Product Description

The Mitsubishi AJ65SBTB2-16T is a remote digital output module designed for use with MELSEC-A Series programmable logic controllers (PLCs). This module features 16 transistor-type outputs configured for sinking (NPN) logic, making it suitable for controlling various industrial devices such as solenoids, relays, and indicator lights. It operates with a 24V DC power supply and communicates via the CC-Link network, allowing for efficient integration into distributed control systems.​
