Description

Emerson  1C31224G01  analog input module

Functional characteristics
Analog signal acquisition
It supports multiple standard analog signal inputs (such as 4-20mA current, 0-10V voltage, thermal resistance/thermocouple temperature signals), and can be adapted to the signal acquisition requirements of pressure, flow, temperature, liquid level and other sensors.
High-precision conversion
It is equipped with A built-in high-resolution A/D converter (usually 16 bits or more) to ensure the accuracy and stability of signal conversion and reduce measurement errors.

Multi-channel integration and isolation
Generally, 8/16 independent channels are integrated. Electrical isolation designs (such as optocoupler or transformer isolation) are adopted between each channel and from the system circuit to avoid interference between channels and the influence of external noise.
Signal Conditioning and Filtering
It has functions such as signal amplification, linearization processing, and anti-aliasing filtering, and can preprocess the input signal to improve data quality. Some models support disconnection detection and over-limit alarm.
Self-diagnosis and condition monitoring
The working status of each channel is displayed through LED indicator lights (such as normal signal, over-limit, and fault), supporting module self-diagnosis (such as abnormal power supply and A/D converter failure), and feeding back the diagnostic information to the DCS system.

Application scenarios
Process parameter monitoring
It is widely applied in industries such as power, chemical engineering, petroleum, and metallurgy, for collecting continuously changing process parameters such as boiler temperature, pipeline pressure, flow sensor signals, and storage tank liquid levels.
Closed-loop control system
Provide real-time feedback signals for the PID controller, participate in the closed-loop regulation of the system (such as temperature control and flow regulation), and ensure the stability of the production process.
Data acquisition and monitoring
As the front-end module of the SCADA (Data Acquisition and Monitoring) system, it converts the on-site analog signals into digital ones and transmits them to the main control system to achieve remote monitoring and trend analysis.
