What it is and what it does
The Mitsubishi AJ65SBTB32-16DR is an 8-point digital input expansion module for the AnS series PLC platform. It accepts both sink and source input configurations, making it compatible with a wide range of field devices (PNP or NPN sensors, limit switches, pushbuttons) without reconfiguration. The module adds eight isolated input channels to an existing base setup, typically used when the local I/O on the CPU or a remote rack needs to grow.
