Functional Description

3500/20 is a Rack Interface Module designed and developed by Bently Nevada. The primary interface to the 3500 rack is the Rack Interface Module (RIM). It supports a proprietary protocol for configuring the rack and retrieving machinery data. The RIM must be placed in rack slot 1. (next to the power supplies). Compatible Bently Nevada external communications processors such as TDXnet, TDIX, and DDIX are supported by the RIM. While the RIM performs some functions that are shared by the entire rack, it is not part of the critical monitoring path and has no effect on the overall monitoring system's proper, normal operation. Each rack requires one RIM.

Features

• The 3500 System requires a TMR version of the RIM for Triple Modular Redundant (TMR) applications.
• The TMR RIM performs "monitor channel comparison" in addition to all of the standard RIM functions. Monitor voting is implemented in the 3500 TMR configuration using the setup specified in the monitor options.
• The TMR RIM continuously compares the outputs of three (3) redundant monitors using this method. If the TMR RIM detects that the information from one of those monitors is no longer within a predefined percentage of the information from the other two monitors, it will flag the monitor as being in error and record an event in the System Event List.

Product Attributes

• Primary Connection to the 3500 Rack
• Supports a Private Protocol
• It must be placed in Slot 1.
• Supports communication processors like TDXnet, TDIX, and DDIX.

Front Panel LEDs

OK LED

• When the RIM is operational, this value is set to 1.

RX/TX LED

• When the RIM is communicating with other modules in the 3500 rack, this value is displayed.
• When the 3500 rack is in Trip Multiply mode, the TM LED illuminates.

CONFIG OK LED

• Indicates that the 3500 rack is configured correctly.

I/O Module OK Relay

• When the 3500 rack is operating normally, the relay will signal that a fault has been detected within the rack.
• To indicate a NOT OK condition, the user can select either a "OPEN" or "CLOSED" contact.
  This relay is always "Normally Energized."

OK relay

• Rated at 5 amps @ 24 volts/120 volts, 120 watts/600 volts switched power.

Normally closed contacts

• Arc suppressors are supplied.
