The 3500/22M 138607-01 is a transient Data interface (TDI) module developed by Bently Nevada, part of the 3500 series of components designed for data acquisition and transmission in industrial automation systems. Here’s how:
Functional characteristics
Data interface function: It is the interface between the 3500 monitoring System and compatible software (such as System 1 condition monitoring and diagnostic software, 3500 system configuration software), combining the functions of 3500/20 rack interface module (RIM) and the data collection functions of communication processors such as TDXnet.
Data acquisition capability: Connected with M-series monitors (e.g. 3500/40M, 3500/42M, etc.), steady and transient dynamic (waveform) data can be continuously collected and transmitted to the host software via Ethernet links. Static data capture is standard, and an optional channel-enabled disk also captures dynamic and high-resolution transient data.
Supported Running mode: 3500/22m 138607-01 Can be used to set the 3500 rack to RUN or PROGRAM mode. RUN mode allows the rack to run properly, but prevents configuration changes; PROGRAM mode allows for normal operation and local or remote rack configuration.

Data collection features: 3500/22M 138607-01 can collect data at a predetermined speed and interval, and can be independently programmed to increase and decrease the speed interval. The number of transient events that can be collected is limited only by the memory available in the module. Static values are collected at 100-millisecond intervals 20 seconds before and 10 seconds after an event, and waveform data for specific time periods before and after an event can also be collected.
Signal support: Support for four Keyphasor signals of 3500 systems, support for speed input multiple times per revolution, up to 20kHz.
Technical specification
Power consumption: 10.5W.
Data front panel: Maximum 115.2kbaud.
