Parameter Analysis

Each option block in the 129478-01 part number defines one element of the hardware configuration, from mechanical dimensions to connector style and approval suffix. The this Option specifies uses the High. The for all power supply Option specifies s, an. The unit is rated for operation from -30 °C to +65 °C.

Monitoring modules form the decision layer of the protection system, turning transducer signals into alarms and trips; keeping channels on consistent part numbers preserves documented measurement accuracy.

Application Scenarios

Within the protection rack, this module provides the channel-level processing that turns raw machinery measurements into actionable operator information.

Installation Guide

Insert the module into its designated rack slot, confirm the option string and position match the system configuration, wire the field terminals per the machine drawing, and verify channel alarms and trips before returning the protection system to service.

Compatibility

This component belongs to the 3500 series monitoring rack and is engineered to work with the associated probes, extension cables, Proximitors, and monitoring hardware of the same system. Bently Nevada components sharing the same part number are fully interchangeable, so a stocked spare can be fitted without re-engineering the measurement loop. TenBN can supply the complete chain under consistent part numbers.

Maintenance Advice

Review channel status, alarm settings, and module indicators during routine maintenance windows, and confirm field wiring integrity at the terminals. Keep the unit within its -30 °C to +65 °C operating envelope in service and storage.

Procurement Advice

Confirm the complete part number against your machine’s bill of materials before ordering, since each option digit changes the mechanical or electrical fit. TenBN stocks genuine Bently Nevada components and provides the official service documentation for this model. For inventory, pricing, and lead time on the 129478-01, contact [email protected].
