Module Type: Transient Data Interface (TDI) Module designed for the 3500 series machinery monitoring rack

Power Input (Backplane)

Power source: Powered through the 3500 rack backplane

Typical power consumption: 10.5 W

Signal & Hardware Inputs

Keyphasor® Input

Compatible with proximity probe signals or magnetic pickup signals for speed measurement and phase reference; supports 1 to 4 Keyphasor inputs sourced from field transducers.

Dry Contact Control Inputs

Includes Trip Multiply Inhibit, Alarm Inhibit and Rack Reset inputs. Dry contact design with typical DC input current less than 1 mA.

Front-panel Communication Interfaces

Auto-sensing 10/100Base-TX Ethernet port and USB-B port, dedicated to local parameter configuration and data retrieval.

Outputs

Timing Synchronization Output

Generates TTL-level timing pulses to the rack backplane, enabling synchronous transient waveform sampling among all monitor modules.

Rack OK Relay Output (Normally Energized)

Contact rating: 5 A at 24 VDC / 120 VAC; maximum switching capacity: 600 VA / 120 W. Provides fault alarming signals when rack malfunctions occur.

Communication Data Output

Transmits steady-state measurement data, transient waveforms and spectrum information to host PCs or System 1 monitoring software via Ethernet or USB connection.

Front-panel Status Indication Outputs

Equipped with OK, TX/RX, TM and CONFIG OK LED indicators to visually reflect module running condition and communication status.

Case 1: Steam Turbine Monitoring in Thermal Power Plants

Combined-cycle power plants adopt the 3500 rack equipped with the 3500/22 TDI module to monitor steam turbines and generator units.

The module receives Keyphasor signals and vibration data from monitoring modules, achieving synchronous waveform sampling of all measurement channels during unit startup, shutdown and load variations. Steady-state parameters and transient vibration waveforms are uploaded to System 1 software via Ethernet. Engineers analyze rotor imbalance, misalignment and bearing faults using complete data records to carry out predictive maintenance and prevent unplanned shutdowns. The Rack OK relay outputs remote fault alarms for the machine protection rack.

Case 2: Condition Monitoring of Centrifugal Compressors in Petrochemical Plants

Major refineries deploy the 3500 monitoring system with 3500/22-01-01-00 for process centrifugal compressors.

The TDI collects signals including shaft vibration, axial displacement and rotating speed. It automatically captures pre-alarm and post-alarm transient data once abnormal vibration alarms are triggered, and uploads all diagnostic data to the factory monitoring platform. Field technicians detect early gear meshing faults and rotor rubbing through waveform and spectrum analysis. The dry contact control inputs support alarm inhibit and rack reset to facilitate safe maintenance.

Case 3: Gas Compressor Monitoring on Offshore Oil & Gas Platforms

The 3500/22 acts as a data communication hub for natural gas compressors on offshore production platforms.

It gathers multi-channel dynamic measurement data and transmits high-resolution transient records to onshore monitoring centers. Suited for compact cabinets and stringent offshore safety specifications, the front-panel USB port enables local offline configuration. Synchronized timing pulses guarantee uniform sampling for comparison among multiple devices, helping operators continuously monitor equipment health under severe offshore environments.

Case 4: Protection and Diagnosis of Large Blowers in Metallurgical Plants

Steel mills implement the 3500 system for main exhaust blowers, with the 3500/22 handling unified internal data scheduling within the rack.

Synchronous transient data recording activates during blower speed regulation and resonance crossing. Historical vibration trends and waveform archives support assessment of fan rotor fatigue damage. The monitoring system connects to the plant DCS, allowing operators to check key machine parameters together with process data on a unified interface.

General Application Scope

Power industry: steam turbines, gas turbines, generators, feedwater pumps

Oil, gas & petrochemical industry: centrifugal and reciprocating compressors, process pumps

Metallurgy and papermaking: large blowers, rolling mill drive units
