Under the entity evaluation concept, SITRANS LR200 has the following characteristics:
(input voltage) U
i
(input current) I
i
(input power) P
i
(internal capacitance) Ci
(internal inductance) Li
Entity Concept:
The Entity Concept allows interconnection of intrinsically safe apparatus to associated
apparatus not specifically examined in such combination. The criteria for interconnection is
that the voltage and current which intrinsically safe apparatus can receive and remain
intrinsically safe, considering faults, must be equal to or greater than the output voltage (Uo)
and output current (Io) levels which can be delivered by the associated apparatus, considering
faults and applicable factors.
In addition, the maximum unprotected capacitance (Ci) and Inductance (Li) of the intrinsically
safe apparatus, including interconnecting wiring, must be equal to or less than the
capacitance and inductance which can be safely connected to associated apparatus.
FISCO Concept
Under the FISCO evaluation concept, SITRANS LR200 has the following characteristics:
(input voltage) U

(input power) P
i
(internal capacitance) Ci
(internal inductance) Li
