Deltapilot S
Endress+Hauser 9
Communication protocol • 4 to 20 mA with HART communication protocol
•PROFIBUS PA
– The Endress+Hauser Deltapilot S devices meet the FISCO model requirements.
– Due to the low current consumption of 10 ± 1 mA, the following can be operated at one bus segment
with installation as per FISCO:
– Up to 9 Deltapilot S for EEx ia, CSA IS and FM IS applications
– Up to 32 Deltapilot S for all other applications, e.g. in non-hazardous areas, EEx nA, etc.
Further information on PROFIBUS PA can be found in Operating Instructions BA034S "PROFIBUS DP/PA:
Guidelines for planning and commissioning" and in the PNO guideline.
• FOUNDATION Fieldbus
– The Endress+Hauser Deltapilot S devices meet the FISCO model requirements.
– Due to the low current consumption of 11 ± 1 mA, the following can be operated at one bus segment
with installation as per FISCO:
– Up to 9 Deltapilot S for EEx ia, CSA IS and FM IS applications
– Up to 32 Deltapilot S for all other applications, e.g. in non-hazardous areas, EEx nA, etc.

Measuring system Measuring system with 0.2 to 1.2 mA analog – FEB11(P)
The electronic insert returns a current signal of 0.2 to 1.2 mA that is in proportion to the pressure. The
FMC420 silometer provides voltage to the electronic insert and evaluates the current signal that is in proportion
to the level. The standardized signals of 0 to 10 V and 4 to 20 mA (0 to 20 mA) are then available at the output
of the silometer. → See also Technical Information TI077F and Operating Instructions BA179F.
Measuring system with PFM – FEB17(P)
The electronic insert returns a pulse-frequency-modulated signal of 200 to 1200 Hz. The evaluation and
operating unit Prolevel FMB662 provides power to the electronic insert and converts the PFM signal of the
probe to a standardized current or voltage signal. → See also Technical Information TI234F and Operating
Instructions BA144F.
Measuring system with 4 to 20 mA HART – FEB22(P)
HART is a field-tested industry standard accepted worldwide. In HART technology, the 4 to 20 mA analog
transmission and the digital communication take place simultaneously via the same wire pair. The 4 to 20 mA
analog signal is used for rapid measured value transmission. The digital HART signal allows device data to be
read and written, e.g. for diagnosis and maintenance information.
Measuring system with PROFIBUS PA – FEB24(P)
PROFIBUS PA is an open fieldbus standard. It allows multiple sensors and actuators to be connected, even in
Ex-areas. By means of PROFIBUS PA, energy is supplied to the devices with two-wire technology and the
process information is transmitted digitally from the sensor.
Further information on PROFIBUS PA, such as bus system component requirements, can be found in Operating
Instructions BA034S "PROFIBUS DP/PA: Guidelines for planning and commissioning" and in the PNO
guideline.
Measuring system with FOUNDATION Fieldbus – FEB26
FOUNDATION Fieldbus is an open fieldbus standard. It allows multiple sensors and actuators to be connected,
even in Ex-areas. By means of FOUNDATION Fieldbus, energy is supplied to the devices with two-wire
technology and the process information is transmitted digitally from the sensor.
