Function and Positioning

This module is a multi-functional integrated monitoring unit, integrating multiple independent measurement channels. Each channel is electrically isolated from each other, and their operations do not interfere with each other. The main functions are divided into four sections: signal acquisition, data processing, alarm triggering, and signal output. The front end can connect to various industrial general sensors to collect physical quantities such as rotational mechanical vibration and axial displacement, converting the original weak signals into standard electrical signals. After multiple levels of filtering, shaping, and amplification processing, precise calculations are completed. The module supports on-site parameter configuration and can customize warning and danger threshold values. When the measured parameters exceed the set range, the sensor breaks wire, or the line is abnormal, the internal alarm logic is automatically triggered, and alarm instructions are sent to the relay module and the control system at the back end. At the same time, it is equipped with standard analog output functions, which can upload real-time monitoring data to industrial control systems such as DCS and PLC, enabling remote data viewing and centralized control. The module has a built-in hardware status self-check function, which can monitor the circuit, channels, power supply, and sensor circuit conditions in real time, and actively identifies abnormal states. The product is mainly applied to multi-point status monitoring, fault warning, over-limit protection, and data remote transmission scenarios of large rotating equipment such as steam turbine units and compressor units, building a comprehensive unit operation monitoring system.

Core Performance Parameters

The module has high signal acquisition sensitivity, excellent channel linearity, full-scale measurement error controlled within the standard range, good repeatability measurement stability, and can meet the requirements of high-precision industrial monitoring. The internal adopts a multi-level anti-interference circuit design, which can effectively shield electromagnetic interference generated by large-power motors, frequency converters, and high-voltage transmission lines, eliminating signal distortion, data jumps, and false alarms. Each channel has a fast response speed, and the signal transmission and processing delay is extremely low, enabling real-time feedback of equipment operation status. The module supports 7×24-hour uninterrupted continuous operation. Under long-term load conditions, the circuit components, acquisition unit performance do not show significant attenuation, and the mechanical and electrical service life meets the requirements of industrial site long-term service. The electrical insulation performance meets the standards, with reliable isolation between channels and between channels and ground, effectively blocking circuit crosstalk, and enhancing the electrical safety of the entire system. The working temperature and humidity are adapted to industrial cabinets and indoor conditions, and can operate stably within the conventional industrial temperature and humidity range. The environmental adaptability is outstanding. The analog output signal complies with industry general standards, has strong signal load capacity, and can be stably transmitted to the back-end control system over a long distance. The alarm circuit action is accurate, threshold switching is clear, and has strong anti-jitter ability. 

General Adaptable Accessories The on-site signal acquisition terminal can be used in conjunction with Bently series eddy current probes, vibration sensors, preamplifiers, high-frequency coaxial cables, signal shielded cables, etc., to ensure the quality of original signal acquisition and transmission. During wiring construction, standard terminal blocks, cable clamps, waterproof connectors, etc. can be used as basic auxiliary materials to standardize the layout of the lines and enhance the reliability of wiring. At the system integration level, dedicated to the 3300 series standard racks and system power modules can be used, which can be freely combined with relay output modules, communication interface modules, display modules of the same series, to complete the configuration of the entire system according to the on-site monitoring points, alarm logic, and data upload requirements. On the signal output side, external devices such as intermediate relays, audible and visual alarm devices, industrial PLCs, DCS control systems, recorders, etc. can be connected. The module interface terminals and internal common vulnerable components all adopt the 3300 series general specifications, and spare parts procurement and replacement are convenient. Daily inspections, parameter configuration, function verification, and fault troubleshooting can be completed using conventional industrial electrical tools and accompanying configuration tools.
