The current / HART output can be operated in "active" or "passive" mode.
Active: 4 ... 20 mA, HART protocol (standard), load: 250 Ω ≤ R ≤ 650 Ω
A
Passive: 4 ... 20 mA, HART protocol (standard), load: 250 Ω ≤ R ≤ 650 Ω
B
Supply voltage for the current output: minimum 11 V, maximum 30 V.
For Ex zone 1 / Div. 1 the maximum load is 300 Ω.

The output can be configured as an "active (A)" or "passive (B)" output (in the case
of the transmitter with the dual-compartment housing, the output is configured
using the software; in the case of the transmitter with the single-compartment
housing, it is configured by means of jumpers on the transmitter backplane).
Configuration as "active" output:
U = 19 ... 21 V, Imax = 220 mA , fmax ≤ 5250 Hz
-
Configuration as "passive" output
Umax = 30 V, Imax = 220 mA, fmax ≤ 5250 Hz
-
Configuration as pulse output:
- Max. pulse frequency: 5250 Hz.
- Pulse width: 0.1 ... 2000 ms.
- The pulse factor and 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
