Main functions and characteristics of 3500/53:
Overspeed protection: specifically designed for mechanical overspeed protection, aimed at driving alarms by continuously comparing the current machine speed with the configured alarm set point, achieving machine protection.
Quick response: The system provides a quick response function to ensure a quick response in the event of an overspeed event.
Redundant design: This module can form a 2 out of 2 or 3 out of 2 (recommended) voting system, improving the reliability and security of the system.
Multiple sensor support: suitable for Bently Nevada 3300 8mm eddy current sensors, 3300 16mm high-temperature eddy current sensors (HTPS), 7200 5mm, 8mm, 11mm, and 14mm eddy current sensors, 3300 RAM eddy current sensors, or magnetic sensors.
3500/53 Technical Specifications:
Input signal: Each overspeed detection module receives a signal from an eddy current sensor or magnetic sensor, with an input signal range of+10.0V to -24.0V. The signal exceeds this range and is restricted within the module.
Input impedance: 20k Ω.
Power consumption: Typically 8.0W.
Alarm Setpoint: For speed, it can be set below or above the alarm level (set point). In addition, dangerous (overspeed) setting points can be set for the rotational speed. All alarm setpoints are set by software configuration.
Alarm time delay: less than 30ms when the frequency is above 300Hz.
3500/53 System Configuration and Installation:
Installation requirements: The 3500 rack for installing the overspeed detection system requires redundant power supply.
Module location: The 3500/53 module can be installed in any slot (2-15) on the right side of the frame interface module, but the three module groups must be installed adjacent.
Configuration software: Use the 3500 rack configuration software to set alarm setpoints.
3500/53 application scenarios:
Industrial field: This module is widely used in key equipment monitoring in industries such as petrochemicals, power, steel, and papermaking, especially in situations where high-precision and high reliability overspeed protection is required.
Safety protection: Provide important machine speed information to operators and maintenance personnel, help identify potential problems in a timely manner, and take corresponding measures to ensure the safe operation of the equipment.
