The Ovation System imagwiritsa ntchito njira zitatu zokanira phokoso zogwirizanitsa makina amtundu wa digito: • Kusefa kwapansi kochepa • Miyezo ya zizindikiro zazikulu (48 VDC kapena 115 VAC) • Kudzipatula kapena kugwirizanitsa kuwala Kusefa kwapang'onopang'ono ndi kugwiritsa ntchito njira zazikulu zamtundu wa zizindikiro zimapereka tsankho pafupipafupi ndi mphamvu, motsatira. Kudzipatula kwa cholandirira ma siginecha a digito kuchokera pansi ndikofunikira ngati njira yokanira phokoso lomwe limapangitsa kuti mawaya onse awiri azitha kusintha mphamvu yamagetsi kupita pansi. Chitsanzo cha kudzipatula kwamtunduwu ndi gwero lazizindikiro (transmitter) yomwe imakhazikika pamalo akutali ndi wolandila, pomwe ma transmitter ndi olandila sali pamagetsi omwewo. Pankhaniyi, kusiyana komwe kungachitike pansi kumawoneka ngati voteji pamawaya onse amtundu wofananira. Chitsanzo china chomwe kudzipatula kungafunikire kukana phokoso la kusiyana komwe kungachitike kungakhale m'mabwalo omwe kulumikizana kuli pakati pa mawaya ozindikira, kupangitsa kuti mawaya onse awiri azitha. Kuthekera kopangitsidwa kumatha kuchitika ngati mawaya a siginecha alipo m'malo omwe amasintha ma elekitirodi kapena ma electrostatic. Kudzipatula kungafunike pamenepa. Optical isolator (yomwe imadziwikanso kuti opto-isolator) ingagwiritsidwe ntchito kubweretsa ma sign a digito mu wolandila. Palibe kuyankha kwa wolandila kuphokoso komwe kungachitike pokhapokha ngati phokoso la mzere wa sigino likuyenda. Mafupipafupi otsika, omwe amatha kuyenda chifukwa cha mphamvu zofanana za phokoso-to-ground pa mawaya onse amtundu wa chizindikiro, amachotsedwa ngati mawaya a siginecha sazikika pa mfundo imodzi. Izi zimatchedwa kuti common-mode voltage.
