Description
Bently 3500/92‑136180‑04
Technical Specifications:
- Main function: Serial signal termination and transition for 3500/92 communication gateway
- Supported signal: RS232, RS422, RS485 serial communication signal
- Operating ambient temperature: ‑30°C ~ +65°C
- Storage temperature: ‑40°C ~ +85°C
- Matching object: 3500/92 series front‑side communication gateway module Functional Features:
- Provide screw‑locking field‑wiring terminal blocks for gateway serial communication signals
- Complete signal isolation transition between rack internal back‑plane signal and external field wiring 3.‑04 variant adopts exclusive terminal pin‑out definition for serial channels
- Built‑in signal filtering components to suppress industrial‑site electromagnetic interference
- Standard rear‑slot installation structure for 3500 rack, perfectly mate front‑side 3500/92 gateway module mechanically and electrically Application Scenarios: Rear supporting termination hardware for 3500/92 gateway in power plant, petrochemical plant rotating machinery protection rack; field serial communication wiring transition for gateway connecting DCS serial communication interface Performance Parameters: Reliable serial signal transmission path between front gateway module and external field cables; built‑in filter improves anti‑interference capacity for industrial heavy‑EMI environment Material Composition: Industrial metal mounting bracket, plastic housing; screw‑locking wiring terminal blocks; FR‑4 printed circuit board; signal‑filtering passive electronic components Structural Characteristics: Standard rear‑side plug‑in unit for 3500 rack rear‑side slot; inner‑side high‑density connector connects rack back‑plane bus; outer‑side exposed screw‑type wiring terminals for field cable access; fixed with rack rear‑side fastening hardware Working Principle: Serial communication signal output by front‑side 3500/92 gateway is delivered to this rear‑I/O module via rack back‑plane connector. Internal circuit completes signal filtering and routing, serial signals are guided out to external screw terminals. Field installation personnel connect external serial communication cable on rack rear‑side terminals, no need to touch front‑side plug‑in modules inside rack cabinet. Installation Requirements:
- Install module to corresponding rear‑side slot of 3500 rack, slot position must correspond with front‑side 3500/92 gateway module
- Tighten mounting screws to ensure reliable contact between module and rack back‑plane connector
- Field serial communication cable wiring must comply with‑04 variant official pin‑out document
- Communication cable shielding layer executes single‑point grounding as per engineering standard Usage Precautions:
- Never input high‑voltage signal to serial signal terminals, otherwise internal circuit will suffer permanent damage
- Regularly check terminal screw tightness, prevent bad contact under long‑time equipment vibration
- Install matching terminal resistor on RS485 bus when project requires
- Maintain good ventilation, dust‑proof and dry environment for rack cabinet
