Mitsubishi A8GT-EXCNB Analog Output Interface Module for MELSEC-F Series

The Mitsubishi A8GT-EXCNB (A8GT-EXCNB) is an analog output interface module developed for Mitsubishi Electric MELSEC-F (FX) series programmable logic controllers. Designed to deliver precise analog control within industrial automation setups, this module provides two dedicated analog output channels capable of delivering either 0 to 10 V DC voltage signals or 4 to 20 mA current loops. Operating with a 12-bit conversion resolution, the unit ensures accurate signal generation for connected field equipment, serving as an equivalent to the FX2DABB configuration. The module interfaces directly with compatible MELSEC-F controllers to translate digital processor commands into smooth analog regulation signals. Typical applications include controlling speed references on variable frequency drives, modulating proportional control valves, adjusting heating elements, and directing process automation instruments that require continuous analog command values. Its dual-output design allows simultaneous or independent control across two circuits. The Mitsubishi A8GT-EXCNB offers a reliable solution for maintaining, repairing, or expanding existing MELSEC-F automation architecture where stable analog signal transmission is essential.
