Description
Bently 3500/92‑136180‑03
Technical Specifications:
- Function: Serial signal termination transition for 3500/92 gateway
- Signal support: RS232, RS422, RS485 serial communication
- Operating temperature: ‑30°C ~ +65°C
- Storage temperature: ‑40°C ~ +85°C
- Matching equipment: 3500/92 series front‑side communication gateway module Functional Features:
- Offer screw‑type field‑wiring terminals for gateway serial communication signals
- Realize signal transition between rack internal back‑plane and external field cables 3.‑03 variant uses dedicated terminal pin‑out definition for serial channel
- Built‑in signal filtering components for restraining industrial electromagnetic interference
- Standard rear‑slot installation for 3500 rack, mechanical and electrical match front‑side gateway module Application Scenarios: Supporting rear termination hardware for 3500/92 gateway of turbine, compressor and generator machinery protection rack in petrochemical and power industry; field serial communication wiring transition for connecting gateway with DCS serial interface Performance Parameters: Stable serial signal transmission between front gateway module and external field cable; signal filtering improves anti‑interference ability under industrial electromagnetic environment Material Composition: Industrial mounting metal bracket and plastic housing; screw‑locking type wiring terminal blocks; FR‑4 printed circuit board; signal filtering passive components Structural Characteristics: Standard rear‑side plug‑in unit for 3500 rack rear‑slot; inner‑side high‑density connector connects rack back‑plane; outer‑side exposed screw terminals for field cable connection; fixed by rack rear‑side fasteners Working Principle: Serial communication signal generated by front‑side 3500/92 gateway is transmitted via rack back‑plane connector into this rear I/O module. After internal filtering and signal routing, serial signal is exported to external screw‑locking terminal blocks, construction workers can finish external serial cable wiring on rack rear‑side without opening front‑side of rack. Installation Requirements:
- Insert this rear‑I/O module into correct rear‑side slot of 3500 rack, keep slot position aligned with front‑side 3500/92 gateway module
- Fasten mounting screws to guarantee good contact between module and rack back‑plane connector
- Field serial communication cable wiring strictly follow‑03 variant terminal pin‑out table
- Communication cable shielding layer implement single‑point grounding according to engineering specification Usage Precautions:
- Strictly prohibit accessing high‑voltage signal to serial signal terminals to avoid circuit burnout
- Periodically inspect terminal screw tightening condition, prevent loose contact caused by equipment vibration
- Configure RS485 bus terminal resistor when needed
- Avoid corrosive gas and heavy dust accumulation inside rack cabinet
