Description
Mitsubishi A6TBX70 Terminal Board 70-Point Sink Input MELSEC A-Series PLC
The Mitsubishi Electric A6TBX70 is a 70-point sink-input terminal board designed for use with Mitsubishi MELSEC A-series programmable logic controller systems. It provides a wiring interface that connects field-side I/O devices — sensors, switches, and other input devices — to the PLC's input modules via a multi-pin ribbon connector, allowing organized, reliable termination of field wiring without direct connection to the PLC module itself.

Applications
Terminal boards like the A6TBX70 are standard wiring accessories within Mitsubishi's MELSEC A-series PLC ecosystem, which was one of Mitsubishi Electric's primary industrial automation platforms from the 1980s through the early 2000s. The MELSEC A-series is a modular, rack-based PLC family widely used in manufacturing, process control, machine tool automation, and material handling applications throughout Japan and internationally. Terminal boards serve as the field-wiring interface layer: rather than terminating dozens of field wires directly onto the PLC input card, technicians wire to the terminal board, which then connects to the card via a single ribbon cable — simplifying wiring, improving serviceability, and protecting the PLC module from direct field-side stress. The A6TBX70's 70-point capacity corresponds to larger-format MELSEC A-series input modules. These boards remain in active use wherever legacy MELSEC A-series systems are still running, and are commonly sought for maintenance, system expansion, and replacement of worn or damaged terminal boards in existing installations.
This Mitsubishi A6TBX70 Terminal Board has been inspected and is in good used condition. The terminal contacts and screw terminals appear clean and intact. The label on the rear is clear and fully legible. The unit shows light surface wear consistent with normal use and storage. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
