Signal on alarm Current output
Failsafe mode selectable (for example, according to NAMUR Recommendation NE 43)
Pulse/frequency output
Failsafe mode selectable
Relay output
De-energized in the event of a fault or power supply failure
Modbus RS485
If a fault occurs, the value NaN (not a number) is output for the process variables.
Switch output Relay output
Normally closed (NC or break) or normally open (NO or make) contacts available

max. 30 V / 0.5 A AC; 60 V / 0.1 A DC, galvanically isolated.
Load See "Output signal"
Galvanic isolation All circuits for inputs, outputs, and power supply are galvanically isolated from each other.

Power consumption AC: <15 VA (including sensor)
DC: <15 W (including sensor)
Switch-on current
• max. 13.5 A (< 50 ms) at 24 V DC
• max. 3 A (< 5 ms) at 260 V AC
Power supply failure Lasting min. 1 power cycle:
• EEPROM or T-DAT saves measuring system data if power supply fails.
• S-DAT: exchangeable data storage chip which stores the data of the sensor (nominal diameter,
serial number, calibration factor, zero point, etc.)
Potential equalization No measures necessary.
