Endress+Hauser Proline Prowirl 72F - Signal on Alarm; Load; Low Flow Cut off; Galvanic Isolation

Proline Prowirl 72F, 72W, 73F, 73W
Endress+Hauser 9
Signal on alarm • Current output: error response can be selected (e.g. in accordance with NAMUR Recommendation NE 43)
• Pulse output: error response can be selected
• Status output: "not conducting" in event of fault (open circuit)
Load
A0001921
The area shaded gray refers to the permitted load (for HART: min. 250 Ω)
The load is calculated as follows:
R
B
Load, load resistance
U
S
Supply voltage: non-Ex = 12...36 V DC; Ex d = 15...36 V DC; Ex i and Ex n = 12...30 V DC
U
Kl
Terminal voltage: non-Ex = min. 12 V DC; Ex d = min. 15 V DC; Ex i and Ex n = min. 12 V DC
I
max
Output current (22.6 mA)
Low flow cut off Switch points for low flow cut off can be selected as required
Galvanic isolation All electrical connections are galvanically isolated from one another.
