Mechanical Data

‑ Dimension(H×W×D):241.3 mm ×24.4 mm ×241.8 mm ‑ Weight: approx 0.80 kg

Core Functions

1. High‑speed EGD gateway: Real‑time bidirectional high‑capacity data exchange with GE Mark VIe turbine control system, improved refresh performance vs old‑revision 3500/91.
2. Multi‑protocol data output: Upload vibration, position, speed, temperature, alarm events, rack fault status to DCS, historian, System‑1 via Modbus‑TCP / Modbus‑RTU.
3. Remote rack configuration: Support 3500 Rack Configuration Software online connect, download/upload rack project parameters over 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. Enhanced self‑diagnosis: Detect backplane communication fault, Ethernet link fault, serial‑port fault; report module hardware fault and detailed network diagnostic information 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 190798‑01 or fiber‑optic 190806‑01; select according to field network layout. ‑ 3500/91M (190782‑01) cannot swap main‑board or rear‑I/O with legacy 3500/91 (161204‑01). ‑ Only one 3500/91M 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.
