Overview of MODIS modules

FA-ST B1, B1⊥ or B2, B2 ⊥
Pulse (frequency) output or status in-/output, all passive
The function can be set by software

DC-I I+, B1+
Intrinsically safe voltage source for the passive module
P-SA or FA-ST, so that active operation is possible.
U
o
= 23.5 V, I
o
= 98 mA, P
o
= 0.6 W
C
o
= 132 nF, L
o
= 4 mH
Note!
When modules P-SA (or FA-ST) and DC-I are connected
in series, the internal capacitance C
i
of 5 nF must be
subtracted from the C
o
of 132 nF. So the data plate will
list a C
o
of 127 nF.
Besides the shown intrinsically safe maximum values for voltages and current -which are based
on certain fault conditions as prescribed by the standard EN 50 020 - the nominal values for
current and voltage must also be respected otherwise a proper functioning of the modules is not
guaranteed!
