Bently Nevada 330704-000-050-10-02-CN high-density relay module

Product Overview

The Bently Nevada 330704-000-050-10-02-CN is a high-density relay module for the 3500 Series Machinery Protection System. It provides programmable contact outputs to trigger machinery alarms or emergency shutdowns. This module ensures rapid, hardware-based intervention for critical assets like turbines and compressors by linking diagnostic alerts to physical control circuits.

Technical Configuration

Understanding the specific suffix codes of the 330704-000-050-10-02-CN is essential for ensuring system compatibility and regulatory compliance:

• 330704: The base part number for the 3500/33 16-Channel Relay Main Board.

• -000: Standard Option. Indicates a standard hardware assembly without specialized modifications.

• -050: I/O Module Type. Specifies the 16-Channel Relay I/O Module with Internal Terminations, allowing direct wiring to the rack.

• -10: Connector Type. Features standard Euro-style terminal connectors for secure field wiring.

• -02: Agency Approval. High-level certification for use in Class I, Division 2, or Zone 2 hazardous environments (ATEX/CSA/CE).

• -CN: Region Specific. Indicates full compliance with Chinese industrial standards and mandatory GB/T labeling requirements.

Specifications

This module features sixteen independent Single-Pole, Double-Throw (SPDT) relays, each capable of handling resistive loads up to 5A at 24 Vdc, 120 Vac, or 240 Vac. It operates with a typical response time of less than 10 milliseconds and requires a minimum switching load of 100 mA at 5 Vdc. Built for harsh industrial conditions, it maintains a rated operating temperature from -30°C to +65°C. The internal termination design streamlines cabinet space by eliminating the need for external interface cables and termination blocks.
