Transient protection terminal block grounding
The transmitter can withstand electrical transients of the energy level usually encountered in
static discharges or induced switching transients. However, high-energy transients, such as
those induced in wiring from nearby lightning strikes, can damage the transmitter.
The transient protection terminal block can be ordered as an installed option (Option Code T1)
or as a spare part to retrofit existing Rosemount 2088 transmitters in the field. See
on page 171
