Allen-Bradley 1746-A4 — Allen-Bradley SLC 500 dasturlashtiriladigan mantiqiy kontroller (PLC) tizimi uchun mo‘ljallangan 4 uyali modulli kengaytirish shassisi. Ushbu apparat raki to‘rttagacha I/O yoki aloqa modulini joylashtirish va o‘zaro ulash uchun zarur mexanik korpus hamda elektr orqa panelini ta’minlaydi. Kengaytirish yoki mahalliy mustaqil rak sifatida 1746-A4 kontrollerlarga diskret, analog va maxsus modullarning kengroq taqsimoti bilan ishlash imkonini berib, tizim arxitekturasini kengaytiradi.

Shassi o‘rnatilgan orqa panelga ega bo‘lib, u o‘rnatilgan modullar hamda protsessor yoki adapter o‘rtasida quvvat va aloqa signallarini taqsimlaydi. Unda eng chap uyaga o‘rnatiladigan maxsus quvvat ta’minoti bloki uchun joy mavjud bo‘lib, u orqa panel shinasiga barqarorlashtirilgan kuchlanishlarni yetkazib beradi. Mustahkam ekstrudirovka qilingan alyuminiy orqa panel ramkasida sanoat korpuslari ichida panelga ishonchli o‘rnatish uchun o‘rnatilgan mahkamlash quloqchalari mavjud; bu yuqori tebranishli ishlab chiqarish muhitlarida ishonchli mexanik va elektr yerga ulanishini ta’minlaydi.
