Ho kenya dithibelo tsa polokeho tse arohaneng tsa H series backplane lehlakoreng la ho lemoha: PHD-22HF-2727, ho kenya le ho ntsha ha dijithale, ho kenya le ho ntsha ha di-dual le ho ntsha ha di-dual.
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.
