Head mount Modbus RS-485 temperature transmitter

Main features

-Working with multiple TC/RTD inputs
-TC(K,E,S,B,J,T,R,N) RTD(PT100, Cu100, Cu50)
-Output: Modbus RS-485 RTU
-Power supply:12-35Vdc
-Accuracy: RTD 0.1% , TC 0.2%
-Working temperature: -30~80
-Storage temperature: -40~120
-Temperature drift: 50ppm/℃ F.S
-Load: less than 500 Ω
-Housing material: PA66
-Mounting screw: M4*2
-Range and input configurable via PC software
-Electrical isolation between input, output and source.
-Anti-surge, Anti-lighting strike, anti-reverse connection feature
-The transmitter is able to pick up the temperature from the temperature sensor and directly transmit the tempreature value to master device like PLC or HMI, for example, if you connect a type K sensor to the transmitter and the sensor is pointed to an object with 100 degree temperature, the HMI or PLC is able to receive the temperature reading directly from the transmitter, unlike 4-20mA temperature transmitter, the temperature from the sensor will have to be converted to 4-20mA signal and then transmitted to HMI and PLC, from the HMI and PLC, the 4-20mA analog signal will have to be converted to temperature reading so that the operator can check the temperature, for TT-510 transmitter, the temperature value is reflected directly to HMI or PLC without the A/D, D/A conversion involved. instead, it is transmitted via Modbus RS-485

TT-510      RS-485 Modbus RTU communication head mount temperature transmitter

Click on below link to download software and catalog

TT-510 is a hocky puck head mount temperature transmitter with RS-485 modbus RTU communication. below is a video tutorial on the communication demostration, we are using Modscan32 to simulate the master device to communication with the TT-510, below is the configuration on the Modscan 32

Address start at 0001(HEX)
Address length: 5
TT-510 address.: 1(you can change the address of the unit to other address with our software)
Modbus point type: Holding register

Modbus communication registery table as below. as you can see from the table, 0001 is for process value


parameter notation

parameter name

register address


Data Format



Value range





Process value


double byte




Unit 0.1℃



Check method


double byte



0 - no checksum

 1 - odd parity

 2 - even parity


no decimal point



Meter address






Instrument communication baud rate






Calibration password


double byte



0xA5A5 is valid


The password can only be calibrated after passing


below is a demo on the communication, you can see that the number of polls generate from the Modscan 32 and number of polls received from the transmitter, the first addres 0001 is for process value, we connect a type K sensor to the transmitter, at the begining of the video, the temperature reads at 33.7 celcius degree, moment later, we dip the temperature sensor into a couple of hot water.  the process value increase after that. you may see it on the video.

-Below is a video tutorial on how to use our PC configuration software for TT-510 head mounted RS-485 modbus temperature transmitter, you can change the address, communication baud rate and parity configuration from the software, the factory default of the setting as below

Address: 1
Baud rate: 9600
Parity: N

You can change address of the transmitter from 1 to 2, or any number from 1 to 254, and change the baud rate to 19200, and change the parity from N ot ODD or EVEN.
