Hoʻohana ʻia ka interface coaxial BNC maʻamau no ka pale uila o ka ʻōnaehana kiaʻi wikiō coaxial SD.

ʻO ka Network SPD (Surge Protective Device) kahi mea i hoʻohana ʻia e pale i nā ʻōnaehana kelepona mai nā pilikia uila e like me nā voltages koke, nā surges, a me nā hahau uila. Hoʻokomo pinepine ʻia lākou ma ka hopena hoʻokomo o nā laina kelepona e pale aku i ka hōʻino ʻana o ka overvoltage i nā lako a i ʻole nā ​​​​ʻōnaehana koʻikoʻi.

ʻO ka ʻōnaehana kelepona e komo pū ana me nā laina kelepona, nā laina ʻikepili, nā laina pūnaewele, a me nā mea ʻē aʻe, kahi e kū pinepine ai i nā hoʻoweliweli mai nā pōʻino kūlohelohe e like me ka uila, a no laila e pono ai nā hana palekana kūpono. ʻO ka hana o ka SPD pūnaewele ke alakaʻi i ka uila koke i hoʻokomo ʻia i loko o ka ʻōnaehana kelepona i ka honua ke hiki i kahi pae weliweli, i mea e pale ai i nā lako mai ka hōʻino ʻia.

I ke kau ʻana i ka SPD pūnaewele, he mea nui e koho i nā huahana i kūpono no nā ʻano o ka laina kelepona a hahai i nā kuhikuhi a ka mea hana no ke kau pono ʻana. Hiki i kēia ke hōʻoia i ka hiki i ka ʻōnaehana kelepona ke pale pono i nā lako i nā hanana koke e like me ka uila, e hōʻoia ana i ke kūpaʻa a me ka hilinaʻi o ke kamaʻilio ʻana.

ʻO ka maʻamau, loaʻa i ka SPD Pūnaewele kahi interface RJ45 maʻamau, kahi kūpono no ka hoʻopili ʻana i nā laina pūnaewele i nā kuapo, nā wahi hana, a me nā mea kamaʻilio pūnaewele like ʻole. Ke komo nā mea hoʻopilikia uila e like me ke voltage koke a i ʻole nā ​​​​​​kuʻi uila i ka laina pūnaewele, kuhikuhi koke ka SPD pūnaewele i kēia mau mea hoʻopilikia i ka honua e pale i nā mea i pili i ka pūnaewele mai ka hōʻino ʻia.

I ke kau ʻana i kahi SPD pūnaewele, hoʻokomo pinepine ʻia ia i loko o ka hoʻokomo o ka laina pūnaewele e pale aku i ka overvoltage mai ka laha ʻana ma o ka laina pūnaewele i nā mea i hoʻopili ʻia. Hiki i kēia ke hōʻoia i ka palekana pono o nā lako pūnaewele i nā hanana koke e like me ka uila, a hoʻomaikaʻi i ke kūpaʻa a me ka hilinaʻi o ka pūnaewele.

ʻO ka moʻo PHL-S SPD kahi mea i hoʻolālā kūikawā ʻia e pale i nā lako kahua e like me nā mea hoʻoili, nā kuapo, nā hōʻailona alapine (frequency), nā lako kamaʻilio, TC, RTD, a pēlā aku. Hiki ke hoʻopili ʻia i ka I/O, DCS, PLC a me nā lako ʻē aʻe i loko o ka lumi hoʻomalu, kahi i hoʻopili pinepine ʻia me ka hoʻohana ʻana i ʻelua uea a me ʻekolu ʻōnaehana uea. No laila, pono ka palekana pono e pale aku i ka hopena o ka uila impulse voltage a i ʻole ka hana over-voltage.
