The AJ65SBTB1-32D is a small‑size CC‑Link remote DC input unit designed to be installed close to sensors and switches in the field, reducing wiring between the machine and the PLC while maintaining fast, noise‑immune signal transmission over CC‑Link. It offers 32 digital inputs at 24V DC, with each input supporting both sink and source wiring (positive/negative common shared type) so you can connect NPN or PNP devices flexibly on two common groups of 32 points/common (1‑wire terminal block type).
Inputs are rated at 24V DC with approximately 7mA input current, operating over 19.2–26.4V DC (ripple ≤5%), and feature 1.5ms max ON→OFF and OFF→ON response times at 24V, suitable for general-purpose limit switches, proximity sensors, and pushbuttons. Photocoupler isolation protects the CC‑Link network and PLC from field noise and faults, while the module’s own supply requires only 24V DC (20.4–26.4V) at up to 45mA with all inputs ON, providing an energy‑efficient remote I/O solution.
The unit occupies one CC‑Link remote I/O station (32 input points) and connects via dedicated CC‑Link cable, supporting network speeds up to 10Mbps and distances up to 1.2km (with repeaters, per CC‑Link rules). A compact IP2X housing (50×179×40mm, about 0.25kg) with screw terminal blocks is designed for mounting inside control panels, complying with JIS B 3502 / IEC 61131‑2 for vibration and shock resistance, and operating from 0–55°C in 10–90%RH non‑condensing environments.
