Product Introduction (Structure B: Architecture hook)
This TDI module occupies slot 1 of the 3500 machinery protection rack and serves as the primary bridge between the 3500 monitor backplane and external condition monitoring hosts. It merges rack interface and high-speed data capture functions, pulling steady-state values and high-resolution transient waveform data from all populated monitor cards in the chassis.
It does not participate in the protective voting logic that triggers machine trips, a key separation that keeps safety functions isolated from diagnostic data paths. (This functional segregation is explicitly reviewed during API 670 third-party audits.) The conformal-coated PCB protects memory and Ethernet circuitry from dust and condensation inside non-conditioned control rooms.

Global Compliance & Industry Certifications
- CE Mark
- UL/cUL Listed
- SIL 2 capable (system-level evaluation required)
- ATEX / IECEx available for qualified production lots
- API 670 compliant for machinery monitoring applications
The UL/cUL listing defines PCB creepage and material flammability ratings, preventing internal arc spread if onboard memory or communication components fail. Verify specific lot certifications with OEM.
Long-Term Storage & Asset Preservation Guide
Keep the module sealed in its original ESD shielding bag and shipping carton for shelf storage. Electrostatic discharge can corrupt nonvolatile firmware storage and disable Ethernet communication after rack insertion.
Inspect electrolytic capacitors every 24 months for assets stored longer than three years. Controlled voltage reforming is required for spares held past four years; degraded capacitance creates packet loss during high-speed waveform capture.
Do not stack heavy rack modules on the module faceplate. Compressive force can bend edge connector pins and crack conformal coating, allowing contaminant buildup on high-speed signal traces.
Physical Installation Prerequisites
Leave a minimum of 40 mm vertical clearance above and below the populated 3500 rack for convection cooling. Elevated junction temperatures increase Ethernet bit error rates during long waveform capture sessions.
Slide the module fully into the dedicated slot 1 position until the front latch locks the edge connector to the backplane. Tie the rack chassis to plant instrument earth; floating ground potentials introduce common-mode noise that disrupts data transfer to System 1 hosts.
Buyer’s FAQ
Q: What HS tariff code applies to Bently Nevada 138607-01 for cross-border shipments? A: Primary HS classification falls under 853710 for electronic monitoring and communication assemblies for rotating machinery protection. Confirm classification with your customs broker before export filings, as rulings depend on supporting technical documentation.
Q: What country of origin is marked on Bently Nevada 138607-01? A: Country of Origin is United States. This marking appears on the module nameplate and must be reproduced on commercial invoices for cross-border compliance audits.
Q: Does 138607-01 ship preloaded with factory firmware? A: Yes. Base firmware is factory loaded. Network IP addressing and waveform capture parameters must be configured via 3500 configuration software after rack integration.
Q: Should I purchase all-risk shipping insurance for this spare TDI module? A: Yes. Edge pin damage or hidden PCB microcracks from transit shock may only surface once powered and streaming transient vibration data. All-risk insurance covers full replacement value for handling defects.
