7. FAQ (10 Q&A)

1. Q: What kind of sensor input does model 3500/45 135137‑01 accept?
   A: It accepts a proximity probe or eddy‑current displacement sensor on its single input channel.

2. Q: What are the module’s dimensions and weight?
   A: Approximately 160 mm × 100 mm × 25 mm, weighing about 0.45 kg.

3. Q: What output signals are provided?
   A: It provides analog output (4‑20 mA or 0‑10 V) and can also deliver a relay or contact‑closure alarm output.

4. Q: How fast does it detect and respond to deviations?
   A: It responds with trip or alarm in 20 milliseconds or less once a threshold is exceeded.

5. Q: Can it endure harsh industrial environments?
   A: Yes. Designed for –20 °C to +70 °C, up to 95 % non‑condensing humidity, and rugged mechanical mounting.

6. Q: Does it include self‑test or diagnostics?
   A: Yes. It includes sensor integrity checks, a power‑up self test, and LED status light for operator diagnostics.

7. Q: Is redundancy built in?
   A: There is internal signal conditioning redundancy, but only one sensor input channel.

8. Q: How is it mounted?
   A: It fits a standard 19‑inch rack slot, held in by rack rails; designed for easy insertion and removal for maintenance.

9. Q: What power does it use?
   A: It is powered from a DC supply between 18 and 32 volts.

10. Q: What kinds of machinery can it protect?
    A: Shafted machines such as turbines, compressors, large pumps. Wherever proximity or displacement monitoring is essential to prevent damage or failure.
