Output values Status and measured values
Input variables Remote control: measurement, calibration and regeneration of
the analysis function
Supported features • PROFIBUS DP (DP-V0, cyclic data exchange), baud rate: 9.6
kbit/s – 12 Mbit/s
• PROFIBUS device address configured via onsite operation or
PROFIBUS Service "Set_Slave_Add"
• GSD
14.3 Power supply
Supply voltage • 100 to 240 V AC (fuse must be replaced)
• 50 or 60 Hz
• Battery-free parameter backup
The analyzer is fitted with a fuse, T 1.25 A, for the 215 to 240 V AC voltage level. If
the analyzer is operated with 100 to 130 V AC, replace the fuse with the T 2.5 A fuse
supplied. The fuse is located in the cover of the electronics unit.
Power consumption 40 VA
