Professional FAQ
How many sensors can one module handle?
Up to six RTD or thermocouple inputs per monitor.
Is isolation always required?
No. Isolation is for fault cases, not normal operation.
Which RTD type is best for most plants?
100Ω platinum RTD (α 0.00385) is the industry standard.
Can recorder outputs be shorted?
Yes. Short circuits do not affect monitor operation.
What should buyers confirm before ordering?
Sensor type, channel count, and hazardous area needs.
