163179-01 Bently Nevada 3500/60 Temperature Modules I/O Four Channels

I. Product Overview
The 163179-01 is a factory-installed I/O module for the Bently Nevada 3500 Series 3500/42M Prox/Seismic Monitor. It provides four independent channels for simultaneous connection of eddy-current displacement sensors and acceleration/velocity sensors, providing critical mechanical protection parameters for rotating machinery, such as shaft vibration, housing vibration, eccentricity, and thrust. This plug-and-play module seamlessly integrates with the 3500 frame, TDI communications processor, and System 1 software. It is a core component for condition monitoring and predictive maintenance of turbines, compressors, fans, and pumps in industries such as power plants, petrochemicals, metallurgy, and papermaking.

II. Key Selling Points
1. Four-Channel "Two-in-One" Design
• Any channel can be software-configured to measure 11 types of measurements, including radial vibration, axial displacement, acceleration, velocity, eccentricity, and differential expansion. • Reduce spare parts variety and inventory by over 30%.

2. Complies with the latest API 670 standard
• Linearity ≤±0.5%, repeatability ≤±0.2%, and a frequency response of 0.5 Hz–10 kHz, ensuring high-reliability protection for the unit.
• Built-in OK detection and self-test circuitry provides an alarm within 2 seconds for sensor disconnection or short circuit, preventing nuisance trips.

3. Hot-swappable & redundant power supply
• Online replacement without downtime, with a mean-time-to-test (MTTR) of less than 5 minutes; dual power supply redundancy ensures 99.999% availability.

4. Seamless integration with Industry 4.0
• Native support for Ethernet Modbus/TCP, OPC UA, and IEC 61850, enabling direct integration with DCS, PLCs, MES, and cloud platforms.
• One-click upgrade of AI diagnostic models via System 1 Edge enables early prediction of faults such as bearing wear and shaft cracks.
