Note
• Terminals 42 / 52 have common grounding. Digital outputs
41 / 42 and 51 / 52 are not electrically isolated from each
other. An electrically isolated digital output can be made
using a plug-in module.
• If using a mechanical counter, it is advisable to set a pulse
width of
≥
30 ms and a maximum frequency of fmax
≤
3 kHz.
Current output V1 / V2, V3 / V4 (plug-in module)
Up to two additional plug-in modules can be implemented via
the ‘Passive current output (red)’ option module.
Can be configured for outputting mass flow, volume flow,
density and temperature via on-site software.
