Bently Nevada 163179-02 Main Processor Board for 3500/61 Temperature Monitor (With Recorder Output)
Manufacturer Background: Bently Nevada (Baker Hughes GE) main CPU processor printed wiring assembly (PWA) dedicated to 3500/61 temperature monitoring main module; core logic board supporting RTD/thermocouple temperature signal acquisition, alarm logic judgment, rack backplane communication and recorder analog output; used for turbine, compressor, generator bearing temperature monitoring systems, fully compliant with API 670, CE, UL industrial safety standards.
Part Number Breakdown: 163179-02
- 163179 = Base PWA serial number for 3500/60 & 3500/61 temperature monitor main control board
- -02 = Revision variant 2, matching 3500/61 main module with built-in recorder analog output channels
- Contrast model: 163179-01 = Revision 1 for 3500/60 temperature monitor (no recorder output)
Product Type: Hot-swappable single-width rack plug-in main control processor board; integrates high-precision temperature signal sampling circuit, multi-stage alarm threshold logic, backplane bus communication interface, 4–20mA recorder analog output drive circuit; works with 3500/61 series RTD/TC input daughter I/O cards to realize full-channel temperature monitoring and analog signal external recording output.
Matching System Components: 3500 series 4/8/14-slot rack chassis; 3500/61 main module housing; supporting I/O daughter cards:133819-02 (non-isolated RTD/TC internal terminal),133827-02 (non-isolated external terminal),133835-02 (isolated TC internal terminal); 3500 rack configuration software, paperless recorder, DCS analog input modules.
Core Hardware Overview:
1. Core Processing Function: Multi-channel high-precision RTD (Pt100/Pt1000) and thermocouple (K/E/J/T type) signal linear sampling, real-time temperature value calculation, configurable Alert/Danger two-stage alarm logic, latch alarm state storage.
2. Dedicated Recorder Output Circuit (-02 exclusive feature): Built-in independent 4–20mA analog output channels, each temperature channel can map to isolated analog signal for connecting external recorders, DCS, chart recorders.
3. Rack Communication Interface: Dual redundant internal backplane bus communication with 3500 rack power supply and TDI module, upload temperature static data and alarm event records to System 1 diagnostic workstation.
4. Electrical Isolation Spec: All temperature input circuits 1kV galvanic isolation; recorder analog output ports 2kV isolation to eliminate ground loop interference; built-in multi-stage lightning surge suppression circuit.
5. Power Consumption: Rated 7W, powered by 3500 rack 24VDC backplane bus, no independent external power supply required.
6. Mechanical Spec: Standard single-width 3500 rack board size 241.3mm × 96mm × 26mm; net weight ~0.85kg; metal shielding housing, multi-layer EMI filter design for high-interference switchgear rooms.
7. Environmental Ratings: Operating temperature -30℃ ~ +65℃ inside cabinet; storage -40℃ ~ +85℃; relative humidity 5%–95% non-condensing; IEC 60068 vibration & shock certified for power plant and petrochemical substations.
8. Interchangeability: 163179-02 only compatible with 3500/61 recorder-type temperature monitor housing; cannot be interchanged with 163179-01 for 3500/60 non-recorder main module.
1. Product Overview
163179-02 is the dedicated main CPU control board for Bently Nevada 3500/61 temperature monitor module, the core processing unit of the entire temperature monitoring channel. Compared with 163179-01 for 3500/60, this revision adds independent built-in 4–20mA recorder analog output circuits, which is the key difference between 3500/61 and 3500/60 series temperature monitors.
It matches various RTD/thermocouple input daughter I/O cards to complete multi-point bearing temperature acquisition of turbines, compressors and generators, supports two-stage configurable alarm thresholds, and can output isolated analog signals synchronously to external recorders and DCS control systems for long-term temperature trend recording. Dual redundant backplane bus communication ensures stable upload of temperature data and alarm events to System 1 predictive maintenance software for fault trend analysis.
Adopts multi-layer metal shielding and multi-stage surge protection design, stable operation under strong electromagnetic interference environment of high-voltage switchgear rooms. Hot-swappable rack plug-in structure allows replacement without powering off the whole 3500 rack, temperature monitoring logic will not be interrupted during maintenance. Widely used in thermal power, petrochemical, cogeneration unit rotating equipment temperature protection cabinets requiring on-site analog recorder output.
