Bently Nevada 128276-01 Expansion Panel

Panel Overview

The Bently Nevada 128276-01 half future expansion panel provides additional mounting space for 3500 monitoring system modules. This passive panel extends the chassis capacity for future I/O requirements. It accommodates up to 4 additional monitoring modules in a half-height configuration. System designers use this panel for scalable machinery protection architectures.

Physical Dimensions and Panel Design

The Bently Nevada 128276-01 measures 220 millimeters in width and 180 millimeters in height. Its depth totals 150 millimeters for standard panel mounting. The unit weighs 1.8 kilograms for sturdy installation. The panel features a half-height form factor for space-constrained cabinets. This compact design suits retrofit and upgrade projects.

Module Capacity and Slot Configuration

This expansion panel provides 4 vacant slots for 3500 series monitoring modules. Each slot accepts standard 3500 monitor cards and communication modules. The panel includes backplane connectors for module insertion. All slots support hot-swappable module replacement. This capacity allows incremental system growth over time.

Backplane Connectivity and Power Distribution

The Bently Nevada 128276-01 includes a passive backplane for signal routing. It distributes power and communication signals to installed modules. The backplane connects to the main rack via a ribbon cable. This interconnection maintains system integrity and data flow. The panel draws power from the main 3500 rack supply.

Installation and Mechanical Integration

Mount the panel adjacent to the primary 3500 rack using supplied brackets. Secure it to the cabinet rails with standard M4 screws. Connect the panel to the main chassis using the provided cable. The panel positions flush with existing rack components. This integration maintains consistent module alignment for access.

Construction Materials and Quality

The Bently Nevada 128276-01 uses heavy-gauge steel for chassis construction. The panel features a powder-coated finish for corrosion resistance. Module guides use high-quality plastic for smooth insertion. The backplane uses gold-plated edge connectors for reliability. All materials meet Bently Nevada industrial standards.

Field Wiring Access and Cable Management

The panel provides front access for all field wiring connections. Cable routing channels exist at the top and bottom of the panel. The rear section includes cable tie points for neat bundling. Each slot has adequate clearance for terminal block access. This arrangement simplifies field installation and maintenance.

Future Expansion and System Planning

The Bently Nevada 128276-01 enables phased system growth without chassis replacement. It supports adding new module types as monitoring needs evolve. The panel maintains compatibility with the full 3500 module portfolio. This design protects the initial investment while allowing future upgrades. System engineers can plan capacity effectively.

Environmental Specifications

The panel operates between -20°C to +60°C ambient temperature. It withstands 10% to 95% non-condensing humidity conditions. The unit meets Bently Nevada enclosure specifications. The steel construction provides protection against mechanical damage. The design suits standard industrial control room environments.

Compatibility and System Integration

The Bently Nevada 128276-01 integrates with all 3500 rack configurations. It works with 3500/20, 3500/22, and 3500/25 monitoring systems. The panel supports 3500/40 and 3500/42 monitors without modification. It also accommodates communication gateways and relay modules. This broad compatibility ensures seamless system integration.
