Note!
By using the selection and planning program “Applicator”, you can determine the exact values for
the fluid you use. You can obtain the Applicator from your Hauser sales center or on the
Internet under www.endress.com.

Output
Output signal
Current output:
• 4...20 mA with HART
• Full scale value and time constant (0...100 s) can be set
Pulse/status output:
Open collector, passive, galvanically isolated
• Non-Ex, EEx d - version:
U
max
= 36 V, with 15 mA current limiting, R
i
= 500
Ω
• Ex i and Ex n version:
U
max
= 30 V, with 15 mA current limiting, R
i
= 500
Ω
The pulse/status output can be configured as:
• Pulse output:
– Pulse value and pulse polarity can be selected (5... 2,000 ms),
– Pulse width can be configured (0.005...2s)
– Pulse frequency max. 100 Hz
• Status output:
Can be configured for error messages or flow limit values
• Vortex frequency:
– Unscaled vortex pulses directly output 0.5...2,850 Hz (e.g. for connecting to a flow computer
RMC 621)
– Pulse ratio 1:1
• PFM signal (pulse/frequency modulation):
for external connection with flow computer RMC or RMS 621
