FAQ

Q: What does suffix 01-01-01-00-00 mean?
A: 01 = 110–220V AC power (external supply); 01 = attached local display; 01 = DIN rail mounting; 00 = no approvals; 00 = no communication interface.

Q: What is the difference from 1900/65A-00-01-01-00-00?
A: This model (-01 power) uses 110/220V AC with external PSU; 00 power variant accepts direct 18–36VDC input.

Q: Is 1900/65A series still in production?
A: The 1900/65A series is still active by Bently Nevada (Baker Hughes). Original new units are available via authorized distributors.
