Yokogawa AAI143-S50/A4S10 Precision Analog Input Module
The Yokogawa AAI143-S50/A4S10 represents a precision-engineered 16-channel analog input module designed for demanding industrial automation environments. This isolated 4-20 mA current input module integrates advanced surge protection circuitry, ensuring reliable signal acquisition in electrically harsh conditions.
Technical Specifications
- 16 isolated analog input channels
- 4-20 mA current input range
- Built-in surge absorber for enhanced protection
- High-precision signal conversion with ±0.1% accuracy
- Compact DIN rail mountable design
- Operating temperature: -10°C to +55°C
- Input isolation: 500V DC between channels
- Response time: <100ms per channel
Application Scenarios
This module excels in process control systems requiring multi-point current signal monitoring, including chemical processing plants, oil and gas facilities, water treatment systems, and power generation stations. The isolated architecture prevents ground loop interference, making it ideal for distributed control systems (DCS) and supervisory control and data acquisition (SCADA) applications where signal integrity is paramount.
Solution Benefits
Engineers deploying the AAI143-S50/A4S10 gain simultaneous monitoring of multiple 4-20 mA transmitters with individual channel isolation, reducing installation complexity and improving system reliability. The integrated surge protection minimizes downtime from electrical transients, while the standardized form factor ensures seamless integration with existing Yokogawa control platforms and third-party systems.
