Product details

The 3500/20 Rack Interface module is the main interface of the 3500 rack and supports a proprietary protocol for configuring the rack and retrieving mechanical information. The interface module must be installed in slot 1 of the rack (next to the power supply). RIM supports compatible Bently Nevada external communications processors such as TDXnet, TDIX, and DDIX. Although RIM provides some common features for the entire rack, it is not part of the critical monitoring path and does not affect the normal operation of the overall monitoring system. Each rack requires a RIM.

In Triple Modular Redundant (TMR) applications, the 3500 system requires a TMR version of RIM. In addition to all the features of standard RIM, TMR RIM also performs a "Monitor channel comparison" function. The 3500 TMR configuration implements monitoring voting using the Settings specified in the monitoring options. In this way, TMR RIM constantly compares the output from the three redundant monitors. If TMR RIM detects that the information for one of the monitors is no longer within the configured percentage range of the information for the other two monitors, it flags that monitor as an error and logs an event in the system event list.

Specification parameters:

Input:

Power consumption: Typical value is 4.75 watts

Data: Front panel standard RS232 serial communication

Data rate: 38.4k baud

I/O module standard: RS232/RS422 serial communication, internal modem communication

Data rate: up to 38.4k baud for serial communication and 14.4k baud for internal modem communication

Output:

Front panel LED:

OK LED: Indicates that RIM is working properly

TX/RX LED: Indicates RIM to communicate with other modules in the 3500 rack

TM LED: Indicates that 3500 rack is in a triple failure state

CONFIG OK LED: Indicates that 3500 rack has a valid configuration

I/O module OK relay: indicates that the 3500 rack is operating properly or that a fault has been detected within the rack

The user can select the "On" or "Off" status to indicate the rack status

To sum up, the 3500/20 rack interface module plays a crucial role in the 3500 rack, not only as a bridge between the rack and the outside, but also in certain situations (such as in TMR configurations) to perform advanced monitoring and comparison functions. Through its standard RS232 serial communication interface and internal modem communication, users can easily configure the rack, retrieve mechanical information, and monitor the operating status of the rack. At the same time, its rich LED indication and relay output functions allow users to intuitively understand the working status and potential failures of the rack. Whether it is a single rack application or a triple modular redundancy system, the 3500/20 rack interface module is a key component to ensure proper system operation and efficient maintenance.
