176449-02 Bently Nevada Redundant Power Supply Module 50-60Hz 12/24VDC (0.5A)

176449-02 Description

176449-02 Key Features

• 4-Channel Universal Input: Supports simultaneous connection to up to four proximity, velocity, or acceleration transducers for multi-parameter monitoring.
• Dual-Function Channel Pairing: Channels are programmable in pairs, capable of executing two distinct monitoring functions concurrently (e.g., vibration & thrust position).
• Wide Measurement Coverage: Programmable for radial vibration, axial thrust position, differential expansion, shaft eccentricity, REBAM (bearing wear), absolute shaft vibration, and speed.
• High-Sensitivity Signal Processing: Offers selectable measurement sensitivities for high-precision detection of minute mechanical changes.
• Full Electrical Isolation: Galvanic isolation between input channels and system backplane for superior noise immunity and equipment protection.
• Configurable Alarm Logic: On-board alarm processing with user-definable setpoints, providing independent alarm, danger, and shutdown relay outputs.
• Advanced Signal Conditioning: Built-in filtering, amplification, and linearization for optimal signal accuracy across a broad frequency spectrum (up to 50 kHz).
• Standard Rack Mounting: Designed for seamless integration into standard industrial monitoring racks, supporting hot-swappable installation.
• LED Diagnostic Indicators: Front-panel LEDs for power, channel status, and alarm conditions to facilitate rapid system diagnostics.
• Wide Environmental Tolerance: Operates reliably under extreme temperatures and harsh industrial conditions with high resistance to vibration and shock.
• Low Power Consumption: Energy-efficient design (typical 7.7W) suitable for continuous, long-term operation.
• Industry Standard Compliance: Fully compliant with global industrial safety, EMC, and environmental standards.
