PTA9B01 FAQ
Q: Dear I am currently using the PTA9B01 PT100 RS485 sensor module and have a specific question regarding the jumper settings labeled A, B, C, and D on the PCB. While I have reviewed the available documentation and the Modbus RTU protocol guide, I could not find any reference or explanation regarding the purpose or configuration of these jumpers. Could you please clarify the following: What are the functions of the jumpers A, B, C, and D? Are they related to sensor configuration (e.g., 2-wire or 3-wire PT100) or other operational parameters? Are there specific settings required for proper operation under certain conditions? Your guidance would be greatly appreciated, as it will help me optimize the use of this module in my application. If possible, could you also provide any additional documentation or examples related to these jumper settings? Thank you for your support. I look forward to your response. Best regards, A: Dear friend, the ABCD jumpers are for expansion and currently have no function. 2-wire and 3-wire are distinguished by wiring. You can refer to the wiring diagram in the manual. Q: Subject: Inquiry About Calibration Methods for PTA9B01 (Single-Point or Two-Point Calibration) Dear I am currently using the PTA9B01 PT100 RS485 module and have a question regarding the calibration process. Specifically, I would like to understand how to achieve accurate temperature readings and whether the module supports a two-point calibration method. Typically, calibration involves using: ...
