Description
Bently Nevada 3500/91M (190782‑01) EGD Gateway Module
Product Overview
190782‑01 is the complete assembled unit of 3500/91M EGD Communication Gateway for the 3500 machinery‑protection system. Compared with older generation 3500/91（161204‑01+daughter card）:
- 3500/91: Split‑design, main board + separate daughter Ethernet card
- 3500/91M 190782‑01: Integrated single‑board design, RJ45 Ethernet port built‑on front panel, no separate daughter card requiredChangxin. It implements EGD v2.01 protocol (UDP/IP), realizes high‑speed bidirectional data exchange between 3500 rack and GE Mark VIe controllers. Supports Producer / Consumer mode. It is hot‑swappable single‑slot module for 3500/05 rack.
Marketing order codes：
- 3500/91M‑02‑00 = 190782‑01 (copper RJ45, the only hardware variant for 91M; no fiber version for 3500/91M)
- Fiber EGD requirement must use legacy 3500/91 + 161216‑02 fiber daughter‑card.

Key Features
- Integrated single‑board hardware: Built‑in RJ45 port, eliminate separate daughter‑card; simplify spare‑parts management. No fiber hardware option for 91M seriesChangxin.
- EGD high‑speed real‑time communication: Optimized for turbine/compressor control‑system integration, low latency for safety‑related machinery‑protection data transfer to Mark VIe controllers.
- Bidirectional Producer‑Consumer function:
- Producer: Publish channel measured values, Alert/Danger alarms, module health status from entire 3500 rack.
- Consumer: Accept external controller commands: Group Reset, Alarm Inhibit, Trip Multiply back to 3500 rack.
- Full rack backplane access: Read data from all monitor modules including rotating‑machinery (3500/42M) and reciprocating‑compressor monitors (3500/70M,3500/72M).
- Protocol limitation: Only EGD UDP/IP. No Modbus TCP/RTU. If Modbus is needed select 3500/92 gateway.
- Hot‑swap capable: Online replacement without rack power‑down.
3500/91 vs 3500/91M vs 3500/92 comparison
| Model | Part set | Hardware structure | Protocol | Interface |
|---|---|---|---|---|
| 3500/91 | 161204‑01 + 161216‑xx | Main board + separate daughter‑card | EGD v2.01 | RJ45 Copper / MT‑RJ Fiber |
| 3500/91M | 190782‑01 | All‑in‑one single‑board | EGD v2.01 | Only RJ45 Copper, NO fiber |
| 3500/92 | Complete assembled unit | Integrated board | Modbus‑TCP / Modbus‑RTU | + RS485 serial |
Typical Applications & Scenarios
Main Applications
- Bidirectional high‑speed link between 3500 machinery‑protection rack and GE Mark VIe turbine / compressor controller.
- Transmit vibration, displacement, rod‑position, impulse‑vibration values, alarm status and module health to Mark VIe.
- Receive controller commands for alarm inhibit, group reset, trip‑multiply function into 3500 rack.
Industry Scenarios
- Power generation: gas‑turbine, steam‑turbine generator sets with Mark VIe control system.
- Oil & gas: refinery centrifugal compressors, pipeline compressors, reciprocating‑compressor units controlled by Mark VIe.
Supporting / Matching Components
- Host rack: 3500/05 instrument rack
- Rack power supply: 3500/15 series power‑supply modules
- Configuration software: 3500 Rack Configuration Software (define EGD exchange tables, IP address, Exchange‑ID match Mark VIe setting)
- Peer controller: GE Mark VIe or other EGD‑compliant controller
Related & Reference Part Numbers
- 161204‑01: Main board for legacy split‑type 3500/91
- 161216‑01: Copper daughter‑card for legacy 3500/91
- 161216‑02: Fiber daughter‑card for legacy 3500/91
- 3500/91M‑02‑00: Marketing model for assembled unit 190782‑01
- 3500/92: Modbus‑TCP / RTU gateway for DCS & SCADA
Installation & Maintenance Notes
- 190782‑01 is self‑contained integrated module; no daughter‑card needed. Do NOT use 3500/91 daughter‑cards with 3500/91M.
- Configure EGD Producer and Consumer tables inside configuration software, ensure IP address, Exchange‑ID consistent with Mark VIe controller.
- Isolate control‑system Ethernet from office LAN for network security.
- After installation verify OK LED status, EGD link health, data consistency between rack and Mark VIe controller.
- Hot‑swap replacement strictly follow Bently Nevada official service manual.
