With each in/output module a certain in/output function can be realised, see following overview:
In/Output
module
Function Electrical data
P-SA passive current output Current: 4..20 mA
Working voltage: 8.. 30 V DC
Voltage drop: 8 V at 4 mA
FA-ST passive pulse/status output or
control input (selectable through
software options)
Working voltage: 6..30 V DC
Working current: < 110 mA
Voltage drop
in ON-state: < 2 V at 110 mA
Leakage current
in OFF-state: < 900 µA at 30 V
Control input
Input voltage LOW level: < 3 V
Input voltage HIGH level: > 7 V
Frequency range: 0.. 12 KHz
DC-I intrinsically safe voltage source,
to be used in combination with
modules P-SA and FA-ST
Voltage: 20 V DC
Maximum current: 30 mA
Internal resistance: 260 Ω
F-PA passive Fieldbus interface conform FISCO model
The functionality of the terminals for signal in/outputs is depending on the version of the
IFC090 i-EEx electronic-unit installed. Each version is equipped with a different pair of in/output
modules. Following versions are possible:
