SINEAX 2I1Passive DC Signal Isolatorwithout power supply0102II (1) G resp. II (2) GApplicationThe DC signal isolator SINEAX 2I1 (Fig. 1) serve to isolate loadindependentDC current signals. It suppressed noise voltagesand currents in a signal loop circuit.Features / Benefits● Electrically insulated between input and output / Prevents the transferof interference voltages and currents, overcomes signal connectionproblems● Input signal : Output signal = 1 : 1● No power supply required / No additional wiring and no power supplyunit● Immune to transient voltages● Single-channel● Available in type of protection “Intrinsic safety” [EEx ib] IIC(see “Table 2: Data on explosion protection”)Fig. 1. SINEAX 2I1 in housing N for rail or wall mounting.Layout and mode of operationThe DC signal isolator comprises a DC chopper Z, an isolatingstage T, a rectifi er G and a multivibrator M (see Fig. 2). The DCchopper converts the load independent DC signal into an ACsignal. This signal is passed through a ferrite-core transformerserving as an isolating stage. On the secondary side, it is rectifi ed,smoothed and converted into a load-independent DC signal.The chopper unit is controlled by a specially designed multivibratorwhich obtains its power from the input signal.I EU EZMT G I AU VU A R extTechnical dataGeneralMTBF:Input signal EInput current (I E):Max. input voltage:Permissible input ripple: ≤ 10%Voltage loss U Vacrosssignal isolator:Approx. 120 000 h per isolatorLoad-independent DC current0 to 5 mA to 0 to 20 mA,4 to 20 mA(all ranges are possible with the sametype)U E≤ 15 V (see “Application example,Fig. 10, page 4)– non-intrinsically safe versionapprox. 3 V– intrinsically safe versionapprox. 6 VFig. 2.
