Mitsubishi A6TBX70-E Digital Input/Output Module for MELSEC-F FX Series

The Mitsubishi A6TBX70-E (A6TBX70-E) is a combination digital input and output module designed for use with Mitsubishi Electric MELSEC-F (FX) series programmable logic controllers. Serving as an expansion unit for industrial control applications, this discontinued module expands system capacity by delivering a total of 96 digital input and output channels in a single assembly. It is equivalent in function and specification to the FX2C96MTBB unit. The module provides 48 digital inputs operating at a nominal 24 V DC supply voltage alongside 48 digital outputs, also rated for 24 V DC operation. This balanced configuration enables direct interfacing with a wide variety of field devices, including sensors, switches, indicators, and actuators within automated machinery and manufacturing environments. By consolidating 96 mixed I/O points into one unit, the A6TBX70-E supports streamlined wiring and space-efficient cabinet integration in legacy factory automation architectures, assembly lines, and material handling systems that rely on the MELSEC-F series platform.
