Compatible Replacement & Equivalent Models
The following models are functionally equivalent or direct replacements for the 3500/61-01-00 in temperature monitoring applications. Always verify rack firmware version and I/O module compatibility before substitution.
- Bently Nevada 3500/61-00-00 — Base variant without recorder output; suitable where 4–20 mA output is not required
- Bently Nevada 3500/61-02-00 — Enhanced variant with dual-channel recorder output
- Bently Nevada 3500/62-01-00 — Process variable monitor; compatible I/O footprint, broader input range
- Emerson CSI 6500 ATG — Next-generation platform; requires rack migration but offers expanded diagnostics
- Metrix ST5484E — Third-party equivalent for temperature/vibration monitoring; DIN-rail mount alternative
- Rockwell 1715-AENTR — Not a direct replacement; requires engineering re-design for SIL-rated applications
Note: Cross-brand substitutions require full I/O mapping review and system re-validation. Contact Konmask engineering support for assistance.

Selection Guide
Use the following criteria to confirm the correct model for your application:
- Step 1 — Input Type: Confirm sensor type (thermocouple J/K/T or RTD PT100/PT1000). The -01-00 suffix supports standard thermocouple inputs; verify I/O module 133819-02 matches your sensor wiring.
- Step 2 — Output Requirement: If 4–20 mA recorder output to DCS/historian is required, confirm -01-00 variant (recorder output enabled). Use -00-00 if output is not needed.
- Step 3 — Channel Count: Single module supports up to 4 channels. For higher channel density, consider multiple modules or the 3500/62 process monitor.
- Step 4 — Rack Slot Availability: Verify available slots in your 3500 rack. Each 3500/61 occupies 2 adjacent slots (monitor + I/O module).
- Step 5 — Firmware Version: Confirm rack firmware v3.x or above for full feature support. Contact Konmask if firmware version is unknown.

Replacement & Compatibility FAQ
Q: Can I use the 3500/61-00-00 instead of the 3500/61-01-00?
A: Yes, if you do not require the 4–20 mA recorder output. The -00-00 variant is functionally identical for temperature measurement but omits the analog output channel.
Q: Is the 133819-02 I/O module interchangeable with other 3500/61 I/O modules?
A: The 133819-02 is specific to thermocouple input configurations. RTD applications require a different I/O module. Verify your sensor type before ordering.
Q: Will this module work in a 3300 Series rack?
A: No. The 3500 and 3300 series use incompatible backplane architectures. The 3500/61 is exclusively for 3500 Series racks.
Q: Can Konmask provide a functional test certificate?
A: Yes. Pre-shipment functional testing with a written test report is available upon request at no additional charge for orders above 2 units.
Q: What is the lead time for this module?
A: In-stock units ship within 3–5 business days. For out-of-stock items, typical lead time is 4–8 weeks. Contact us for current availability.
