Bently Nevada 87870-01 Serial Data Interface 3300
Overview
The Bently Nevada 87870-01 is the printed wiring assembly (PWA) of the 3300 System Serial Data Interface (SDI) module, the interface that connects a 3300 rack to a host computer over a serial link. It is a genuine Bently Nevada spare used with the 3300/03 System Monitor to exchange static data between the monitoring rack and the plant information system.
In a 3300 monitoring system the SDI option gathers the static measurement values from the rack and makes them available to a host system, complementing the Dynamic Data Interface (DDI) which streams dynamic waveforms. The Bently Nevada 87870-01 PWA is the heart of that interface card and is the correct replacement when the original SDI board fails.
Engineering & Design
The Bently Nevada 87870-01 is described in the official 3300 System Serial Data Interface and Dynamic Data Interface Operation Manual as the SDI hardware of the 3300/03 System Monitor. The SDI collects static data from the monitor channels and transmits it to a host system, while the DDI provides dynamic data transfer; both are options available with the 3300/03 System Monitor.
In practice the SDI module appears in the 3300 rack as the interface card that the host computer polls for the steady-state values of every connected monitor channel: overall vibration, gap, temperature and process signals. Because the SDI shares the rack with the 3300/03 System Monitor, its communication parameters must match the host configuration, and the associated manuals cover the exact wiring and register mapping. For plants running data historians or control-room workstations, keeping a spare 87870-01 board on the shelf avoids long downtime when the original card degrades, since the module is no longer in current production .
Installation and troubleshooting follow the 3300 System manual set: system overview (80171-01), installation instructions (80172-01) and troubleshooting (80173-01), together with the 3300/03 System Monitor manual (89604-01). The SDI/DDI hardware upgrade kit carries part number 104006-01 and the firmware upgrade kit 104007-01.

Compatibility
The Bently Nevada 87870-01 SDI module is compatible with the 3300/03 System Monitor and the 3300 rack family. It works alongside the 3300/12 power supply and the 3300/03 System Monitor modules, and pairs with the Dynamic Data Interface option for full data access.
Ordering Information
Order the Bently Nevada 87870-01 Serial Data Interface PWA as the direct replacement for the SDI board in your 3300 rack. Confirm the firmware level of your 3300/03 System Monitor; the SDI/DDI firmware upgrade kit 104007-01 is available for older monitors.
The 87870-01 serial data interface links the 3300 monitoring system to the host computer, and the interface supports the data acquisition of the vibration parameters.
The Bently Nevada 87870-01 serial data interface connects the vibration rack to the plant historian and the DCS for the continuous values.
