The optocoupler provides bidirectional current sensing via two antiparallel GaAs infrared emitting diodes. S 1 2 .268 (6.81) .255 (6.48) AGENCY APPROVALS The LH1528 Telecom switches consist of an optically coupled solid state relay (SSR) Form B, and a bidirectional input optocoupler. The SSR is ideal for performing switchhook and dial-pulse switching while the optocoupler performs ring detection and loop current sensing functions. Both the SSR and optocoupler provide 5300 VRMS of input to output isolation. 3 4° typ. .050 (1.27) typ. .031 (.79) typ. .150 (3.81) .130 (3.30) Radius .008 (.25) .004 (.10) .040 (1.02) .020 (.51) .100 (2.54) typ. .395 (10.03) .375 (9.52) .312 (7.80) .298 (7.52) 10° .315 (8.00) typ. 3° to 7° .010 (2.54) typ.
