Product Description The Bently Nevada 3500/61 163179-01G is a 6-channel temperature monitoring module used within the 3500 Series Machinery Protection System. This specific PWA (Printed Wiring Assembly) is the core hardware component that accepts inputs from various temperature sensors to provide continuous machinery protection. Unlike the 3500/61 (isolated version), the 3500/60 is a non-isolated monitor, making it a cost-effective solution for environments where channel-to-channel isolation is not required. The “Revision G” indicates a hardware update that maintains high accuracy and reliability for long-term industrial deployment. It provides both “Alert” and “Danger” alarm setpoints for each channel, ensuring early detection of thermal anomalies in rotating equipment.

Application Areas This module is primarily used for monitoring non-critical and semi-critical machinery temperatures. Common applications include monitoring bearing temperatures in pumps and motors, casing temperatures on compressors, and various process temperature points in manufacturing plants. It is a staple in power generation, water treatment, and general industrial automation where thermal trending is required for predictive maintenance.

Operational Precautions

• Grounding: Since this is a non-isolated module, ensure that all sensors share a common ground reference to prevent ground loop interference that could skew temperature readings.
• I/O Modules: This PWA must be paired with the correct 3500/60 I/O module (either the Internal Termination or External Termination version) located at the rear of the rack.
• Cold Junction Compensation: For Thermocouple applications, ensure the I/O module is properly installed to allow the Cold Junction Compensation (CJC) sensor to accurately track the terminal temperature.
• Software Configuration: Use the 3500 Rack Configuration Software to set the specific RTD type (e.g., Pt100) or TC type (e.g., Type K) for each individual channel before commissioning.
