The equipment adopts the industry-standard plug-in frame structure, and its size is fully compatible with the standard system frame of the 3300 series. It realizes electrical connection through the frame backplane, and the installation, disassembly, on-site parameter configuration, debugging, maintenance, and spare parts replacement are all very convenient. The on-site wiring is neat, and the wiring operation is simple and efficient. The entire machine is designed and produced strictly in accordance with industry standards related to electrical safety, electromagnetic compatibility, and mechanical protection. The enclosure has the ability to resist dust, oil stains, and slight mechanical collisions, and can be stably deployed in conventional industrial environments such as industrial cabinets, central control rooms, device control rooms, and on-site cabinets. The module is uniformly powered by the same series of dedicated power modules, and all electrical interfaces are standardized. It can be flexibly matched with various components such as 3300 series power modules, relay output modules, communication modules, and display modules. The system has strong compatibility, and the later function expansion and system modification are flexible and convenient.

Function and Positioning

This module is a multi-channel comprehensive monitoring unit. Each channel of the internal monitoring is electrically isolated from each other and works independently without interfering with each other. The front end of the equipment can be connected to sensing devices such as eddy current sensors to receive, amplify, multi-level filter, shape, and linear conversion of the original weak signals, accurately collect and calculate physical parameters such as vibration and displacement. The module supports on-site self-defined multi-level alarm thresholds, can distinguish different alarm levels such as warning and danger, and also has self-check identification functions for sensor faults, circuit breakers, and signal abnormalities. When the monitoring value exceeds the preset safety range or the sensing circuit fails, the module will immediately trigger the internal alarm logic and transmit alarm instructions to the rear relay module, interlock control system, etc. In addition, the module is equipped with standard analog output function, which can stably upload real-time monitoring data to DCS, PLC, data recorders, on-site display instruments, etc., to achieve real-time display, continuous storage, and historical traceability of data. The product is mainly applied in multi-point status monitoring of large and medium-sized rotating machinery, early fault warning, over-limit safety protection, and remote transmission of operation data, etc., to build a complete industrial operation safety management system.

Core Performance Parameters

The signal acquisition sensitivity of each channel of the module is high, the full-scale linearity performance is excellent, the repeat measurement accuracy is high, and the data drift during long-term operation is extremely low. The measurement results are accurate and reliable. The internal equipment is equipped with multiple filters and anti-interference circuits, which can effectively resist electromagnetic interference generated by large-power motors, frequency converters, and high-voltage power lines on-site, eliminating signal jumps, data distortion, and false alarms. The channel signal processing and response are fast, with extremely low transmission delay, and can provide real-time feedback of the equipment's dynamic operating state. The equipment supports uninterrupted continuous operation 24/7, with stable core circuits and components, no obvious performance attenuation under long-term load operation, and mechanical and electrical service life conforms to industrial-grade equipment standards. The insulation performance between channels and ground is good, the electrical isolation effect is reliable, effectively blocking signal crosstalk between circuits, improving the electrical safety of the entire system. The equipment operates within the temperature and humidity range of conventional industrial indoor and cabinet environments, has strong high and low temperature tolerance, and has a wide environmental adaptability range. The analog output signal is in a universal industrial standard format, has strong load capacity, can meet long-distance signal transmission requirements, the alarm circuit operates accurately, and has excellent anti-jitter performance. 

General Adaptable Accessories

The signal acquisition end can be used in conjunction with 3300 series eddy current probes, extension cables, preamplifiers, etc., to ensure the stability of the original signal acquisition and transmission. For on-site installation and wiring, basic auxiliary materials such as shielded signal cables, standard terminals, cable clamps, and waterproof connectors can be selected. This helps to standardize the layout of the lines and enhance the firmness and protection of the connections. In terms of system integration, the 3300 series standard racks and system power modules can be used. At the same time, it can be freely combined with relay output modules, communication interface modules, and other functional modules to flexibly build a complete monitoring system according to the on-site monitoring points, alarm logic, and data transmission requirements. The signal output terminals can be externally connected to sound and light alarm devices, intermediate relays, industrial control systems, data recording equipment, and unit safety interlock circuits, etc. The module interface terminals and common vulnerable components all adopt the 3300 series universal specifications, making spare parts procurement and replacement convenient. Daily inspections, parameter settings, function verification, and fault troubleshooting can be completed using conventional industrial electrical tools and accompanying configuration tools.

Applicable equipment fields

The product is widely used in industrial fields such as thermal power generation, petrochemicals, coal chemical industry, metallurgy, oil and gas extraction, heavy equipment manufacturing, etc. It is mainly applied in state monitoring systems of various large and medium-sized rotating mechanical equipment such as steam turbine generators, gas turbines, centrifugal compressors, large draft fans, smoke turbine, high-pressure large pump sets, heavy gear sets, etc. The equipment is mostly installed in the main control cabinet rooms of power plants, control rooms of chemical plants, metallurgical power rooms, on-site electrical cabinets of units, etc., undertaking tasks such as online monitoring of vibration and axial displacement at multiple points, fault warning, safety interlock protection, and remote data transmission, providing comprehensive safety protection for core power equipment of continuous production, ensuring the long-term safe, stable, and efficient operation of the units.
