Bently Nevada 3500/20 125744-02 Standard Rack Interface Module

The Bently Nevada 3500/20 125744-02 is the Standard Rack Interface Module (RIM) for the 3500 Machinery Protection System. It is the primary interface used to configure the rack and retrieve machinery information.

Article & System Context

Product Profile

Baker Hughes specifies one RIM per 3500 rack, installed in slot 1 next to the power supplies. The RIM communicates with other 3500 modules and supports rack configuration and data collection.

The Standard RIM is intended for standard monitoring applications; Triple Modular Redundant installations use the separate TMR RIM version.

System Matching

Compatibility

3500/20 125744-02 is the Standard RIM for normal 3500 monitoring applications and requires the appropriate rear I/O module for external communications. It is not the TMR RIM used for triple-redundant monitor voting.
Typical Use

Applications

Standard 3500 Racks
Primary configuration and communication interface for standard monitoring racks.
Data Collection
Supports retrieval of machinery and rack information through compatible host communications.
Rack Configuration

External Communications
Works with compatible RIM I/O and Bently Nevada communication processors.
Customer Questions

Frequently Asked Questions

1. Is 3500/20 125744-02 the Standard or TMR RIM?
It is the Standard Rack Interface Module. The TMR RIM uses a different spare-part number.
2. Where must 3500/20 125744-02 be installed?
Baker Hughes specifies slot 1 of the rack, immediately next to the power supplies.
3. Does 3500/20 125744-02 affect the critical monitoring path?
Baker Hughes states that the RIM is not part of the critical monitoring path and does not affect normal monitoring operation.
4. What communications does 3500/20 125744-02 provide?
The front panel provides RS232 serial communications, while rear I/O options support the documented RS232/RS422 or modem interfaces.
5. What should be checked before ordering a replacement RIM?
Confirm Standard versus TMR type, rear I/O module, rack configuration, firmware revision and host communication requirements.
