3500 System Overview  Description  The 3500 System provides continuous, online monitoring suitable for machinery  protection applications, and is designed to fully meet the requirements of the  American Petroleum Institute’s API 670 standard for such systems. It represents  our most capable and flexible system in a traditional rack-based design, and  represents numerous features and advantages not provided in other systems.  The system’s highly modular design consists of:  • 3500/05 Instrument Rack (required)  • One or two 3500/15 Power Supplies (required)  • 3500/22M Transient Data Interface or 3500/20 Rack Interface Module  (required)  • One or two 3500/25 Keyphasor® Modules (optional)  • 3500 Rack Configuration Software (required)  • One or more 3500/XX Monitor Modules (required)  • One or more 3500/32 Relay Modules or 3500/34 TMR Relay Modules  (optional)  • One or more 3500/92 Communication Gateway Modules (optional)  • 3500/93, 3500/94, or 3500/95 display OR 3500 Operator Display  Software running on a compatible PC (optional)  • Internal or external intrinsic safety barriers, or galvanic isolators for  hazardous area installations (optional)  These are described in more detail in the following section and in the individual  datasheets for each system component.
