The Mitsubishi AJ65DBTB1-32T1 is a 32-point transistor output module rated for 0.5 A per point, 8.0 A total per module, commonly used to switch DC loads in AnS/QnA series PLC racks. Outputs are typically sink-type (transistor sourcing current to ground), driving solenoids, indicator lamps, or contactor coils within the rated current per point.
The AJ65DBTB1-32T1 has no direct official replacement listed; for a new build, consider Mitsubishi's current-series output modules for the iQ-F or iQ-R platform if backward compatibility is not required.
