Mitsubishi AJ65SBTB1-16DT CC-Link Remote I/O Module 8 Inputs 8 Outputs Sink Type

Mitsubishi Electric AJ65SBTB1-16DT is a terminal block type remote I/O module for CC-Link fieldbus networks. It is a combined module with 8 digital inputs and 8 sink‑type transistor outputs, designed for MELSEC‑A series distributed control systems. The module provides 16 I/O points in a compact 130 mm width enclosure, reducing field wiring and simplifying cabinet installation. Finger protection on the terminal block allows direct mounting on machinery without additional covers. CE, UL, cUL certified.
