Mitsubishi AJ65SBTB1-16D Remote I/O Unit Series

AJ65: CC-Link remote I/O unit ряд

SBT: CC-Link remote module

Б1: Compact terminal block type

16Д: 16-point DC digital input module (Цифровой вход)

Позиционирование: CC-Link remote input station, занимающий 1 station address. It is used for remote DI signal acquisition, compatible with Q/A/L series master ПЛКс, and is one of the most widely used remote DI modules for CC-Link fieldbus.

Основные технические характеристики

Рекомендации по подключению проводов

1. Клеммный блок: 16 DI channels + COM-терминал. COM supports both positive and negative common, so NPN and PNP sensors can be wired directly.
2. Bus terminals: И, БД (CC-Link signal lines) + FG shield earth.
3. Источник питания: Module powered by DC24V. Use the same power supply for the module and sensors, and keep common ground.
4. Terminating resistor: Install 110Ω CC-Link terminating resistor at the first and last stations on the bus.
5. Station address setting: Set the CC-Link station number (1~64) via the DIP switch on the side of the module; settings take effect after power cycle.

Сценарии применения

Distributed DI acquisition on production lines: Фотоэлектрические датчики, бесконтактные переключатели, кнопки, limit switches and E-stop signals collected remotely.

Cabinet split wiring: Main PLC installed in central control cabinet; AJ65SBTB1-16D mounted locally on equipment control boxes to eliminate long-distance multi-core cables, only one CC-Link bus cable is needed.

Compatible master stations: вопрос, А, L series PLCs (with CC-Link master modules QJ61BT11N / AJ61BT11, и т. д.)

Программное обеспечение для программирования: GX работает2 / GX работает3. Configure remote I/O stations in CC-Link network parameters; remote input soft elements are assigned automatically.

Поиск неисправностей

1. Индикатор RUN выключен: Check DC24V power supply and polarity.
2. LERR indicator flashing: Duplicate station number, bus breakage, DA/DB перевернуты, отсутствует оконечный резистор, or communication interference.
3. No input signal: Check sensor power supply, COM wiring, input voltage, or damaged optocoupler.
4. Input permanently ON: Shorted sensor or short circuit to ground on field wiring.
