Product Description

Tavsif

Allen-Bradley 1771-IA PLC-5 va 1771 I/O platforma arxitekturalarida ishlashga mo‘ljallangan eski avlod diskret kirish modulidir. Ushbu standart AC/DC kirish moduli sanoat boshqaruvi ilovalarida ishonchli sezishni ta’minlaydi; unda kontaktlarning titrashi va tarqaluvchi elektr shovqini sababli yuzaga keladigan kuchlanish o‘tkinchi jarayonlari ta’sirini kamaytirish uchun o‘rnatilgan kirish filtri mavjud. Modul tugmalar, chegaraviy kalitlar va AC yaqinlik datchiklari kabi dala qurilmalariga bevosita ulanadi.

Modul ish quvvatini tizim quvvat manbaidan bevosita 1771 I/O shassisining orqa paneli orqali oladi va 75 mA orqa panel toki sarflaydi. Orqa panel ulagichidagi mexanik kodlash halqalari modul elektron platasidagi slotli kesiklar bilan moslashib, modulning mos bo‘lmagan shassi slotlariga noto‘g‘ri kiritilishining oldini oladi hamda ulangan uskunani konfiguratsiya xatolaridan himoya qiladi.

FAQ

What control systems and chassis are compatible with the Allen-Bradley 1771-IA?

The Allen-Bradley 1771-IA discrete input module is specifically designed for operation within the legacy PLC-5 and 1771 I/O platform architectures. It mounts directly into standard Allen-Bradley 1771 I/O chassis and draws 75 mA of operational current directly from the system backplane power supply. Additionally, the unit incorporates mechanical keying bands on the backplane connector to prevent incorrect insertion into unauthorized slots.

What are the nominal voltage ratings and operating limits for the Allen-Bradley 1771-IA?

The Allen-Bradley 1771-IA supports nominal input voltages of 120 VAC (47 to 63 Hz) and 125 VDC for various industrial sensing applications. Its on-state voltage range spans from 87 to 138 VAC or 97 to 138 VDC, while the maximum off-state voltage is rated at 46 VAC peak or 57 VDC. These electrical specifications allow the module to interface reliably with standard field devices like limit switches, pushbuttons, and AC proximity sensors.

How does the Allen-Bradley 1771-IA handle electrical noise and transients?

The Allen-Bradley 1771-IA features built-in input filtering with nominal filtering delays specifically engineered to minimize voltage transients caused by contact bounce and radiated electrical noise. Furthermore, the module provides 1 kVAC rms opto-electrical isolation between the field input devices and the backplane logic circuitry. This robust noise immunity ensures stable and reliable signal monitoring in harsh industrial automation environments.

What safety precautions are necessary when installing the Allen-Bradley 1771-IA?

When installing or removing the Allen-Bradley 1771-IA, technicians must ensure that all power to the 1771 I/O chassis is completely removed to prevent equipment damage or electrical hazard. It is essential to verify that the backplane keying bands correspond exactly to the slots on the rear edge of the module circuit board prior to insertion. Installers should also calculate total backplane current requirements across all installed modules to prevent power supply overload.
