Description
Bently Nevada 3500 system module
For three-module redundancy (TMR) applications, the 3500 system requires RIM in the form of TMR. In addition to all standard RIM functions, TMR RIM also has a "monitor channel comparison" function. The 3500 TMR configuration performs monitoring voting according to the settings specified in the monitoring options. In this way, TMR RIM will continuously compare the output of three mutually redundant monitors. If TMR RIM detects that the information of one monitor is not equal to the information of another monitor (within a set percentage), it will mark the monitor as an error and generate an event in the system event list.
The 3500 System provides continuous, online monitoring suitable for machinery protection applications, and is designed to meet the requirements of the American Petroleum Institute’s API 670 standard for such systems. The system’s modular rack-based design includes the following components:
• 3500/05 Instrument Rack (required)
• One or two 3500/15 Power Supplies (required)
• 3500/22M Transient Data Interface (TDI) Module (required)
• One or more 3500/XX Monitor Modules (required)
• One or more 3500/32M (4-channel) or 3500/33 (16-channel) Relay Modules (optional)
• One or two 3500/25 Keyphasor* Modules (optional)
• One or more 3500/92 Communication Gateway Modules (optional)
• Input/Output (I/O) Modules (required)
• 3500/94M VGA Display (optional)
• Internal or external intrinsic safety barriers, or galvanic isolators for hazardous area installations(optional)
• 3500 System Configuration Software (required)
