・ Sensor(s) are of a passive type to be regarded as ‘simple apparatus’.
・ Electrical data of the SC202S.
- Supply and output circuit (terminals + and -):
Maximum input voltage U
i
= 31.5 V. Maximum input current I
i
= 100 mA.
Maximum input power P
i
= 1.2 W.
Effective internal capacitance C
i
= 22 nF.
Effective internal inductance L
i
= 35 PH.
- Sensor input circuit (terminals 11 through 16):
Maximum output voltage U
o
= 14.4 V. Maximum output current I
o
= 13 mA.
Maximum allowed external capacitance Co = 59 nF (for SC202S-A),
Co = 2.9 uF (for SC202S-N).
Maximum allowed external inductance Lo = 200 mH (for SC202S-A),
Lo = 450 mH (for SC202S-N).
・ Barriers and power supply specification must not exceed the maximum values as
shown in the diagram above. These safety descriptions cover most of the commonly
used industry standard barriers, isolators and power supplies.
・ The Hand Held Communicator must be of a ATEX certified intrinsically safe type in
case it is used on the intrinsically safe circuit in the hazardous area or of a ATEX
certified non-incendive type in case it is used in the non-incendive circuit in the
hazardous area.
