AT-25002 – 7-Channel RTD Module with Modbus TCP
The AT-25002 is a high-precision 7-channel RTD input module designed for accurate temperature measurement and monitoring over Modbus TCP networks. Supporting Pt100 and Pt1000 sensors, it provides flexible configuration options for 2-wire, 3-wire, and 4-wire connections, making it suitable for a wide range of industrial temperature sensing applications.
Engineered for reliability and accuracy, the AT-25002 offers a typical measurement range of –200°C to 850°C for Pt100 and –70°C to 550°C for Pt1000, with an impressive accuracy of ±0.5°C (0.05% of full scale). Its web-based configuration interface and Ethernet utility tool simplify setup, calibration, and diagnostics.
With features like a built-in watchdog timer, robust industrial enclosure, and energy-efficient operation, the AT-25002 ensures stable performance in demanding environments.
