Description
Bently Nevada 3500/22‑01‑01‑00 Standard Transient Data Interface Module, 10/100Base‑T Ethernet for 3500 Machinery Protection Rack
Product Introduction
The 3500/22‑01‑01‑00 (commonly known as 3500/22M TDI) is the mandatory rack interface & data gateway for Bently Nevada 3500 machinery protection system. It combines the functions of old‑generation 3500/20 Rack Interface Module and transient data communication processor. Installed in Slot #1 (adjacent to rack power supply), it communicates with all M‑series monitor boards via rack backplane bus, collecting steady‑state parameters as well as high‑speed transient vibration waveform data. It uploads full‑rack machinery information to System 1® condition monitoring diagnostic software through 10/100Mbps Ethernet port. The front USB port supports local rack configuration via 3500 rack software. It carries the rack‑OK relay for overall rack health alarm output. TDI is not part of the protection trip path, replacement will not affect the normal protection & shutdown logic of vibration/thrust monitors. Every single 3500 rack requires one TDI or RIM module. It is a high‑demand spare for turbine & compressor monitoring cabinet maintenance.
Specific Application Information
- Rack master interface: Synchronize backplane timing bus for all monitoring modules inside the 3500 rack.
- Transient waveform capture: Collect high‑resolution vibration waveform, Keyphasor phase data for post‑trip fault analysis.
- System 1 software connection: Real‑time upload of vibration, thrust, speed, temperature data to Bently Nevada System1 diagnostic platform.
- Rack global status monitoring: Detect module loss, communication failure, rack power fault and trigger Rack‑OK relay alarm.
- Local configuration access: Front USB port for laptop connection to configure all monitor parameters, alarm setpoints.
- Static process data transmission: Send steady‑state machinery readings to upper HMI / DCS via network.
- Event & alarm timestamping: IRIG‑B time sync support for unified time mark of all machinery alarms and transient records.
- TDI ordering code explanation:
- 01 = Standard TDI main board
- 01 = I/O sub‑board with 10/100TX Ethernet
- 00 = No hazardous area agency certification
