2. Core Functional Description
2.1 Whole Rack Central Configuration Management
The TDIX processor board undertakes centralized configuration storage and parameter management for all functional modules inserted inside 3500 rack. All configuration parameters including channel measurement type, pre-alarm and trip threshold, sensor sensitivity calibration data and 4–20mA analog output scaling set via official 3500 configuration software are solidified into onboard non-volatile flash memory on 134652-02, avoiding configuration data loss caused by instantaneous power failure or short-time power off of rack power supply. The module transmits configuration commands issued from front-panel USB port of 3500/22M to each monitoring card through rack internal backplane bus and feeds back real-time module running status for online configuration verification and modification.
2.2 Transient Dynamic Vibration Data Capture & Preprocessing
As core transient data processing carrier of TDIX unit, 134652-02 continuously collects high-speed raw dynamic waveform data from vibration, displacement, speed monitoring modules such as 3500/42, 3500/45 and 3500/50 via backplane bus, completes real-time digital filtering, FFT spectrum conversion and transient waveform screening inside onboard high-speed processor. It automatically locks and stores abnormal full-spectrum waveform and time-domain vibration data once equipment vibration exceeds preset alarm setpoints, realizing fault transient data snapshot for post-failure equipment failure analysis and troubleshooting, which is core foundation for off-line precision diagnosis of rotating machinery faults like rotor unbalance, misalignment and bearing damage.
2.3 Multi-Protocol External Communication Gateway
The module cooperates with front 3500/22M Ethernet interface to build multi-channel communication channel between whole 3500 rack and external upper systems. It supports standard 10/100Mbps Ethernet communication for data interaction with Bently System 1 online condition monitoring software platform, meanwhile compatible with Modbus TCP and RS485 Modbus RTU auxiliary protocol to transmit real-time measurement value, alarm status and equipment running parameters to plant DCS, PLC and third-party centralized monitoring system. Onboard communication isolation circuit effectively isolates rack internal signal and external field bus loop to prevent external surge interference from impacting whole rack measuring precision and protection logic stability.
2.4 Comprehensive Built-in Self-Diagnosis Function
Embedded full-range self-check circuit continuously monitors backplane bus communication state, onboard power supply voltage abnormality, internal memory fault and communication channel failure of each front monitoring module; once abnormal condition is detected, corresponding fault codes and fault location information will be stored in local memory and uploaded to front panel status indicator and upper monitoring system synchronously. It also monitors power supply fluctuation of rack backplane and provides early warning prompt when input voltage deviates beyond rated scope, helping maintenance personnel rapidly locate rack power supply hidden danger and circuit abnormal points.
3. Mechanical & Outline Specifications
134652-02 follows unified rear I/O card dimension standard of 3500 series rack, matched with single-width 3500/22M front module mechanical size; gold-plated edge connector is adopted on board edge to match 3500/05 rack backplane slot, ensuring stable power access and high-speed bus data transmission after long-term cabinet vibration from adjacent operating large rotating equipment. The circuit board is fixed with locking fastener matched with rack rear installation structure, overall net weight is about 0.52kg, and all component layout strictly follows industrial anti-vibration design standard to adapt long-term vibration environment of industrial site control cabinet.
4. Electrical Technical Parameters
All working power of this processor module is obtained from 3500 rack backplane with rated input DC voltage 24VDC ±10%, typical average power consumption under full-load normal working condition is less than 3.2W. Internal high-speed bus data transmission rate reaches standard TDIX dedicated bus specification to satisfy high-frequency transient waveform synchronous collection requirement of multi-channel monitoring modules inside rack; all signal input and communication circuits add ESD protection and lightning surge suppression components to restrain transient overvoltage damage caused by field miswiring and electromagnetic interference of surrounding high-current power cables.
5. Environmental Operating Conditions
Rated continuous working ambient temperature range is -30℃ ~ +65℃, short-time intermittent peak working temperature up to +70℃ will not cause permanent damage to internal electronic components; spare part storage temperature covers -40℃ ~ +85℃, requiring sealed dry storage away from acid-base corrosive gas and violent mechanical collision. Applicable working relative humidity is 5%RH~95RH under non-condensing environment, suitable for high-dust, high-humidity and slight oil mist industrial cabinet operating environment of thermal power, petrochemical, coal chemical and offshore oil-gas industry, complying with API670 international machinery protection standard and CE EMC industrial anti-interference certification specification.
6. Model Version Difference & Matching Rule
134652-02 is upgraded revision of base model 134652-01 TDIX rear processor board, with optimized arithmetic chip and communication peripheral circuit to promote transient data processing efficiency and long-term running stability; these two versions cannot be randomly cross-replaced during on-site maintenance without official factory configuration confirmation. It must be paired with corresponding 3500/22M front TDI panel of matching version, mismatched front and rear combination will result in abnormal rack communication and failure of transient data collection function; this module belongs to non-intrinsically safe standard type, cannot be directly applied to explosive hazardous area cabinet without matching safety barrier accessories.
