Specifications and Reference Data
Custom alarm and saturation level
Custom factory configuration of alarm and saturation level is available with option code C1 for
valid values. These values can also be configured in the field using a Field Communicator.
Turn-on time
Performance within specifications in less than 6.0 seconds after power is applied, when
damping value is set to 0 seconds.
External transient protection
The Rosemount 470 prevents damage from transients induced by lightning, welding, or heavy
electrical equipment. For more information, refer to the 470 Product Data Sheet (document
number 00813-0100-4191).
Integral transient protection (option code T1)
The transient protector helps to prevent damage to the transmitter from transients induced on
the loop wiring by lightning, welding, heavy electrical equipment, or switch gears. The transient
protection electronics are contained in an add-on assembly that attaches to the standard
transmitter device face. The external ground lug assembly (code G1) is included with the
Transient Protector. The transient protector has been tested per the following standard:
IEEE C62.41-1991 (IEEE 587)/ Location Categories B3.
6kV/3kA peak (1.2 50 Ωs Wave 8 20 Ωs Combination Wave)
6kV/0.5kA peak (100 kHz Ring Wave) EFT, 4kVpeak, 2.5kHz,
5*50nS
Loop resistance added by protector: 22 ohms max.
Nominal clamping voltages: 90 V (common mode), 77 V (normal mode)
