Description
Bently 3500/92‑136180‑02
Technical Specifications:
- Function: Serial signal termination and signal conversion for 3500/92 gateway
- Signal type: RS232, RS422, RS485 serial communication signal
- Working temperature: ‑30°C ~ +65°C
- Storage temperature: ‑40°C ~ +85°C
- Matching object: 3500/92 series front‑side communication gateway plug‑in card Functional Features:
- Provide field‑wiring terminal blocks for gateway serial communication signals
- Realize physical isolation transition between rack internal back‑plane bus and external site wiring
- Corresponding‑02 variant defines specific terminal pin‑out assignment for serial channel
- With anti‑interference filtering components for serial signal circuit
- Standard rear‑slot installation for 3500 rack, directly mates with front‑side 3500/92 gateway module Application Scenarios: Supporting rear‑hardware for 3500/92 communication gateway in power, petrochemical rotating machinery protection rack; on‑site serial communication wiring transition between gateway and DCS system serial interfaceBaker Hugh… Performance Parameters: Reliable signal transmission between front gateway and external field cable; built‑in signal filtering to restrain industrial site electromagnetic interference Material Composition: Housing: Industrial plastic and metal bracket; terminal block: Screw‑locking industrial wiring terminal; circuit board: FR‑4 PCB; filtering components for signal circuit Structural Characteristics: Standard rear‑side plug‑in module for 3500 rack rear slot; front‑side high‑density connector mates with rack back‑plane; outer side exposed screw‑type wiring terminal blocks for field cable connection; fixed with rack rear‑side mounting hardware Working Principle: The serial communication signal of front‑side 3500/92 gateway transmits through rack back‑plane connector to this rear I/O module. Internal circuit accomplishes signal filtering and signal routing, leads out serial signal to external screw terminal blocks, so field construction personnel can connect external serial communication cable on rear‑side terminals without touching front‑side gateway module inside rack。 Installation Requirements:
- Install this rear I/O module into corresponding rear slot of 3500 rack, correspond slot position with front‑side 3500/92 gateway module
- Tighten module fixing screws, ensure reliable contact between module and rack back‑plane connector
- Field serial communication cable connect to corresponding terminal according to‑02 variant pin‑out definition
- Shield layer of field communication cable shall implement single‑point grounding as per specification Usage Precautions:
- Do not access high‑voltage signal into serial signal terminals, will burn internal circuit
- Check terminal screw tightening torque regularly to prevent poor contact caused by equipment vibration
- RS485 bus must install terminal resistor according to project requirement
- Keep rack cabinet dry and dust‑proof environment
