ABB AI843 3BSE028925R1 Analog Input Module Consult Us
Product Overview
The ABB AI843 3BSE028925R1 Analog Input Module is a high-performance industrial automation device designed for thermocouple and millivolt (mV) signal measurement. It features 8 differential input channels, supporting various thermocouple types (B, C, E, J, K, L, N, R, S, T, U) and linear mV signals ranging from -30 mV to +75 mV. The module includes a dedicated Pt100 RTD channel for Cold Junction (CJ) compensation, ensuring high accuracy in thermocouple measurements. With its 16-bit resolution and strong anti-interference capability (CMRR 100 dB), the module is ideal for high-precision temperature measurement in complex industrial environments.
Key Features
- Multi-Channel Differential Input: 8 independent differential input channels for thermocouple and mV signal measurement.
- Dedicated CJ Compensation Channel: Includes a dedicated Pt100 RTD channel for CJ temperature measurement.
- High Resolution: 16-bit A/D conversion for precise signal acquisition.
- Redundancy Support: Supports single or redundant operation for enhanced system reliability.
- Wire-Break Detection: Open-circuit detection for input channels ensures system reliability.
- Flexible Configuration: Supports user-defined CJ temperature or CJ temperature from the application.
