Yokogawa AAI143-S00 Analog Input Module
- Product Introduction: It is a 16 – channel analog input module designed for Yokogawa’s CENTUM VP distributed control system. It is used to collect 4-20mA DC analog signals from field instruments, convert them into digital signals for processing by the DCS controller, and is suitable for large – scale data acquisition in industrial processes.
- Technical Specifications:
- Number of Channels: 16 isolated channels.
- Input Signal: 4-20mA DC.
- Accuracy: ±0.05% of full scale.
- Sampling Rate: 10 samples per second per channel.
- Working Voltage: 24V DC, power consumption ≤ 300mA.
Detailed content
-
- Isolation: 500V AC between channels, 1.5kV AC between input and system.
- Working Temperature: -20~70°C.
- Functional Characteristics:
- Channel isolation: Prevents signal crosstalk and improves measurement accuracy and system reliability.
- Hot – swap capability: Allows online replacement of the module without system shutdown.
- Diagnostic functions: Monitors channel status, open circuit and short – circuit faults with alarm indication.
- High – speed data transmission: Transmits collected data to the controller quickly to ensure real – time process control.
- Easy configuration: Supports online parameter setting via the DCS engineering tool.
- Application Scenarios: Widely used in petroleum, chemical, power generation, metallurgy and other industries. It is used to collect signals from pressure, temperature, flow and liquid level transmitters in the production process, and provides real – time data for the DCS system to implement control strategies and safety interlocks.
