DSAI146  3BSE007949R1 RTD Input Module

The DSAI146 RTD input module is a specialized input module for receiving and processing RTD (thermal resistance)

signals. RTD, or thermal resistance temperature sensor, is a temperature measuring element based on thermal

resistance effect, which is widely used in various temperature measurement and control systems.

The main function of the DSAI146 RTD input module is to convert the analog signal generated by the RTD sensor into

a digital signal for further processing, display or control. Here are some of the key features and possible functions of the module:

Multi-channel input: The module may support input from multiple RTD sensors, allowing simultaneous monitoring of multiple temperature points.

Signal conditioning: The module may contain signal conditioning circuits that amplify, filter, and linearize the RTD signal to improve signal accuracy and stability.

High-precision measurement: The module may employ high-precision ADC (analog-to-digital converter) and calibration algorithms to achieve high-precision temperature measurement.

Temperature range: The module may support a wide temperature measurement range to suit the needs of different application scenarios.

Communication interface: The module usually has a communication interface with the host computer or other control systems,

such as RS-485, Ethernet, etc., in order to transmit the measurement data to the host computer in real time for further processing or monitoring.

Configuration and calibration: Modules may provide configuration and calibration functions, allowing users to set parameters, calibrate modules, or adjust measurement ranges according to actual needs.

Power Supply: Modules are typically powered by standard power supplies, such as 24V DC, and may have a low-power design to accommodate the needs of long operation.
