🔹 Product Introduction
The Bently Nevada 3500/61 163179-02F is a six-channel Temperature Monitor module for the 3500 Machinery Condition Monitoring System. It accepts RTD and thermocouple temperature inputs, conditions the signals, and compares measured temperatures with user-programmable alarm setpoints. Unlike the 3500/60, the 3500/61 provides individual recorder outputs for its six channels, making it suitable for temperature trending and connection to external monitoring or control systems. Typical applications include bearing temperature monitoring, generator winding temperature monitoring, turbine and compressor monitoring, and other rotating machinery protection applications.

The 3500/61 accepts 1 to 6 RTD or thermocouple transducer signals and provides six recorder outputs. The recorder outputs are proportional 4–20 mA signals, with a specified voltage compliance of 0 to +12 VDC across a 0–600 Ω load. The module uses a full-height front slot in the 3500 rack and a corresponding rear I/O module.
🔧 Troubleshooting & Common Issues
• If a temperature channel shows an incorrect or unstable value, inspect the RTD or thermocouple wiring, sensor condition, terminals, and I/O module.
• If one channel is unavailable, verify that the corresponding sensor and channel wiring are correctly connected.
• Check the 3500 rack power supply and backplane connections if the module does not start normally.
• If the recorder output is abnormal, verify the 4–20 mA loop wiring and connected DCS/PLC analog input.
• Check the OK, TX/RX, and Bypass LEDs when diagnosing module status and communication conditions.
• Confirm that the correct RTD or TC configuration has been programmed through the 3500 Rack Configuration Software.
• Do not replace the monitor before checking the sensor, I/O module, terminal connections, and rack configuration.
⚠️ Safety Precautions
• Isolate the machinery and electrical power before removing or installing the module.
• Follow the site’s lockout/tagout procedures before working on the monitoring system.
• Use suitable ESD protection when handling the electronic module.
• Verify sensor wiring and polarity before energizing the system.
• Do not connect or disconnect field wiring while the associated equipment is energized unless the approved maintenance procedure specifically permits it.
• Confirm that the replacement module and I/O configuration match the existing 3500 rack.
• Perform appropriate functional and alarm checks before returning the monitored machinery to normal operation.
📰 Product-Related News & Industry Context
The Bently Nevada 3500/60 and 3500/61 family is designed for six-channel temperature monitoring in machinery condition-monitoring systems. The 3500/61 adds individual recorder outputs for each channel, allowing temperature information to be passed to external recording or control equipment. The family supports RTD and thermocouple measurements, programmable alarm setpoints, and different I/O configurations including non-isolated RTD/TC and isolated thermocouple versions.
The 3500/61 can also be used in Triple Modular Redundant configurations. In TMR applications, temperature monitors are installed as groups of three so the system can use voting functions to improve fault tolerance.
❓ Q&A
Q: What is the Bently Nevada 3500/61?
A: It is a six-channel temperature monitoring module for the Bently Nevada 3500 machinery monitoring system.

Q: How many temperature channels are available?
A: The module provides six independent temperature monitoring channels.
Q: What is the difference between 3500/60 and 3500/61?
A: Both provide six-channel RTD/TC temperature monitoring, while the 3500/61 additionally provides recorder outputs for each of its six channels.
Q: What is the recorder output?
A: The 3500/61 provides individual 4–20 mA recorder outputs for its six channels.
Q: What is the approximate power consumption?
A: Published specifications list nominal consumption of approximately 9 watts.
Q: What I/O module is associated with 163179-02?
A: Depending on the system configuration, compatible I/O options include RTD/TC non-isolated and TC isolated modules. Part number 133819-02 is listed as an RTD/TC non-isolated I/O module with internal terminations.
Q: Is 163179-02F the same as 163179-02?
A: The supplied listing identifies the item as 163179-02F. Because suffixes can identify revisions or configurations, the physical label, revision, and associated I/O module should be checked before treating it as interchangeable with another 163179-02 unit.
