2.4.2 Electrical connections for IS.
For installation in classified areas it is necessary to foresee the use of certified associated
apparatuses (e.g. safety barriers), with output electrical characteristics compatible with
the maximum input parameters (ref. to Name-plate) of the certified SP200is positioner:
Electrical input parameter of SP200is
Circuit Ui(V) Ii (mA) Pi(mW) Ci(nF) Li(mH)
Supply 30 100 650 2 -
Switch 1&2 15 25 65 12 -
Retransmit 30 100 650 15 -
Evaluation of the system constituted by the associated apparatus, SP200is positioner
and connection cables must be done by experienced personnel only and must match the
requisite of the standard EN 60079-25 for intrinsically safe systems.
In Section 6 there is an example drawing of electrical connections for Intrinsically Safe
applications.
A drawing of the Name-plate is shown below
A copy of EC-Type ATEX Certificate is in 'Section 13 - Certification'.
