Transient and RFI Interference
This section describes transient and RFI interference precautions:
• Although there are transient and noise protectors on all sensor unit
I/O connections (communications, current outputs, sensor, etc.), this
protection is intended to act as a last line of defense against unwanted
transient and RFI interference.
• Proper installation practices to prevent the introduction of transients
and noise into the system must be followed. Inductive loads connect-
ed to the sensor unit must have transient suppressors installed at the
inductive loads. Be sure to place the transient suppressor as close to
the load as possible. Examples of transient suppressors include MOVs,
TRANSORBs, and RC snubbers.
