FISCO model

As a result of current - and voltage - limitations required, and in case of classic Ex i-engineering (see Section 6.9.5), some restrictions are imposed upon the intrinsically safe variant. The number of field devices to be connected to the bus system is limited to approximately five, in particular in case of a current consumption exceeding the designated value of 10 mA. Besides, the length of cables shall be limited to some 100 m due to capacitance and inductance limitations. Away out is demonstrated below (FISCO model, see Section 6.9.6). [Pg.380]

The boundary conditions for the FISCO model are summarized as follows (see Fig. 6.235) ... [Pg.411]

The further development of the FISCO model will be incorporated into international standardization as IEC 60079-27 Electrical apparatus for explosive gas atmospheres, FISCO-Concept for HI intrinsically safe Fieldbus systems. In this standard, the safety-related data will be specified in detail ... [Pg.413]
