Product Introduction:
The ABB AI845 3BSE023675R1 is an advanced analog input module designed for single or redundant applications in the S800 I/O system. This module offers a versatile solution with 8 channels, where each channel can either be configured for voltage or current inputs, depending on the MTU (Module Terminal Unit) used. It is equipped with advanced diagnostics, HART pass-through communication, and the ability to withstand overvoltage and undervoltage conditions.
Key Features:
- 8 channels for input signals (0…20 mA, 4…20 mA, 0…5 V, 1…5 V d.c.)
- Single-ended unipolar inputs
- Voltage and current inputs with a high input resistance for voltage inputs (>10 MΩ) and current inputs (250 Ω)
- Single or redundant operation mode
- 12-bit resolution for accurate measurements
- Current-limited transmitter supply per channel
- HART pass-through communication for compatibility with external transmitters
- Advanced on-board diagnostics to detect faults or errors
- 1 group of 8 channels isolated from ground
- Power supply for HART-compatible transmitters is supervised and current-limited
Applications:
The ABB AI845 module is ideal for applications where multiple analog sensors or transmitters are needed for precise measurements. It is commonly used in:
- Process control industries where analog data such as temperature, pressure, flow, and level are critical.
- Power plants, oil and gas, and chemical industries that require robust and reliable input solutions for automation systems.
- SCADA (Supervisory Control and Data Acquisition) systems for monitoring and control of industrial processes.
- Systems that require redundancy for improved reliability and uptime.
Advantages:
- Versatile Inputs: Supports both voltage and current inputs, offering flexibility for different sensor types.
