Bently Nevada 176499-03 Monitor Module

This monitor module provides comprehensive machinery protection through configurable measurement channels. It serves as a universal monitoring solution for various machine parameters. The 176499-03 offers flexible configuration for position, vibration, and speed measurements.

Core Measurement Specifications

The module supports up to two independent measurement channels for versatile monitoring tasks. Each channel accepts inputs from proximity probes, velocity transducers, and accelerometers. Furthermore, the unit provides 16-bit resolution for accurate signal acquisition and analysis. It offers selectable filter ranges from 1 Hz to 10 kHz for diverse applications. The monitor handles both AC and DC input signals for maximum flexibility.

Connectivity and Signal Processing

The front panel includes BNC connectors for each channel’s input signal. These connectors provide reliable 50-ohm impedance for high-frequency signals. Additionally, the 176499-03 features a 10-pin terminal block for relay and status outputs. Each channel includes dedicated LED indicators for alarm and trip conditions. Engineers can configure processing parameters through the 3500 configuration software.

Alarm Configuration and Protective Functions

The module includes four fully programmable alarm setpoints per channel. Each alarm can activate at user-defined amplitude thresholds with time delays. Furthermore, the 176499-03 supports both latching and non-latching alarm behaviors. The unit provides a bypass function for safe maintenance access. It also offers a dedicated OK relay for self-health status annunciation.

Mechanical Specifications and Environmental Ratings

The module measures 24.1 x 5.2 x 4.5 centimeters and weighs approximately 0.7 kilograms. Its single-slot design fits into any compatible 3500 rack position. The operating temperature range spans -20°C to +65°C with 95% non-condensing humidity tolerance. Moreover, the 176499-03 features gold-plated edge connectors for long-term reliability.
