Product Introduction
The Bently Nevada 3500/22M 138607‑01 Transient Data Interface Module serves as the communication backbone between the 3500-Series monitoring rack and host systems like System 1. Slotting adjacent to the power supply, this module combines steady-state and transient waveform capture with Ethernet output, enabling detailed machinery diagnostics. It’s not part of the critical trip path, meaning it can be removed or serviced without disrupting machine protection—ideal for environments demanding both reliability and accessibility.

Frequently Asked Questions (FAQ)
-
What is the primary role of the 3500/22M TDI?
It gathers steady-state and transient vibration data and sends it to host software via Ethernet. -
Can I remove it without shutting down the system?
Yes—it’s hot‑swappable and not in the protection trip path. -
What network options does it support?
Supports both 10Base‑T and 100Base‑TX Ethernet (auto-negotiation). -
How are data events triggered?
Events are captured automatically or via optional channel enable configurations. -
Does it support firmware upgrades?
Yes, compatible with System 1 and configuration tools. -
What diagnostics are visible when it operates?
LEDs indicate rack status and communication health; alarm relay signals faults. -
What is the relay’s purpose?
It provides a normally-energized contact that trips on rack faults. -
How do I secure configurations?
Use the keylock to switch between RUN and PROGRAM modes. -
Can it detect transient pattern deviations?
It records waveform data, which sophisticated analysis tools in System 1 can evaluate. -
Is it suitable for harsh or explosion-prone areas?
Yes, it can be ATEX certified when mounted appropriately.
