Mitsubishi AJ55TB2-16R AC Digital Input Module for MELSEC-F Series

The Mitsubishi AJ55TB2-16R (AJ55TB2-16R) is an AC digital input module developed by Mitsubishi Electric for use with MELSEC-F (FX) series programmable logic controller systems. Designed to facilitate digital signal interfacing in industrial automation setups, this module provides 16 digital AC input points to monitor field devices, sensors, and external operational switches. Functionally equivalent to the FX16EXA1TB unit, it serves as a reliable replacement or expansion option for legacy machinery and existing MELSEC-F controller architectures requiring alternating current input processing. Integrating the AJ55TB2-16R into your automation control panel allows for seamless input handling and system signal coordination. The sixteen-point AC input capacity ensures dependable state detection and communication between field components and the central processor. It is commonly deployed in manufacturing environments, automated assembly lines, packaging machinery, and material handling systems where legacy Mitsubishi Electric MELSEC-F hardware is installed. This module delivers steady input switching performance, making it a critical spare part for maintaining system uptime and extending the operating lifespan of legacy automated installations.
