Overview
The Bently Nevada 79532-01, also cataloged as the PWA 79532-01 RTD input terminal, provides the field termination interface for RTD temperature signals within the Bently Nevada 3300 Series machinery protection system. Available references associate this PWA with 82368-01 and 82369-01 terminal/module configurations; therefore, the installed assembly number should be verified before replacement.

Suffix Breakdown & Model Matrix
The supplied identification is 79532-01. The available documentation does not establish a manufacturer-defined suffix matrix for 79532 and 01, so these characters are not assigned separate functional meanings here.
References also associate 79532-01 with 82368-01 for 3-wire RTD input arrangements and 82369-01 for 4-wire RTD input arrangements. These associated assembly numbers should not be treated as interchangeable without checking the installed 3300 Series monitor configuration. (Machinio)

The available references identify 79532-01 as an RTD input terminal associated with the 3300 Series. They also distinguish 3-wire and 4-wire configurations through different associated assembly numbers. (DcsSupplier Limited)
RTD Signal Interface and Machinery Temperature Monitoring
The terminal assembly routes field RTD connections to the compatible 3300 Series temperature-monitoring hardware. In a 3-wire arrangement, the additional lead compensates for lead resistance at the measurement interface. In a 4-wire arrangement, separate excitation and sensing paths provide the connection required by the compatible measurement circuit.
Therefore, technicians should verify the RTD wiring method and the complete monitor assembly number before connecting field conductors. Do not substitute a 3-wire and 4-wire configuration solely because both references contain 79532-01. (DcsSupplier Limited)
Frequently Asked Questions
Q: Is 79532-01 itself a complete temperature monitor?
A: The available references identify 79532-01 as an RTD input terminal or associated terminal assembly. It should not be treated as a complete standalone temperature monitor.
Q: Can 82368-01 and 82369-01 be substituted directly?
A: No direct interchangeability should be assumed. References associate 82368-01 with a 3-wire RTD arrangement and 82369-01 with a 4-wire arrangement. Verify the installed monitor and wiring configuration first. (DcsSupplier Limited)
Q: Does the terminal require separate power?
A: The supplied information does not specify an independent power requirement for the terminal assembly. Power and measurement functions should be checked against the associated 3300 Series monitor.
Field Installation Guidelines
- Verify the complete assembly identification before installation, including 79532-01 and the associated 82368-01 or 82369-01 number where applicable.
- Confirm whether the installed RTD circuit uses 3-wire or 4-wire wiring.
- Isolate the relevant monitoring circuit before disconnecting field conductors.
- Maintain the original terminal-to-channel wiring assignment during replacement.
- Route RTD signal wiring separately from high-current power conductors and switching circuits where practical.
- Preserve cable shielding and connect the shield according to the installed 3300 Series system grounding scheme.
- Inspect terminal connections for loose conductors, damaged insulation, contamination, or corrosion before commissioning.
- Verify signal continuity and channel identification before returning the temperature-monitoring channel to service.
