• Maintenance feature: Hot pluggable, no need to power down the rack for replacement

2. Key Technical Features

2.1 Hardware configuration definition

• Supports hardware selection of mainstream thermal resistance types such as Pt100, Pt1000, copper resistance and nickel resistance;

• Compatible with 2-wire, 3-wire and 4-wire field wiring modes, and enables automatic lead resistance compensation for 3-wire RTD circuits;

• Predefines channel burnout detection direction, over-range judgment threshold and safety fallback value logic when the sensor is disconnected.

2.2 Engineering convenience

• After plugging in the personality module, the main RTD module automatically identifies configuration parameters upon power-on, without modifying firmware or re-downloading control logic;

• Standard FRU field replaceable unit structure, quick on-site replacement during maintenance or measurement point reconstruction;

• Universal interchangeability of same-type modules, lowering the spare parts management cost for process enterprises.

2.3 Environmental and reliability indicators

• Operating temperature: 0℃ ~ +60℃

• Storage temperature: -40℃ ~ +85℃

• Relative humidity: 5%–95% RH, non-condensing

• Conforms to industrial EMC anti-interference standards, shock and vibration resistant, suitable for long-term continuous operation inside control cabinets.
