2
Current output (terminals 31 / 32)
The current output can be operated in "active" or "passive" mode.
•
Active: 4 ... 20 mA, HART Protocol (Standard), load: 250 Ω ≤ R ≤ 650 Ω
• Passive: 4 ... 20 mA, HART Protocol (Standard), load: 250 Ω ≤ R ≤ 650 Ω
Supply voltage for the current output: min. 17 V, max. 30 V
3
Digital output DO1 (terminals 51/52) (pulse output or digital output)
Function can be configured locally via software as "Pulse Output" or as "Digital Output". Factory setting is "Pulse Output".
The output can be configured as an "active" or "passive" output.
Configuration via software.
•
Configuration as pulse output.
max. pulse frequency: 5250 Hz.
Pulse width: 0,1 …. 2000 ms.
The pulse factor and the pulse width are interdependent and are calculated dynamically.
• Configuration as contact output
Function: System alarm, empty pipe alarm, max./min. alarm, flow direction signaling, other
• Configuration as "active" output

Digital input: (Terminals 81 / 82) (contact input)
Function configurable locally by software:
External zero return, external totalizer reset, external totalizer stop, other
Data for the optocoupler: 16 V ≤ U ≤ 30 V, Ri = 2 k

5
Digital output DO2 (terminals 41/42) (pulse output or digital output)
Function can be configured locally via software as "Pulse Output" or as "Digital Output".
Factory setting is "Digital Output", flow direction signaling.
The output is always a "passive" output (optocoupler).
