Product Overview

The Bently Nevada 88199-01 (associated with assembly 88286-01H) functions as a high-precision Temperature Control Printed Wiring Assembly (PWA) for the legacy 3300 Machinery Protection System. This module specializes in acquiring, linearizing, and processing thermal data from RTDs or thermocouples installed on critical rotating assets. By integrating directly into the 3300 rack, the 88199-01 provides the essential logic for temperature-based alarms and automated machinery protection. We provide this component as 100% Brand New and Original in Factory Packing, ensuring the continued safety of your turbines, compressors, and large industrial motors.

Technical Specifications

Engineering Advantages

• High-Accuracy Thermal Acquisition: The 88199-01 utilizes advanced signal conditioning to convert low-voltage sensor inputs into stable temperature data. This accuracy prevents nuisance alarms while ensuring the system triggers protective trips the moment temperatures exceed safe mechanical limits.

• Seamless Rack Integration: Designed specifically for the Bently Nevada 3300 chassis, this PWA slides directly into the designated monitor slot. It communicates via the internal rack bus, allowing other modules (such as relay assemblies) to act upon the processed temperature data instantly.

• Industrial Noise Immunity: The board layout incorporates heavy-duty shielding and filtering to reject electromagnetic interference (EMI). This ensures that nearby high-voltage equipment, such as large variable speed drives or generators, does not corrupt the sensitive temperature readings.

• Extended Service Life for Legacy Racks: As an authentic OEM spare part, the 88199-01 allows facilities to maintain their 3300-series protection loops without the massive cost of a full system migration. It restores original factory performance and alarm reliability.

• Robust Component Selection: Bently Nevada uses industrial-grade capacitors and semiconductors on the 88286-01H assembly. These components withstand the constant thermal cycling and vibration levels present in turbine hall environments.

FAQs

• Can the 88199-01 be used in a 3500 series rack?

  No. The 88199-01 belongs to the 3300 series architecture. The 3500 series uses the 3500/60 or 3500/65 modules, which use a different physical form factor and communication protocol.

• What is the difference between part number 88199-01 and 88286-01H?

  88199-01 is the top-level orderable part number for the assembly, whereas 88286-01H is the specific PWA (Printed Wiring Assembly) number usually found silkscreened on the circuit board itself. They refer to the same functional unit.

• Does this module support both RTDs and Thermocouples?

  Yes. Depending on the jumper settings and configuration of the 3300 monitor, this board processes signals from standard 3-wire RTDs or various thermocouple types (J, K, T, etc.).

• Is this a refurbished or used board?

  No. We guarantee that every 88199-01 we ship is 100% Brand New and Original. It arrives in original anti-static factory packaging to ensure zero-hour reliability for your mission-critical protection system.
