BENTLY 3500/22-01-01-00
Product Introduction
BENTLY 3500/22-01-01-00 is a Transient Data Interface (TDI) module that serves as the critical communication link between the 3500 monitoring system and host software (such as System 1™ Condition Monitoring and Diagnostic software). It combines the functions of a 3500/20 Rack Interface Module (RIM) with the data collection capabilities of a communication processor.
This module resides in the leftmost slot (Slot 1, adjacent to the power supply) of the 3500 rack. It interfaces with M-series monitors (e.g., 3500/40M, 3500/42M) to continuously collect steady-state and transient dynamic (waveform) data, passing it to the host computer via a 10/100 Base-T Ethernet link. While it provides essential diagnostic data, it is not part of the critical protection path and will not affect the system’s mechanical protection functions.
Key Technical Specifications

Quality Control Process (Engineer’s Perspective)
- Incoming Verification: Trace source via serial number. Inspect front panel USB port and rear Ethernet connectors for physical damage.
- Visual Inspection: Verify LED indicators and hardware DIP switches (supports up to 127 addresses).
- Live Functional Test: Install in Slot 1. Verify “OK” and “CONFIG OK” LEDs illuminate. Check TX/RX activity during data polling.
- Communication Test: Connect via Ethernet to host PC. Verify successful handshake with System 1 software or 3500 Configuration Software.
- Final QC & Packaging: Seal in anti-static bag. Apply QC Passed label with date.

Replacement Pitfall Guide
❗ Slot 1 Mandatory: The 3500/22-01-01-00 must be installed in Slot 1 (immediately adjacent to the power supply). Installing it in any other slot will prevent rack communication.
❗ RIM vs. TDI: This module replaces the need for a separate 3500/20 RIM. Do not install both a 3500/20 and a 3500/22 in the same rack. Each rack requires exactly one RIM or one TDI.
❗ Protection Path Independence: While critical for diagnostics, the TDI is not part of the critical monitoring/protection path. A TDI failure will not cause machinery protection relays to trip.
❗ TMR Configuration: The “-01-” in the part number denotes a Standard (non-TMR) TDI. If your rack is configured for Triple Modular Redundancy (TMR), you must use a TMR-rated TDI (e.g., 3500/22-02-xx-xx) instead.
❗ Transient Data Licensing: Standard static data collection is built-in. To capture high-resolution transient waveforms, ensure the optional channel enable disk/key is installed and configured in the software.
Keep these in mind and you’ll cut 90% of rework time.
Compatibility Matrix & Benchmarks
- 3500/22-01-01-00 → 3500/22-01-02-00 : Needs Adaptation — Standard TDI vs. Fiber Optic (100 Base-FX) I/O
- 3500/22-01-01-00 → 3500/20 : Alternative — Standard RIM (no transient data collection capability)
- 3500/22-01-01-00 → 3500/22-02-01-00 : Incompatible — Standard vs. TMR application
Benchmarks:
- Ethernet Link Negotiation: Auto-negotiates 10/100 Base-TX
- Data Polling Latency: < 100 ms for steady-state values
