Description
The 3500/61 is a six-channel temperature monitor for the 3500 rack. It accepts RTDs and thermocouples, compares temperature with Alert and Danger setpoints and provides a 4–20 mA output per channel, which is what distinguishes it from the 3500/60.
I/O modules come as non-isolated RTD/TC (RTD, TC or a mix) and isolated TC with 250 Vdc channel-to-channel isolation. The typical job is journal and thrust bearing temperature on turbines, compressors and pumps.
Specifications (datasheet 141540)
| Parameter | Value |
|---|---|
| Channels | 6 channels |
| Inputs | RTD or thermocouples (E, J, K, T), mixed on the non-isolated I/O |
| Outputs | 4–20 mA per channel (unlike the 3500/60), relays via 3500/32M/33 |
| Isolation | TC isolated version: 250 Vdc channel-to-channel |

10 Equipment Maintenance Strategies That Cut Downtime in 2026
10 maintenance strategies that genuinely reduce downtime in 2026: predictive maintenance, RCM, TPM, and tools like Artesis e-MCM and SDT340, with KPIs you can roll out in stages at plants across Kazakhstan.

Shaft Misalignment: the Hidden Killer of Bearings, Couplings and Seals
Up to half of all rotating equipment failures are linked to shaft misalignment. We break down the types of misalignment, its consequences, and how vibration analysis and current analysis detect it before it destroys couplings and bearings.

What an Hour of Downtime Really Costs and How to Cut Unplanned Stops
Unplanned downtime costs far more than the repair crew's payroll line suggests. We break down the full cost-of-downtime formula and show how switching to predictive maintenance cuts unplanned stops by 30–50%.

4 Stages of Bearing Failure: How to Catch a Defect Months Before It Fails
A bearing doesn't fail instantly — it goes through 4 stages of degradation, and the first one is only visible to ultrasound. We break down the P-F curve and which diagnostic method works at each stage of bearing failure.

The Mysterious 0.6× Frequency — a Frequency That Shouldn't Exist (But Does)
A peak at 0.6× in the spectrum isn't always BPFO. A thought experiment on changing reference frames, and how to confirm the hypothesis with SDT340 ultrasound and Artesis electrical signatures.

Gearbox Diagnostics: Tooth Wear, Pitting and Misalignment Before Shutdown
How to catch gear tooth wear, pitting and misalignment before an emergency stop. SDT 340 ultrasound walkdowns plus Artesis e-MCM on the drive motor — field experience from mining and metallurgy in Kazakhstan.
