I-AI880A High Integrity Analog Input Module yakhelwe ukucushwa okukodwa nokungafuneki.Imojula inamashaneli okokufaka angu-8 amanje.Ukumelana nokokufaka kungu-250 ohm.
Imojula isabalalisa umphakeli wesithumeli sangaphandle esiteshini ngasinye.Lokhu kungeza uxhumano olulula ukuze kusatshalaliswe ukunikezwa kuma-transmitters anezintambo ezingu-2- noma ezi-3.Amandla okudlulisela agadiwe futhi amanje anomkhawulo.Zonke iziteshi eziyisishiyagalombili zihlukanisiwe kuma-ModuleBus eqenjini elilodwa.Amandla kuModule akhiqizwa ku-24 V ku-ModuleBus.
I-AI880A ithobela isincomo se-NAMUR NE43, futhi isekela imikhawulo elungisekayo phezu nangaphansi kobubanzi.
Izici nezinzuzo
- Iziteshi ezingu-8 zika-0...20 mA, 4...20 mA, okokufaka okukodwa okuphelile kwe-unipolar
- Ukucushwa okukodwa noma okungafuneki
- Iqembu elingu-1 lamashaneli angu-8 ahlukanisiwe nomhlabathi
- 12-bit ukulungiswa
- Umsebenzi we-DI we-Loop Ogadiwe
- Umkhawulo we-alamu olungisekayo wokuphuma kwamandla enkambu
- Okulungisekayo phezu/ngaphansi kobubanzi bokufakwayo kwamanje
- Ukunikezwa kwamanje kwama-transmitter anomkhawulo ngesiteshi ngasinye
- Ukuxilongwa okuthuthukisiwe okusebhodini
- Igunyazwe i-SIL3 ngokuya nge-IEC 61508
- Igunyazwe Isigaba 4 ngokuya nge-EN 954-1
- Ihambisana nesincomo se-NAMUR NE43, futhi isekela imikhawulo elungisekayo phezu nangaphansi kobubanzi
- I-HART pass-through communication (AI880A)
Ama-MTU afana nalo mkhiqizo
