ABB UAD155A0111 3BHE029110R0111

Description

• • Isolation: Channel-to-channel isolation (500 V AC, 1 minute); Channel-to-ground isolation (1500 V AC, 1 minute)
  • Response Time: ≤ 100 ms (90% of step input)
  • Communication Interface: Integrates with ABB’s PROFINET or Ethernet I/P protocols (via the parent DCS backplane) for data transmission to the controller
• Functional Features
  • High-Precision Signal Conversion: Utilizes advanced analog-to-digital (A/D) conversion technology to maintain ±0.1% FS accuracy, ensuring reliable capture of subtle changes in field signals (e.g., pressure, temperature, flow).
  • Multi-Channel Independence: 8 differential input channels operate independently, preventing cross-talk between signals and enabling simultaneous monitoring of multiple process parameters.
  • Robust Isolation: Channel-to-channel and channel-to-ground isolation eliminates ground loops and electromagnetic interference (EMI), protecting the module and connected DCS components from voltage spikes or surges.
  • Self-Diagnostic Capabilities: Embeds built-in diagnostic functions to detect faults such as open circuits, short circuits, or power supply anomalies. Fault information is transmitted to the DCS in real time for timely maintenance.
  • Wide Environmental Adaptability: Withstands extreme temperatures (-25°C to +70°C) and high humidity (up to 95% non-condensing), making it suitable for indoor and outdoor industrial installations.
  • Easy Integration: Designed for seamless compatibility with ABB AC 800M/AC 800XA DCS, supporting plug-and-play installation via the system backplane and configuration through ABB’s Control Builder M software.
• Application Scenarios
  • Process Industries: Used in oil and gas, petrochemical, and chemical plants to monitor analog parameters such as pipeline pressure, reactor temperature, chemical flow rate, and liquid level (via sensors like pressure transducers, RTDs, or flow meters).
  • Power Generation: Integrated into thermal power plants, nuclear power plants, or renewable energy (solar/wind) facilities to track steam pressure, turbine speed, generator temperature, and coolant flow, supporting safe and efficient power production.
  • Manufacturing: Applied in automotive, pharmaceutical, and food processing lines to monitor process variables like conveyor speed, mixing tank level, and heating system temperature, ensuring consistent product quality.
  • Water and Wastewater Treatment: Used to measure water flow rate, pH value, dissolved oxygen levels, and pump pressure in treatment plants, enabling automated control of filtration, disinfection, and distribution processes.
  • Mining and Metals: Deployed in mining operations and steel mills to monitor ore conveyor load, blast furnace temperature, and rolling mill pressure, supporting heavy-duty industrial process control and safety.
