Uruzitiro rw'umutekano ruri ukwarwo ku ruhande rwo gutahura: PHD-11TD-21, uburyo bwo kwinjiza no gusohora analogi, uburyo bwo kwinjiza n'uburyo bwo gusohora inshuro imwe.

^ Uruzitiro rwihariye rushobora gukuraho no kohereza ikimenyetso cya 4 ~ 20mA cyangwa ikimenyetso cya DC 4 ~ 20 mA cyakozwe n'umuyoboro uri mu gace kateje akaga mu gace gateje akaga. Iyo umuyoboro uri mu buryo bw'insinga ebyiri cyangwa eshatu, uruzitiro rw'umutekano rutanga ingufu kuri umuyoboro.

^ Iki gicuruzwa gikeneye amashanyarazi ya 20-35VDC yo hanze.

^ Iki gicuruzwa gishyigikira ikimenyetso cya HART n'intabaza yo guhagarika.

* Icyitonderwa: Niba ukeneye izindi parametre z'iki gicuruzwa, nyamuneka hamagara ubufasha bwacu bwa tekiniki. Niba umusaruro ari izindi parametre, ugaragazwa n'umubare wa 9, kandi parametre zihariye zigaragazwa nyuma y'umubare w'icyitegererezo.

Uruzitiro rw'umutekano rwonyine rw'ibikoresho bya analog rutanga imbaraga zonyinegutanga ibikoresho bibiri na bitatu byo kohereza insinga mu turere twateje akaga.

Ikimenyetso cya 4 ~ 20mA cyakozwe n'icyuma gitanga amakuru cyangwa isoko y'amashanyarazi cyoherezwa giturutse ahantu hateje akaga kijya ahantu hatekanye, bityo bigatuma umutwaro usohoka mu gace gatekanye. Ku byuma bibiri cyangwa bitatu bitanga amakuru ku nsinga cyangwa ibimenyetso by'amashanyarazi, iki kimenyetso cy'umutekano gishyigikira itumanaho ry'ikimenyetso cya digitale cya Hart kiri ku kimenyetso cya 4 ~ 20mA kandi gifite akazi ko kumenyesha ko insinga zacitse.

Iki gicuruzwa gikenera umuriro wigenga, hamwe n'ibikoresho byihariye byo gutanga umuriro, ibyuma byinjira n'ibisohoka.

Umuvuduko w'amashanyarazi	20~35VDC Ikoreshwa ry'ingufu: Iyo 24V itanga umuriro, 20mA isohoka ≤65mA (PHD-11TD-21)
