Compatible Replacement & Equivalent Models
When the original 3500/60 is unavailable, end-of-life, or cost-prohibitive, the following models are commonly evaluated as replacements or equivalents. Always verify electrical and software compatibility before substitution.
- Bently Nevada 3500/60-01-00 – Standard variant with thermocouple inputs; direct drop-in for most 3500 rack configurations.
- Bently Nevada 3500/60-02-00 – RTD-optimized variant; suitable when Pt100/Pt1000 sensors are exclusively used.
- Bently Nevada 3500/61 – Enhanced temperature monitor with additional channel density; backward-compatible in most rack layouts.
- Emerson CSI 6500 ATG Temperature Module – Emerson’s next-generation platform; requires rack and software migration but offers expanded diagnostics.
- Yokogawa DTSX / Temperature Transmitter Modules – Third-party alternative for non-SIL-critical applications; requires signal conditioning review.
- Honeywell FSC Temperature Input Module – Suitable for safety-system replacements where SIL 2 certification is required and rack migration is acceptable.
Note: Cross-brand replacements require engineering validation. Contact Konmask for compatibility assessment.

- Safety Systems: Integrates with Triconex, Hima, and other SIL-rated safety PLCs via hardwired relay outputs
Selection Guide
Use the following criteria to determine whether the 3500/60 or an alternative is the right choice for your application:
- Existing 3500 Rack Infrastructure: If your plant already operates a 3500 rack, the 3500/60 is the lowest-risk, lowest-cost solution — no rack, wiring, or software changes required.
- Sensor Type: Confirm whether your field sensors are thermocouples or RTDs. Select the -01 (TC) or -02 (RTD) variant accordingly, or use the universal variant if mixed inputs are present.
- Channel Count: The 3500/60 provides 6 channels. For higher channel density, evaluate the 3500/61 or a multi-module configuration.
- Safety Integrity Level: For SIL 2 applications, retain the original Bently Nevada module and validate the full safety loop. Third-party replacements require independent SIL assessment.
- Budget vs. Risk: OEM modules offer the lowest integration risk. Remanufactured or equivalent modules may reduce cost but require incoming inspection and calibration verification.
- End-of-Life Consideration: If the 3500/60 is approaching EOL in your plant lifecycle plan, evaluate migration to the Emerson CSI 6500 platform with a phased rack replacement strategy.

Replacement & Compatibility FAQ
Q: Can I use a 3500/61 as a direct replacement for the 3500/60?
A: In most cases, yes — the 3500/61 is backward-compatible with the 3500/60 slot position and wiring. However, firmware and RCS configuration updates are required. Verify with your system integrator before swapping.
Q: Is the 3500/60 still in production?
A: Bently Nevada (Baker Hughes) periodically updates the 3500 product line. Availability of new units depends on current production status. Konmask can supply new, refurbished, or surplus units — contact us for current stock.
Q: Can I mix thermocouple and RTD inputs on the same 3500/60 module?
A: This depends on the specific variant. The universal variant supports mixed inputs; the -01 and -02 variants are sensor-type specific. Check your module’s part number suffix.
Q: What is the lead time for a 3500/60?
A: Surplus and refurbished units typically ship within 3–7 business days. New OEM units may have lead times of 4–12 weeks depending on manufacturer availability.
Q: Do you provide calibration certificates with the module?
A: Yes. Calibration certificates are available upon request for refurbished and tested surplus units. New OEM units include manufacturer documentation.
Q: Can the 3500/60 integrate with a Siemens or ABB DCS?
A: Yes, via the 3500 rack’s communication gateway (3500/92 or 3500/93), which supports Modbus RTU/TCP — compatible with most major DCS platforms including Siemens PCS 7 and ABB 800xA.
