Bently Nevada 88984-02| 3300 Series Option Card

Product Overview

The Bently Nevada 88984-02 is a vital interface component within the legacy 3300 Series Machinery Protection System. Formally categorized as an Input Relay Option Card, this specific "-02" version is a "No Relays" variant. It serves as the physical termination point for field wiring, specifically for dual-channel (Dual OT) monitoring applications.

Key Features and Engineering Advantages

• Dual Channel Support: Designed to handle inputs for two independent monitoring channels (such as XY vibration or Dual Thrust), providing a centralized termination point for a single bay.

• Screw-Type Terminals: The heavy-duty screw terminals provide superior mechanical retention for field wiring, essential for environments with high ambient vibration.

• Reliable Signal Path: Engineered to maintain the high signal-to-noise ratio required for precision eddy-current proximity probe signals.

• Modular Compatibility: Designed to work seamlessly with the 3300 rack backplane, allowing for straightforward replacement of failed interface cards without re-engineering the system.

• Industrial Durability: Even as a legacy PC board, the 88984-02 is built with industrial-grade components designed for decades of continuous operation in power plants and refineries.
