus register parsing to exchange data with a host master controller. It explicitly implements two fundamental Modbus function codes: Read Holding/Input Registers. Function Code 06 : Write Single Holding Register. Register Address Architecture

The primary takeaway for seamless integration is to first test the module alone on a PC with Modbus polling software to confirm basic functionality and its default address before moving to a final system—saving significant time during complex builds.

The is a 7-channel RS485 NTC thermistor temperature acquisition module commonly used for industrial monitoring and data logging. The NT18B07 module acts as an interface between

This indicates a wiring error on the load side. The relay acts only as a dry switch (like a light switch); it does not provide power out of the COM and NO pins on its own. You must feed external voltage into the COM terminal.

: ultra-low draw of 8–15 mA (fluctuates slightly based on the number of actively polled channels).

Note: Some NT18B07 units are "Code Search" compatible. In that case, follow your universal remote's auto-search manual.

Always remove the 18V Li-ion battery before clearing a jam or performing maintenance. Eye Protection: Wear ANSI Z87.1-rated safety glasses.

12V DC (Standard variant) or 110V–220V AC (Direct-line variant). Check your specific board markings before applying power.

: Connect each individual two-wire B3950 thermistor between a channel terminal ( CH1 through CH7 ) and its adjacent shared ground ( GND ) pin. NTC thermistors are non-polarized; orientation of the two wires does not matter. Modbus RTU Protocol and Register Maps
