Product Description

Tavsif

Allen-Bradley 1771-ALX — 1771 I/O arxitekturasi tarkibidagi mahalliy I/O shassilarini ulash uchun ishlab chiqilgan PLC-5 mahalliy I/O adapter modulidir. I/O shassisining eng chap slotiga o‘rnatish uchun mo‘ljallangan ushbu modul mahalliy I/O shinasi orqali aloqani boshqaradi hamda butun tizimni o‘chirishni talab qilmasdan alohida stoykalarni uzish imkonini beradi. Issiq uzish imkoniyati texnik xizmat ko‘rsatish vaqtida interconnect kabellarini olib tashlashga, shu bilan birga tizimdagi quyi oqim shassilariga shina aloqasini uzmaslikka imkon beradi.

Modulda muayyan qo‘llanma uchun backplane sozlamalariga moslashtirilishi kerak bo‘lgan ichki konfiguratsiya kalitlari mavjud. U 1771-CX1, 1771-CX2 va 1771-CX5 kabi standart interconnect kabel variantlarini qo‘llab-quvvatlaydi hamda shina zanjiridagi oxirgi adapterga 1771-CXT terminator vilkasini talab qiladi. Standart sanoat avtomatizatsiyasi muhitlarida ishonchli ishlaydigan 1771-ALX eski PLC-5 boshqaruv tizimlari uchun backplane’ni mustahkam boshqarish imkonini beradi.

Ulanishlar / Interfeyslar

1771-ALX modulida qo‘shni 1771 I/O shassilarini ulash uchun interconnect kabellariga mo‘ljallangan fizik portlar mavjud. Old paneldagi ulanishlar standart 1771 seriyali ko‘p o‘tkazgichli aloqa kabellaridan foydalanadi. Moduldagi kalit bloklari shassi stoykasi manzillashi va aloqa parametrlariga aniq moslab sozlanishi kerak.

O‘rnatish bo‘yicha ko‘rsatmalar

1771-ALX modulini o‘rnatish yoki chiqarishdan oldin shassiga berilayotgan barcha tizim quvvati o‘chirilganiga ishonch hosil qiling; bundan izolyatsiyalangan kabellarda ruxsat etilgan issiq uzish protseduralari mustasno.
Adapterni faqat belgilangan 1771 I/O shassisining eng chap slotiga o‘rnating.
Modul ulagichlaridagi fizik kalitlash backplane sloti kalitlashiga mos kelishini tekshiring; bu modulni noto‘g‘ri o‘rnatishning oldini oladi.
Ichki konfiguratsiya kalitlarini muayyan PLC-5 tizimi arxitekturasi va stoykalarni manzillash sxemasiga mos ravishda sozlang.
Shinadagi oxirgi adapter 1771-CXT terminator vilkasi yordamida to‘g‘ri terminatsiya qilinganiga ishonch hosil qiling.

FAQ

What is the primary function of the Allen-Bradley 1771-ALX PLC-5 Local I/O Adapter Module?

The Allen-Bradley 1771-ALX is engineered to interface local I/O chassis within a 1771 I/O architecture. Designed for installation in the leftmost slot of an I/O chassis, this module manages communication across the local I/O bus. It allows individual racks to be disconnected without requiring a complete system shutdown, ensuring high availability during maintenance.

How does the hot-disconnect feature of the Allen-Bradley 1771-ALX operate?

The Allen-Bradley 1771-ALX features a hot-disconnect capability that ensures interconnect cables can be removed for maintenance without disrupting bus communication to downstream chassis in the system. This allows technicians to service specific parts of the industrial automation network independently. Proper safety guidelines and system power states must still be observed during physical maintenance procedures.

What cabling and termination accessories are required for the Allen-Bradley 1771-ALX?

The Allen-Bradley 1771-ALX supports standard interconnect cabling options such as the 1771-CX1, 1771-CX2, and 1771-CX5 cables to link adjacent chassis. Additionally, it requires the 1771-CXT terminator plug installed on the final adapter of the bus chain. These components ensure signal integrity across a cumulative bus length of up to 98.4 cable-feet.

What are the power requirements and specifications for the Allen-Bradley 1771-ALX?

The Allen-Bradley 1771-ALX draws a backplane current of 1.2A at 5VDC during standard operation. It exhibits a power dissipation ranging from 5.7 to 6.3 watts, resulting in a thermal dissipation of 19.44 to 21.48 BTU/hr. These electrical parameters must be factored into the overall power budget of the 1771 I/O chassis.

How is the Allen-Bradley 1771-ALX configured during installation?

The Allen-Bradley 1771-ALX features onboard configuration switches that must be matched with backplane settings for the specific application. Installers must place the module strictly in the leftmost slot of the designated 1771 I/O chassis. Verifying physical keying and correct switch addresses ensures proper communication within legacy PLC-5 control systems.
