Ho kenya dithibelo tsa polokeho tse arohaneng tsa H series backplane lehlakoreng la ho lemoha: PHD-11HF-27, ho kenya le ho ntsha ha dijithale, ho kenya le ho ntsha ha le le leng le ho ntsha ha le le leng.
Thibelo e arohaneng e ka fetola switch ya bohaufi le ho kenya ha kgokelo sebakeng se kotsi ho ba letshwao la kgokelo ya relay mme ya le fetisetsa sebakeng se sireletsehileng.
Relay ea tlhahiso e na le switch ea khetho ea boemo ba "ON/OFF". Ho phaella moo, ho na le pontšo ea alamo ea lets'oao la ho kenya potoloho e khuts'oane kapa ea potoloho e bulehileng, potoloho e fana ka matla bakeng sa sensor ea ho kenya.
Sehlahisoa sena se hloka phepelo ea motlakase e ikemetseng.
Sesupo sa boemo ba lets'oao se behiloe ka leseli le lefubelu le lesehla ho bontša boemo ba ts'ebetso ea relay ea tlhahiso, ha e le bakeng sa ho tšosa joale leseli le lefubelu, nakong ea ts'ebetso e tloaelehileng leseli le lesehla.
