ABB 311041 Product Description:
The ABB 311041 is an advanced circuit breaker designed for use in low-voltage distribution systems. It incorporates state-of-the-art electronic tripping technology, ensuring rapid and reliable protection against overloads, short circuits, and other electrical faults. With its adjustable tripping characteristics, the 311041 can be tailored to meet the specific requirements of various electrical loads.
The BENTLY CFP-AI-111 is an analog input module tailored for Condition Monitoring Systems (CMS) of rotating machinery, with parameters optimized for industrial-grade reliability and accuracy:
Core Module Specifications: 4 independent analog input channels, compatible with mainstream monitoring systems such as Bently Nevada 3500 and 1701, supporting “plug-and-play” cartridge-style installation.
Sensor Compatibility:
Passive Sensors: Supports Pt100/Pt1000 Resistance Temperature Detectors (RTDs, temperature range: -200°C to +850°C) and J/K/T/E/R/S/B-type thermocouples (temperature range: -270°C to +1768°C, depending on type).
Active Sensors: Supports 4–20mA current signals and 0–10V voltage signals (compatible with Bently Nevada 3300 XL vibration sensors, shaft position sensors, pressure sensors, etc.).
Measurement Accuracy:
RTD temperature accuracy: ±0.05°C; thermocouple temperature accuracy: ±0.1°C; 4–20mA/0–10V signal accuracy: ±0.02% of Full Scale Range (FSR)—ensuring even tiny changes in critical parameters like vibration and shaft position are accurately captured.
Sampling Rate: 100 samples per second per channel, enabling real-time recording of pulse-like vibrations caused by rotor imbalance.
Electrical Performance:
Power Supply: 24V DC (wide voltage range: 20–30V DC), maximum power consumption: 150mA.
Protection Design: Input channels feature short-circuit protection (withstands 50V DC) and Electrostatic Discharge (ESD) protection (complies with IEC 61000-4-2 Level 4). Optical isolation (2500V AC for 1 minute) is provided between inputs, data bus, and power supply to isolate external interference.
Environmental Adaptability:
Operating Temperature: 0°C to +60°C; Relative Humidity: 5%–95% (no condensation).
Protection Rating: IP20 (suitable for enclosed cabinet installation); Vibration Resistance: 5Hz (amplitude 0.15mm), meeting operational requirements of power plants, oil and gas platforms, etc.
Structure & Indicators: Dimensions: 160mm × 100mm × 25mm (fits Bently system cabinets). Each channel is equipped with “Channel Active” and “Channel Fault” LED indicators, with power and communication status displayed simultaneously for quick module status diagnosis.
