Product Overview
Housed in Slot 1 of the 3500 rack—adjacent to power supplies—the TDI component merges the functionality of a 3500/20 Rack Interface Module (RIM) with the data-gathering prowess of a communication processor like TDXnet. It interfaces with M series monitors (e.g., 3500/40M, 3500/42M) to collect steady-state metrics, transient waveforms, and dynamic data, which are then transmitted via Ethernet to host software for real-time analysis.
Crucially, the 3500-22M operates outside the critical monitoring path, ensuring it never compromises the 3500 system’s core machinery protection capabilities. Every 3500 rack requires either a TDI or RIM, making this module indispensable for system completeness. The I/O Module enhances usability by offering rear-panel connections, enabling remote activation of key functions such as System Reset, Trip Multiply, and Rack Alarm Inhibit.

FAQ
What makes the 3500-22M essential for 3500 Machinery Protection Systems?
The 3500-22M serves as the critical data bridge between the 3500 system and host software, collecting and transmitting vital machinery data. Its I/O capabilities also enable remote control of key functions, making it a linchpin for system operation.
Will installing the 3500-22M impact the system’s protective functions?
No. The module is designed to operate outside the critical monitoring path, so it never interferes with the 3500 system’s ability to trigger automatic machinery protection measures.
How do I enable dynamic transient data capture?
Dynamic and high-resolution transient data capture is not standard. Users must install an optional Channel Enabling Disk to unlock this feature, allowing deeper analysis of machinery behavior.
What Ethernet type is best for my facility?
Choose 10Base-T/100Base-TX (copper) for short-distance, cost-effective setups. Opt for 100Base-FX (fiber optic) for longer distances or environments with electromagnetic interference. Gold-plated contacts are ideal for high-vibration or corrosive settings.
Is the 3500-22M suitable for use in explosive environments?
Yes, when configured with Code 01 (CSA/NRTL/C Class 1, Division 2) or Code 02 (multi-certification including ATEX and IECEx), it meets safety standards for hazardous locations.
The 3500-22M TDI and IO Module from Bently Nevada delivers unmatched integration, reliability, and flexibility, making it a vital component for industrial machinery monitoring and protection.
