8-Channel R4DCB08 Board RS485 Temperature Sensor Module - Indoor Outdoor Temperature Measurement for PLC Paperless Recorder 6-24V

This RS485 sensor module is designed for precise temperature data acquisition in industrial and scientific applications. It supports MODBUS RTU instruction codes 03 and 06, enabling seamless integration compatible with paperless recorders and PLC systems. The module allows efficient temperature setting adjustments and reliable data transmissionConnect up to eight DS18B20 temperature sensors simultaneously for multi-point monitoring. Modify the 485 address to cascade up to 247 modules, ideal for large-scale temperature measurement networks. For setups exceeding 16 modules, use RS485 repeaters to ensure stable communicationAccurate temperature readings from -55℃ to +125℃ (-67°F to +257°F) with ±0.5℃ precision between -10℃ and 85℃. Suitable for indoor/outdoor environments including weather stations, server rooms, and warehouse monitoringSpecifications:Item Type: Sensor ModulePower Supply Voltage: 6-24VWorking Current: 8-13MA (related to the number of external sensor)Temperature measurement range: -55℃ to +125℃ (-67°F to +257°F).Accuracy:±0.5℃(When the temperature is between -10 ℃ and 85 ℃)Color: Blue+WhiteSize: 70 x 46 x 18MM(2.76 * 1.81 * 0.71in)Package List:1 x ModuleNote:1.
