Description
Bently 3500/72M | Part Number:140482‑01
Technical Specifications:
- Signal Channel Quantity:4 channels
- Matching Main Module:3500/72M rod‑position monitor
- Supported Transducer: Bently 3300‑series eddy‑current proximity probe system
- Operating Temperature:0°C ~ +60°C
- Storage Temperature:‑40°C ~ +85°C Functional Features:
- Realizes external termination for four‑channel eddy‑current probe signals
- Signal transmission path between field transducer and 3500/72M main module
- Transient over‑voltage protection circuit integrated inside assembly
- Field wiring is completed outside rack, convenient for maintenance and troubleshooting without pulling out rack module Application Scenarios:
- Reciprocating compressor monitoring project requiring external termination wiring layout, widely used in oil refinery, natural gas station, petrochemical plant Material Composition:
- Circuit Substrate: FR‑4 fire‑retardant PCB
- Inter‑board Connector: Gold‑plated connector connecting to 3500/72M main module
- Signal Interface: External cable interface for connecting to remote external termination block Structural Characteristics:
- Rear‑mounted plug‑in sub‑assembly for 3500/72M main monitor module
- Equipped with external cable interface for connecting to off‑rack termination block
- Inter‑board connector mates directly with main module circuit board Working Principle: Proximity probe signals are connected to remote external termination block, then transmitted via special cable to 140482‑01 I/O assembly. This assembly transmits transducer signals to 3500/72M main monitor module through inter‑board connector. Built‑in protection components suppress field‑side surge interference. Installation Requirements:
- Install 140482‑01 I/O assembly to rear side of 3500/72M main module before inserting whole module into rack
- Power‑off rack power during installation
- Use specified Bently signal cable connecting I/O assembly and external termination block
- Tighten all terminal screws with correct torque Usage Notes:
- Keep external termination block away from high‑voltage power cable
- Inspect cable connection status periodically
- Prevent moisture and dust polluting external termination block terminals
