Feature: 1. The module can be used with our temperature sensor with temperature measurement range from ‑20°C to 125°C and the accuracy up to 1%. 2. The power supply voltage of the module is 6-24V and the working current is 8-15MA. 3. High quality material can make sure the durability and stability of the module. 4. By modifying the 485 address, up to 247 modules can be cascaded for use, which is quite practical. 5. With professional design and reasonable structure, the module is easy to replace and install. Specification: Item Type: Module1. Function Description: Power Supply Voltage: 6-24V Working Current: 8-15MA (related to the number of external NTC) By modifying the 485 address, up to 247 modules can be cascaded for use (if more than 16, please use R485 repeaters) Adapted Sensor: B3950 10K 1% NTC thermistor, up to 7 NTC sensors can be connected at the same time Temperature Measurement Range (using our NTC sensor): -20℃ to +125℃ Temperature Measurement Accuracy (using our NTC sensor): 1% NTC Sensor Specifications: (NTC Sensor is not included) Item Type: 5x25mm Waterproof Probe Total Length: Approx. 50cm / 19.7in Resistance Value: 10K Resistance Accuracy: ±1% Resistance B Value: 3950±1% Temperature Measurement Range: -20℃-125℃ Wire Specification: 2651 26# Parallel wire temperature resistance 105℃ Plug Model: XH2.54-2P Probe: A version without mounting holes, B version with mounting holes (4MM/M4) . Package List: 1 x Module Note: 1 This module does not have NTC sensor, NTC sensor needs to be purchased separately (specification B3950 10K 1%). The resistance measurement accuracy of the module is 1%, and the theoretical temperature measurement range is ‑273‑200℃; the final temperature measurement accuracy and temperature measurement range are determined by the NTC thermistor. 2 Must use the correct sensor (B3950 10K 1% NTC), otherwise the temperature will not be accurate.
