Bently Nevada 330709-000-050-50-02-00 definitive command-execution layer

Product Overview

The Bently Nevada 330709-000-050-50-02-00 acts as the definitive command-execution layer for the 3500 Machinery Protection System. Its core purpose is to bridge the gap between high-speed digital diagnostics and physical industrial control. By offering 16 independent, programmable relay channels, it provides the hardware-based "muscle" required to trigger automated emergency shutdowns or local annunciators. This module is essential for mitigating risks in high-value assets, ensuring that detected "Danger" conditions are met with near-instantaneous mechanical interlocking to prevent catastrophic failure.

Technical Configuration

The suffix string 330709-000-050-50-02-00 represents a specialized configuration tailored for specific wiring environments and international safety compliance:

• 330709: The base part number identifying the 16-Channel Relay Module main board.

• -000: No Modifications. Standard hardware version for universal application.

• -050: I/O Module Type. Specifies the 16-Channel Relay I/O Module with Internal Terminations (Discrete Wiring).

• -50: Specific Termination Option. Indicates a specialized terminal block style or physical mounting orientation for simplified cable management.

• -02: Agency Approval. Certified for use in hazardous areas (ATEX, CSA, and CE) suitable for Class I, Division 2 or Zone 2 locations.

• -00: Standard Revision. Confirms the assembly follows the latest baseline manufacturing design.

Specifications

Equipped with 16 Single-Pole, Double-Throw (SPDT) relays, this module offers a versatile array of Normally Open (NO) and Normally Closed (NC) contact options. Each relay is rated for a resistive switching capacity of 5A at 240 Vac or 24 Vdc. The response time is engineered for safety-critical speed, typically engaging within 10 milliseconds of a logic event. It features a robust industrial operating temperature range of -30°C to +65°C. Notably, the -050 I/O configuration allows for high-density wiring directly at the rear of the rack, optimizing enclosure space by removing the need for external DIN-rail interface blocks.
