Function and Positioning

This module is a multi-channel integrated monitoring unit. The monitoring channels within the module achieve electrical isolation from each other, and each channel operates independently without interfering with each other. The front end of the equipment can be equipped with dedicated sensing devices such as eddy current sensors to receive, amplify, multi-level filter, waveform shaping, and linear conversion of the original weak sensing signals, accurately collecting key operating parameters such as rotational mechanical shaft vibration and axial displacement. The module supports on-site autonomous configuration of multiple alarm thresholds, can distinguish different alarm levels such as warning and danger, and has a complete loop self-check function, which can automatically identify 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 built-in alarm logic and transmit alarm instructions to the relay module, the unit interlock control system, and other terminals. At the same time, the equipment is equipped with standard analog output functions, which can stably upload real-time monitoring data to DCS, PLC, data recorders, on-site display instruments, etc., achieving real-time data display, long-term storage, and historical operation status traceability. This product is mainly applied in multi-point online monitoring of large and medium-sized rotating machinery, early fault warning, parameter over-limit protection, and remote transmission of operation data, building a complete industrial operation safety control system.

Core Performance Parameters

The signal acquisition sensitivity of each monitoring channel of the module is excellent, the full-scale linearity is good, the repeat measurement accuracy is high, and the data drift during long-term continuous operation is extremely low. The monitoring results are accurate and reliable. The module integrates multiple filtering and anti-interference circuits to effectively shield electromagnetic interference generated by large-power motors, frequency converters, and high-voltage power lines, avoiding signal jumps, data distortion, and false alarms. The signal processing and response speed of the channel are fast, the signal transmission delay is extremely small, and it can synchronously feedback the dynamic operating state of the equipment in real time. The equipment supports uninterrupted continuous operation 24/7, with stable core components and circuits, no significant performance degradation during long-term load operation, and mechanical and electrical lifespans meet the requirements for long-term operation in industrial sites. The channels between each other and the ground have reliable electrical insulation and isolation capabilities, effectively blocking signal interference between circuits, improving the electrical safety level of the entire system. The product works within the temperature and humidity range suitable for conventional industrial indoor and cabinet environments, has strong high and low temperature tolerance, and has a wide environmental adaptability range. The analog output adopts a universal industrial standard signal format, has strong load capacity, can meet long-distance signal transmission requirements, the alarm circuit operates accurately, and has outstanding anti-signal jitter ability. 

General Adaptable Accessories The signal acquisition end can be used in conjunction with 3300 series eddy current probes, signal extension cables, preamplifiers and other dedicated sensing components to ensure the stability and integrity 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 protective connectors can be selected to standardize the line layout and enhance the firmness of wiring and the on-site protection capability. At the system integration level, it needs to be used in conjunction with 3300 series standard racks and dedicated power modules, and can be freely combined with relay output modules, communication interface modules and other functional components. Combined with the on-site monitoring points, alarm logic, and data transmission requirements, an integrated monitoring system can be built. The module signal output end can be externally connected to audible and visual alarm devices, intermediate relays, industrial control systems, data recording equipment, and unit safety interlock circuits and other external devices. The module interface terminals and common vulnerable spare parts all adopt the 3300 series general specifications, and spare parts procurement and replacement are convenient. Daily inspection, parameter setting, function verification, and fault troubleshooting can be completed using conventional industrial electrical tools and accompanying configuration tools.
