BENTLY 3500/22M Transient Data Interface Module

The Bently 3500/22M is a Transient Data Interface (TDI) module developed by Bently Nevada, primarily used for condition monitoring and fault diagnosis of industrial equipment. Below is its detailed information:

1. Module Type

Transient Data Interface (TDI) Module

2. Functional Features

Data Collection: Capable of collecting both steady-state and transient dynamic (waveform) data, interacting with M-series monitors (e.g., 3500/40M, 3500/42M) and transmitting data to host software via an Ethernet link.
Keyphasing Function: Provides a pulse signal per revolution, which is used for phase reference and vibration analysis.
Alarm Output: Supports programmable over-speed or under-speed alarms, with relay outputs (normally open/normally closed).

3. Technical Parameters

Measurement Range: The vibration velocity measurement range is typically 0-1000 mm/s, with a frequency range of 1 Hz-1000 Hz.
Accuracy: Vibration measurement accuracy can reach ±5%.
Operating Temperature: -40°C to 80°C (-40°F to 176°F)
Supply Voltage: 24V DC
Communication Interfaces: Supports RS-485 and Ethernet
Output Signals: 2 relay outputs (Alarm 1/Alarm 2) with a contact rating of 30V DC/2A; optional analog output (4-20mA or 0-10V, configuration-dependent)
