Bently Nevada 133300-01 3500/15 Power Input Module

Product Overview

The Bently Nevada 133300-01 serves as the Low Voltage DC Power Input Module (PIM) for 3500 series machinery protection systems. This module works together with the Low Voltage DC Power Supply to deliver regulated power to all modules in the 3500 rack. The 133300-01 mounts directly behind the associated power supply, providing the interface between the incoming DC source and the power supply module.

The input voltage range spans from 20 to 30 Vdc, accommodating various industrial DC power sources. This PIM is an essential component for any 3500 series rack requiring low voltage DC power input. The module's compact design fits into the dedicated half-height slot behind the power supply, maximizing rack space efficiency.

Electrical Specifications

The 133300-01 supports a maximum full rack current draw of 11.0 A for low voltage DC configurations. This capacity ensures sufficient power delivery for fully populated 3500 racks with multiple monitoring modules installed.

The module includes comprehensive protection features. An under-voltage condition does not harm the supply or the PIM, ensuring continued operation during minor voltage dips. An over-voltage condition causes the fuse to open on the PIM, protecting both the power supply and all connected modules from damage. This protection mechanism safeguards the entire monitoring system from electrical faults.

Physical Specifications

The 133300-01 measures 120.7 mm in height, 25.4 mm in width, and 114.3 mm in depth (4.75 in x 1.0 in x 4.5 in). The weight is approximately 0.34 kg (0.75 lbs).

The module is a special half-height module located directly behind the associated power supply. This compact footprint allows for efficient use of rack space while maintaining proper power distribution. The module's design ensures easy installation and removal for maintenance purposes.

Rack Space Configuration

The 3500 series rack provides two half-height slots on the left side specifically for power supplies. Each slot accommodates one power supply, and both slots can hold a power supply simultaneously for redundant configurations.

The 133300-01 PIM occupies the half-height slot directly behind the associated power supply. In redundant configurations, two PIMs are required, each mounted behind its respective power supply. This arrangement provides organized power distribution and simplifies troubleshooting. No minimum rack load is required for operation, meaning the power system functions reliably even in lightly populated racks.

Environmental Specifications

The 133300-01 operates across a wide temperature range. The operating temperature spans from -30 °C to +65 °C (-22 °F to +150 °F), making this module suitable for various industrial environments. The storage temperature extends from -40 °C to +85 °C (-40 °F to +185 °F), allowing for safe storage in extreme conditions.

The humidity tolerance reaches 95% non-condensing, ensuring reliable performance in humid environments commonly found in industrial facilities. These environmental limits are consistent with other 3500 series modules, allowing the entire system to operate reliably in demanding conditions.

Hazardous Area Approvals

The 133300-01 carries extensive hazardous area approvals, making it suitable for installations in potentially explosive environments. The cNRTLus approval covers Class I, Zone 2 with AEx/Ex nA nC ic IIC T4 Gc and AEx/Ex ec nC ic IIC T4 Gc classifications, as well as Class I, Division 2, Groups A, B, C, and D, with T4 rating at Ta= -20°C to +65°C (-4°F to +149°F).

The ATEX/IECEx certification includes II 3 G classification with Ex nA nC ic IIC T4 Gc and Ex ec nC ic IIC T4 Gc, also rated T4 at Ta= -20°C to +65°C. These approvals enable the 133300-01 to be used in oil and gas facilities, chemical plants, and other locations where explosive atmospheres may be present. The module's intrinsic safety features ensure safe operation in these demanding environments.

Certifications and Compliance

The 133300-01 complies with multiple international standards and certifications. For electromagnetic compatibility, it meets the EMC Directive 2014/30/EU and follows EN 61000-6-2 for immunity and EN 61000-6-4 for emissions in industrial environments.

For electrical safety, the module complies with the LV Directive 2014/35/EU and meets EN 61010-1 standards. The RoHS Directive 2011/65/EU ensures the product is free from hazardous substances. The module also complies with FCC Part 15 rules, confirming that it does not cause harmful interference and accepts any interference received.

The 133300-01 carries maritime certifications from DNV GL for classification of ships, offshore units, and high-speed and light craft. Additionally, it meets ABS Rules for Condition of Classification, including Steel Vessels Rules and Offshore Units and Structures requirements. These certifications make the module suitable for marine and offshore applications.

Installation Guidelines

Installing the Bently Nevada 133300-01 requires attention to proper placement and connections. First, ensure the rack is powered down before inserting or removing any power input module. Next, slide the PIM into the half-height slot directly behind the associated power supply until it seats fully. Then, secure the module using the retaining screws.

The PIM provides the connection point for the incoming DC power source. Proper wiring practices should be followed, ensuring correct polarity and secure connections. The module's internal fuse provides protection against over-voltage conditions, and replacement requires accessing the module after disconnecting power.

For redundant configurations, install a second PIM behind the second power supply. Each power supply should be connected to separate DC sources for true redundancy. This configuration ensures uninterrupted power delivery if one power source fails.

Maintenance and Troubleshooting

The 133300-01 requires minimal maintenance. Regular inspection of the connections and visual check of the associated power supply's OK LED provide quick verification of proper operation.

The internal fuse on the PIM protects against over-voltage conditions. If the fuse opens due to over-voltage, investigate the input power source before replacing the fuse or PIM. Under-voltage conditions do not damage the module, allowing for automatic recovery when normal voltage returns. The module's robust design ensures long-term reliability in demanding industrial environments.
