Product details

The Mitsubishi AJ65SBTB1-32DT is a CC-Link remote I/O station delivering 16 DC inputs (sink type, 24 VDC, 7 mA typical) and 16 transistor outputs (sink type, 24 VDC, 0.5 A per point, 3.6 A per common bus). Input isolation is photocoupler; output side adds overload, overvoltage, and overheat protection — a step up from basic fuse-only modules. Power draw: 60 mA at 24 VDC with all points ON, so the station adds roughly 1.5 W to the 24V rail.

The NZ2EX2B1-16D is a 16-point DC input module for the MELSEC iQ‑F series — same function class but no outputs, no CC‑Link interface, and a different physical footprint (slim 12mm slice vs 179mm wide standalone block). It is not a drop‑in second‑source. For a pure input expansion on an iQ‑F base it is the modern equivalent, but the AJ65SBTB1-32DT remains the correct fit for CC‑Link networks needing combined I/O in a single addressed station.

Panel‑mount only: 179 mm wide × 40 mm deep, rated IP2X. Pollution degree 2, overvoltage category II. Input supply tolerates 19.2–26.4 VDC (ripple ≤5%), so it rides through weak 24 V bus conditions. Output common is 32 points per common on a trapezoid terminal block — plan wire routing to keep the 3.6 A common limit. Surge suppression via zener diode on outputs. No corrosive gas environment specified; storage at 10–90% RH non‑condensing.

Frequently asked questions

Can the NZ2EX2B1-16D replace the AJ65SBTB1-32DT?

No. The NZ2EX2B1-16D is a 16‑point input module for the MELSEC iQ‑F series — it has no outputs and no CC‑Link remote station interface. It is not electrically or mechanically interchangeable.

What is the mass of the AJ65SBTB1-32DT?

The unit mass is 0.25 kg. Shipping weight is 1.3 kg due to packaging.

What is the current consumption?

60 mA or less at 24 VDC with all points ON, plus a typical 7 mA per input channel.
