PT-100 temperature to modbus RS485

• Temperature and PT100 resistance values can be read, multi‑functional.
• Up to 247 modules can be cascaded by modifying the 485 address (for more than 16 modules, use R485 Repeaters).
• High quality plastic material manufacturing ensuring maximum durability.
• Temperature measurement range: A version ‑20℃ to +400℃; B Version: ‑20℃ to +220℃. It is recommended to select a small scale version within the measurement range.
• Temperature measurement accuracy is 1%, if the temperature deviation is too large, please recalibrate.
