英文翻譯
Q1. What is changing on both the HART 7 248 and 644 Rail mount transmitters?
- The Enhanced Rail mount 248 and 644 will use 4-20MA and Hart 7 protocol communications.
- Both units will meet RoHS compliance.
- CVD Sensor matching will be available via the C2 option, which improves accuracy by trimming the transmitter to a specific RTD calibration schedule.
- The form factor will be reduced to a thickness of 23.5 mm.
- An LED indicator will provide visibility to transmitter/sensor health.
Q2. What changes are unique to the HART 7 644 Rail mount transmitters?
- The 644 Rail mount will have SIL 2/3 certification available using the QT option code.
- The 644 will include a dual sensor input option available using the 644T option. The dual sensor functionality will allow for hot backup, sensor drift alert, and calculated output functionality.
Q3. What unit options are unavailable at launch?
- At launch SIL 2/3 certification will not be available. Product management will communicate launch date in the future.
Q4. How can Enhanced HART 7 248 and 644 Rail mount transmitters be ordered?
- Add the RK option for HART 7at the end of the model string.

- There is $0 list price adder for the RK option
- SIL 2/3, Dual Sensor, and CVD Matching options will have price adders
Q6. Where can I download the new versions of the DDs?
Q7. How long will legacy spare parts be available?
- Legacy spare parts will be available up until the end of life date for the transmitters.
Q8. How will warranty claims on legacy units be handled?

- Educate and convert to a HART 7 unit
- If the HR7 unit is unacceptable, a toggle code will be provided by product management upon review
Q11. What if a customer requires a non- hazardous area approved HART 7 unit prior to launch of those units?
- Explore using a legacy unit
- If HART 7 is required, use a hazardous area approved model as a substitute
Q12. When will SIL certified 644R/T HART 7 units be available?
- Product management will communicate when these products are available.
Q13. How long will legacy products be available?
