10.1.4 Output
Output signal Current output:
Active, galvanically isolated, full scale value selectable, temperature coefficient:
typically 2 µA/°C, resolution: 1.5 µA
• Active: 4...20 mA, R
L
< 700 Ω (for HART: R
L
≥ 250 Ω)
Pulse output:
Passive, open collector, 30 V DC, 250 mA, galvanically isolated.
Can be configured as:
– Pulse output:
Pulse value and pulse polarity can be selected, max. pulse width adjustable (5...2000
ms), pulse frequency max. 100 Hz
or
– Status output:
For example, can be configured for error message, Empty Pipe Detection, flow
recognition, limit value
Signal on alarm • Current output → Failsafe mode can be selected
• Pulse output → Failsafe mode can be selected
• Status output → “Not conductive” in the event of fault or power supply failure
Details → Page 71
Load See “Output signal”
Low flow cut off Switch-on point for low flow cut off can be selected as required
Galvanic isolation All circuits for inputs, outputs and power supply are galvanically isolated from each
other.
