GE IS220PRTDH1A RTD Input Module

product description：

The GE IS220PRTDH1A RTD input module is an RTD (Resistance Temperature Detector) input module produced by General Electric (GE). It is specifically designed for high-precision temperature measurement and control in industrial environments. Here is a detailed introduction about this module:
I. Product Features
High Precision Measurement: The measurement accuracy reaches ±0.1℃, enabling accurate measurement of the temperature value of RTD.
Wide Range: Capable of measuring various RTD resistance ranges, with the input range ranging from -200°C to +800°C, meeting different application requirements.
Support for Multiple Input Types: Supports various RTD types such as Pt100, platinum 500, and Cu100, facilitating connection with various RTD sensors.
Cold Junction Compensation: Can automatically compensate for the influence of cold junction temperature changes, improving measurement accuracy.
Fault Detection: Can detect faults such as RTD open circuit and short circuit, ensuring safe operation of the system.
Electrical Isolation: High electrical isolation design is provided between channels and between channels and the backplane (such as 2500V AC isolation), combined with industrial-grade anti-electromagnetic interference circuits, can effectively resist on-site electromagnetic radiation and surge impacts, ensuring the stability of signal acquisition.
High Sampling Rate: Each channel can achieve a sampling rate of up to 100Hz, enabling rapid capture of temperature sudden change signals, providing timely data support for the emergency response of the control system.
Diagnostic Function: Equipped with a complete channel fault self-diagnosis function, capable of real-time monitoring of channel status and sensor operating conditions, with accurate and timely fault alarms.
