• Oil temperature in lube systems
• Zone 2 hazardous areas (refineries, chemical plants)

Frequently Asked Questions (FAQ)

Q1: Can I mix RTD and TC sensors on the same 3500/60-01-02?

Yes. Each channel works independently. You can connect RTD on channel 1 and TC on channel 2.

Q2: What is the difference between -01 and other I/O types?

The -01 is non-isolated with internal terminations. It works with standard 3500 racks. No external termination panel needed.

Q3: How to use external barriers with this monitor?

For hazardous areas, add external barriers between sensor and monitor. Then RTD range may be limited (see -50°C to +260°C for some types).

Q4: What happens if recorder output short circuits?

Nothing. Monitor continues normal operation. Recorder outputs are short-circuit protected by design.

Q5: Can I get this monitor shipped urgently?

Yes. We ship within 12-24 hours. Choose FedEx Priority, UPS Worldwide, or DHL Express. Tracking provided.

Buying Guidance – Field Experience

Order 3500/60-01-02 when you need Zone 2 approval and mix of RTD/TC. For isolated channels, pick other I/O types. Keep one spare module per 6 installed. Verify your rack firmware supports 3500/60 series.
