Igalelo
Amagalelo oKhuseleko kwiNkqubo yoKhuseleko aya kuthi mhlawumbi aKhuphiswe amandla kumagalelo ohambo okanye amagalelo e-analog.

Amagalelo edijithali
I-De-enegize to trip inputs (edla ngokubizwa ngokuba yi-fail-safe) iya kusetyenziswa kuwo onke amagalelo okhuseleko edijithali. Inani leempawu zokubeka iliso zokhuseleko ezifunekayo kwipharamitha yokhuseleko nganye iya kuxhomekeka ngokukodwa kwinqanaba lengqibelelo yokhuseleko (ukuhlelwa kokhuseleko) olufunekayo ukuba luphunyezwe, umjikelezo wovavanyo lobungqina be-100% ofunekayo kunye nenqanaba lokuxilonga elikhoyo kwisixhobo sentsimi.
Onke amagalelo edijithali okhuseleko aya kudityaniswa kwikhadi leDigital Input Termination Card. Apho inqanaba lengqibelelo yokhuseleko lifuna ngaphezu kwesinye isivamvo sendawo esibeka iliso kwipharamitha yokhuseleko, nganye yezi zivamvo kufuneka ibe, apho kunokwenzeka, ifakwe iintambo ukwahlula amaKhadi okuNyekisa. Inxalenye ye-Simplex yekhadi lokuphelisa (umzekelo, i-fuses) kufuneka ithathelwe ingqalelo kuhlalutyo lokuthembeka njengenxalenye ye-loop yasendle.

IKhadi lokuNyekisa liya kudityaniswa ne-Triguard SC300E yeModyuli yokuNgena ngentambo yenkqubo eqhelekileyo edibanisa kwisokethi kwi-Hot Repair Adapter Card okanye i-chassis slot.
Ngokusebenzisa iadaptha yokulungisa eshushu ikhadi, apho ifuneka khona, kunye nesixhobo se-chassis backplane isidibanisi igalelo lomqondiso liqhagamshelwe kwindawo yokubeka i-digital input slot apho i-Digital Input Module iya kuba khona.
Zonke iindawo zokubeka i-chassis kwaye, apho kuyimfuneko, iindawo zokubeka iqabane lokulungisa ezishushu ezilungiselelwe iModyuli yokuNgena kweDijithali kufuneka nazo zibe nezitshixo zepolarization ezifakelwe kwaye ziqwalaselwe olu hlobo lwemodyuli njengoko kuchaziwe kwiModyuli kunye ne-Chassis Users Manual.
Apho inqanaba lengqibelelo yokhuseleko lifuna ukuba kusetyenziswe abenzi boluvo abahlukeneyo ukujonga iiparamitha zokhuseleko ezifanayo kufuneka zibunjwe ukuze zahlule iiModyuli zoNgeniso lweDijithali apho kunokwenzeka.

Amagalelo e-analog
Ii-analog transmitters zisetyenziselwa ukubeka esweni iiparamitha zokhuseleko kwaye ngokwemvelo zibonelele ngenqanaba elongezelelweyo lokuxilonga ngokubhekiselele kwigalelo elilula elingaphumeleliyo ledijithali. Iimpawu ze-analog zihlala zibonelela ngexabiso ngaphakathi koluhlu olusebenzayo. Kwiitransmitha ezinxulumene nokhuseleko oku kufuneka kube yi-4-20 mA okanye i-1-5 volts evumela ukubonakaliswa kwempazamo ngezantsi ithi 3 mA (0.75 V) kunye ne-20 mA (5 V). Ukuba ukubonwa okungaphezulu kuyafuneka, imodyuli yokufaka i-0-10 V kufuneka isetyenziswe. Zonke iimpazamo ezibekwe esweni kwiimpawu ze-analog kufuneka zisetyenziswe yisoftware yesicelo ukuvelisa iziphumo ezingaphumeleliyo (umzekelo, umthumeli ongaphumelelanga ufuna ukuvalwa).
Inani lee-analog transmitters ezisetyenziselwa ukubeka iliso kwiparamitha yokhuseleko iya kuxhomekeka kwinqanaba lengqibelelo yenkqubo (ukuhlelwa kokhuseleko) imfuno ye-loop, i-100% yobungqina bomjikelo wovavanyo lwe-loop kunye nenqanaba lokuxilonga elikhoyo kwi-transmitter.
Isignali ye-analog yendawo itsalwa kwiKhadi Lokuphelisa Igalelo le-Analog. Apho amanqanaba engqibelelo yokhuseleko afuna ukuba ngaphezulu kwesinye isidluliseli sisetyenziselwe ukubeka iliso kwiparamitha yokhuseleko, ngoko imiqondiso eyongezelelweyo ye-analog yokufakwayo kufuneka ifakwe iintambo ukwahlula amaKhadi okuphelisa apho kunokwenzeka. I-Simplex circuitry kwikhadi lokuphelisa kufuneka ithathelwe ingqalelo ukuthembeka njengenxalenye ye-loop transmitter (umzekelo, i-fuses kunye ne-resistors esweni apho ifakwe khona). Jonga kuMfanekiso B-1.
Umqondiso uqhagamshelwe kwikhadi lokuphelisa kwimodyuli yegalelo le-Triguard SC300E ngokusebenzisa intambo yenkqubo eqhelekileyo, edibanisa kwisokethi kwi-Hot Repair Adapter Card okanye i-chassis connector.
