Bently 3500-91 161204-01老款 EGD Communication Gateway Module (Old Revision, non‑M version)

Description

Hardware & Electrical Specifications

‑ Manufacturer: Bently Nevada (Baker Hughes) ‑ Compatible System: 3500‑05 full‑size / mini rack, mandatory pairing with 3500/22M TDI module ‑ Functional Type: Old‑Version EGD Ethernet Global Data Communication Gateway Module ‑ Communication Interfaces:  ‑ Ethernet: 10/100 BASE‑TX copper or 100BASE‑FX fiber (determined by matched rear I/O card)  ‑ Serial: RS232 / RS422 / RS485 on rear I/O ‑ Supported Protocols: EGD, Bently proprietary protocol, Modbus‑TCP, Modbus‑RTU ‑ Max quantity per rack: 1 piece only ‑ Typical power consumption:7.4 W, powered by rack backplane bus ‑ Front‑panel Indicators: OK LED, TX/RX LED ‑ Matching Parts: Main‑board 161204‑01 must pair with rear I/O:161216‑01 (copper) or 161224‑01 (fiber), sold separately ‑ Hot‑swap: Supports hot‑swap; communication data transmission interrupted during replacement; all machinery‑protection monitor modules keep normal protection operation. ‑ PCB Coating: Conformal coated for harsh industrial cabinet environment ‑ Safety Certification: CE, CSA hazardous‑area approvals available

Environmental Specifications

‑ Operating Temperature:‑30 ℃ ~ +65 ℃ ‑ Storage Temperature:‑40 ℃ ~ +85 ℃ ‑ Relative Humidity:5%‑95 % non‑condensing ‑ Vibration & Shock: Complies with API‑670 machinery‑protection cabinet standards

Mechanical Data

‑ Dimension(W×H×D):241.3 mm ×24.4 mm ×241.8 mm ‑ Weight: approx 0.79 kg

Core Functions

1. EGD high‑speed data gateway: Real‑time bidirectional data exchange with GE Mark VIe turbine control system, main original application scenario for this old‑version 3500/91.
2. Multi‑protocol data output: Upload vibration, position, speed, temperature, alarm events, rack fault status to DCS, historian, System‑1 diagnostic software via Modbus‑TCP / Modbus‑RTU.
3. Remote rack configuration: Support 3500 Rack Configuration Software online connect, download/upload rack project parameters through Ethernet port.
4. Protection‑safety isolation: Gateway hardware failure does not impact hardware trip logic of all protection monitor modules in rack; machinery‑protection function remains intact.
5. Self‑diagnosis: Detect backplane communication fault, Ethernet link fault, serial‑port fault; report module hardware fault to rack‑system log.

Installation, Replacement & Critical Warnings

1. Supports hot‑swap; data communication service is interrupted during plug‑pull, but machinery‑protection trip function is unaffected.
2. Compatibility warning: ‑ Two rear‑I/O variants: copper 161216‑01 or fiber‑optic 161224‑01; select according to field network layout. ‑ Old‑revision 161204‑01 (3500/91) cannot swap main‑board or rear‑I/O with upgraded 3500/91M. ‑ Only one 3500/91 can be installed in single rack slot; must cooperate with 3500/22M TDI module. ‑ Verify rack firmware and configuration‑software version compatibility before replacement.
3. After replacement, check OK LED status; download rack configuration project, verify Ethernet link, EGD/Modbus data read‑out, remote configuration function.

4. Common failure mode: Network interface circuit damage, component aging; Ethernet / serial cable fault will cause communication loss, will not trigger machinery protection trip.
