The OEM datasheet identifies 163179-01 specifically as the 3500/60 Temperature Monitor without recorders and lists the compatible I/O modules as 133827-01, 133819-01, 133835-01, 133843-01, and 136711-01.

One important procurement detail: the 163179-01 is the monitor module, not a universal standalone RTD/TC input assembly. The selected I/O module determines termination and isolation characteristics.

 

Application Scenarios & Pain Points

A temperature monitor normally gets noticed only after a channel starts generating nuisance alarms—or worse, fails to identify a genuine temperature excursion. In a rotating-machine protection rack, that distinction matters.

  • Turbine and compressor machinery: Six temperature channels can monitor bearing, winding, or other critical machine temperatures using appropriate RTDs or thermocouples.
  • Large rotating equipment: The 3500/60 can condition sensor inputs and compare them with user-programmable alarm setpoints, making it suitable for continuous machinery temperature protection.
  • Legacy 3500 rack maintenance: Particularly useful when replacing an existing 3500/60 monitor while retaining the installed field wiring and compatible I/O module.
  • TMR protection architectures: When temperature monitoring is configured for TMR, the monitors are installed as adjacent groups of three so the system can perform voting and reduce dependence on a single module.

Field note: If the replacement displays temperature but the alarm behavior does not match the original rack, stop there. Check the channel configuration and alarm setpoints before blaming the sensor. The physical module can be correct while the software configuration is wrong.

Related Products

  • Bently Nevada 3500/61 163179-02 — The closest functional counterpart. It provides the same six-channel temperature-monitoring function but adds recorder outputs for the six channels. Use the /61 when a 4–20 mA recorder interface is required; do not substitute it simply because the front-panel format looks similar.
  • Bently Nevada 133819-01 — 3500/60 RTD/TC non-isolated I/O module with internal terminations. It pairs with the 163179-01 when field wiring is intended for internal termination.
  • Bently Nevada 133827-01 — RTD/TC non-isolated I/O module with external terminations. Choose this arrangement where the installation requires external field termination.
  • Bently Nevada 133835-01 — TC isolated I/O module with internal terminations. Its 250 VDC channel-to-channel isolation makes it appropriate where thermocouple circuits require electrical isolation.
  • Bently Nevada 133843-01 — TC isolated I/O module with external terminations. Functionally related to 133835-01, but the termination arrangement differs.
  • Bently Nevada 136711-01 — RTD/TC I/O module with internal barriers and internal terminations. This configuration is intended for installations requiring the associated barrier arrangement.
  • Bently Nevada 3500/05 — 3500 system rack used to house the monitoring modules. The rack configuration, slot arrangement, and power architecture must be checked before replacing a monitor.
  • Bently Nevada 3500/22M 138607-01 — Rack interface module used elsewhere in the 3500 architecture. It is complementary system hardware, not a replacement for the 3500/60 temperature monitor.

 

The Engineer’s Guide: Field Pitfalls to Avoid

⚠️ Do not confuse 163179-01 with 163179-02.
The difference is functional: 163179-01 = 3500/60 without recorder outputs, while 163179-02 = 3500/61 with recorder outputs. If the DCS or recorder system depends on those outputs, the distinction is significant.

⚠️ Match the I/O module, not just the monitor.
The 163179-01 requires a compatible 3500/60 I/O module. Verify whether the existing installation uses 133819-01, 133827-01, 133835-01, 133843-01, or 136711-01. Internal versus external termination can determine whether the existing field wiring can be reused.

⚠️ Do not assume RTD and TC configurations are interchangeable.
The non-isolated RTD/TC version can be configured for RTDs, thermocouples, or a mixture, while the isolated version is intended for thermocouple inputs. Check the actual sensor wiring and configured channel type before commissioning.

Practical replacement sequence: Record the existing channel configuration → identify the I/O module → verify sensor type and wiring → confirm rack configuration → install the monitor → validate all six readings → test Alert/Danger setpoints and downstream relay logic.

 

Frequently Asked Questions (FAQ)

What is Bently Nevada 3500/60 163179-01 used for?

It is a six-channel temperature monitoring module in the Bently Nevada 3500 Machinery Protection System. It accepts temperature information from compatible RTD and thermocouple input modules, conditions the signals, and compares them against programmed alarm setpoints.

Does 3500/60 163179-01 include recorder outputs?

No. This is one of the defining differences between the 3500/60 and 3500/61. 163179-01 is the 3500/60 monitor without recorder outputs, while 163179-02 is the 3500/61 monitor with recorder outputs.

Can I replace a 3500/60 163179-01 without replacing the I/O module?

Usually, yes, if the existing I/O module is compatible and remains in good condition. The monitor and I/O module are separate components. Before installation, verify the I/O module part number, termination arrangement, isolation type, and sensor configuration.

Which I/O modules work with 163179-01?

The OEM datasheet identifies these 3500/60 options:

  • 133819-01 — RTD/TC non-isolated, internal termination
  • 133827-01 — RTD/TC non-isolated, external termination
  • 133835-01 — TC isolated, internal termination
  • 133843-01 — TC isolated, external termination
  • 136711-01 — RTD/TC with internal barriers and internal termination

What should I check when buying a refurbished 3500/60 163179-01?

Ask for more than a power-up test. For a machinery-protection application, request confirmation of the exact part number, hardware/firmware revision, six-channel operation, compatibility with the intended I/O module, configuration capability, and alarm/setpoint testing. Inspect the rear connector and card-edge contacts as well—no oxidation or bent contacts should be present.

Is 3500/61 163179-02 a direct replacement for 3500/60 163179-01?

Not as a blanket substitution. The two modules share the core temperature-monitoring function, but the 3500/61 adds recorder outputs. If the existing installation does not require those outputs, the /60 is the correct functional choice; if recorder outputs are part of the architecture, confirm the complete rack and termination arrangement before changing families.
