The Mitsubishi AJ65SBTC4-16DT is a PLC expansion module from the AJ65SBTC4 series, designed to add discrete I/O capacity to a Mitsubishi PLC system. It sits in the PLC I/O & Expansion Modules category, meaning it connects to a base unit or remote station to extend the number of field-device terminations. The module is classified as mature in its lifecycle stage, indicating it is a stable, long-available product no longer in its initial introduction phase. This is typical for established Mitsubishi I/O modules that have been in the field for years.
For BOM continuity, confirm the I/O count and bus compatibility with the target Mitsubishi base unit — the module mates with the CC-Link or MELSECNET/H remote station depending on the system architecture.
