FAQ

1. What types of sensors are supported by the 3500/60 I/O Module?

   It supports RTDs (2-, 3-, and 4-wire) and multiple thermocouple types (J, K, E, T, B, R, S, N).

2. How does the internal barrier function improve safety?

   The barrier limits voltage and current to intrinsically safe levels, preventing ignition in hazardous areas.

3. Can this module be used in both safe and hazardous zones?

   Yes, it is designed for intrinsic safety applications but can also be used in non-hazardous environments.

4. How many channels does the 3500/60 Temperature Monitor support through this module?

   Typically, up to 12 RTD or thermocouple inputs can be connected per monitor.

5. Does the I/O module provide galvanic isolation?

   Yes, it provides isolation between the field wiring and the rack electronics.

6. Can the module detect open or shorted sensors?

   Yes, diagnostic functions detect sensor failures and generate system alarms.

7. Is the I/O module hot-swappable?

   Yes, it can be replaced without powering down the rack, reducing downtime.

8. What kind of diagnostic data does it provide?

   It continuously monitors input channels and reports wiring faults, sensor errors, and barrier issues.

9. Does the I/O module require external barriers?

   No, because internal barriers are integrated, eliminating the need for separate barrier assemblies.

10. How does it interface with System 1 software?

    The I/O module works with the 3500/60 Monitor, which communicates data to System 1 for condition monitoring.
