The AJ65SBTB1-16D is a compact CC‑Link remote input unit designed to bring 16 field digital signals (from sensors, switches, and contacts) into a MELSEC PLC system via the CC‑Link network, reducing home‑run wiring and simplifying modular machine layouts. Each of the 16 inputs is rated for 24V DC (19.2–26.4V operating range) with about 7mA input current and supports both sink and source wiring thanks to its positive/negative common shared (sink/source shared) configuration, grouped as 16 points per common using a 1‑wire terminal block.
The module offers fast response times of 1.5ms or less for both OFF→ON and ON→OFF at 24V, making it suitable for general limit switches, proximity sensors, and operator pushbuttons in typical PLC scanning applications. Photocoupler isolation between field inputs and internal circuitry improves noise immunity and protects the CC‑Link network and master station. The unit itself is powered by 24V DC (20.4–26.4V, ≤35mA with all points ON), ensuring low power consumption in large distributed systems.
As a CC‑Link remote I/O station, it occupies one station (32 input points assigned, 16 actually used) and supports CC‑Link Ver.1.10 at speeds up to 10Mbps with network distances up to 1.2km according to CC‑Link specifications. The rugged, compact housing (about 50×118×40mm, 0.18kg) with screw terminal blocks meets JIS B 3502 / IEC 61131‑2 vibration and shock requirements and operates reliably from 0–55°C and 10–90%RH non‑condensing, making it suitable for control panels in a wide range of industrial environments.
