The condition monitoring system’s modular rack-based design includes the following components:

3500/05 Instrument Rack 

3500/15 Power Supplies

3500/22M Transient Data Interface (TDI) Module

One or more 3500/XX (mostly used are 3500/40M proximitor and 3500/16 temperature) Monitor Modules

One or more 3500/32M (4-channel) or 3500/33 (16-channel) Relay Modules

One or two 3500/25 Keyphasor Modules

One or more 3500/92 Communication Gateway Modules

3500 racks are available in two sizes: Full-size rack i.e. 19-inch rack with 14 available module slots. Mini-rack i.e. 12-inch rack with 7 available module slots.

The power supplies and rack interface module reside in the left-most part of the rack which is not counted as a slot i.e. remaining 14 for full and 7 for mini rack are used for other module installation.

Power Supply Module (3500/15)

The 3500/15 power supply is half heightened module installed on the leftmost side of the rack and installed one above the other creating a redundant system.

The respective parts are listed below and also shown in the above figure.
