Principle of Use
Signal acquisition and conversion: ABB SPASI23 receives the analog signal output by the sensor (such as 4-20mA current or 0-10V voltage) through 16 input channels, and uses a high-precision ADC (analog-to-digital converter) to convert the continuously changing analog quantity into a digital signal.
Signal conditioning: Built-in signal amplification, filtering and linearization processing functions to eliminate noise interference and improve signal stability.
Data transmission: ABB SPASI23 transmits data through RS-485 bus or Modbus The RTU protocol transmits digital signals to PLC, DCS or host computer system to achieve real-time monitoring and control.
Redundancy and expansion: supports multi-module cascading, distinguishes modules by address code, and expands the number of signal acquisition channels.
Functional Features
High precision and stability: ABB SPASI23 uses 16-bit ADC and isolation technology to ensure measurement accuracy (±0.1% typical value).
Anti-interference design: (such as filter circuit) is suitable for industrial scenarios with complex electromagnetic environments.
Flexible configuration and scalability: ABB SPASI23 supports multiple signal type inputs, and can configure input range, gain and other parameters through software to adapt to different sensor requirements.
