Bently Nevada 3500/20-02-02-00 Rack Interface Module
Description：
3500/20-02-02-00 is a set of TMR Rack Interface Module 125744-01 with RIM I/O Module with RS232/RS422 Interface 125768-01.
For TMR applications, the 3500 system requires a TMR version of the RIM. In addition to all the standard RIM functions, the TMR RIM also performs "monitor channel comparison." The 3500 TMR configuration executes monitoring voting using the setup specified in the monitor options. Using this method the TMR RIM  continually compares a specified output of 3 redundant monitors. If the TMR RIM detects that the information from one of those monitors is no longer equivalent (within a configured percent) to the remaining two, it will flag the monitor as being in error and place an event in the System Event List.
The Rack Interface Module uses two I/O module types, the Rack Interface I/O Module and the Data Manager I/O Module. These I/O modules let you connect a 3500 host computer and Communication Processors (TDIX or DDIX) to a 3500 rack and let you daisy chain racks together.
Only one Rack Interface I/O Module can be installed at a time behind the Rack Interface Module (in a Rack Mount or a Panel Mount rack) or above the Rack Interface Module (in a Bulkhead rack).
Also, one Data Manager I/O Module may be installed between the Power Input Modules and the Rack Interface I/O Module (in a Rack Mount or a Panel Mount rack) or above the Power Supplies between the Power Input Modules and the Rack Interface I/O Module (in a Bulkhead rack).
