Mitsubishi AB6938-C-139 Digital Mixed I/O Module for MELSEC-F FX2N Series

The Mitsubishi AB6938-C-139 is a combined digital input and output module designed for use with Mitsubishi MELSEC-F FX2N series programmable logic controllers. Functioning as an expansion unit equivalent to the FX2N16MT configuration, this module provides discrete signal interfacing for industrial control systems. It features a total of 16 digital input and output points, configured with 8 digital inputs operating at 24 V DC and 8 digital outputs operating at 24 V DC. The digital inputs accept 24 V DC signals from sensors, switches, and pushbuttons, while the 24 V DC digital outputs switch control devices, indicator lamps, and auxiliary machinery circuits. Built for direct integration into FX2N PLC architectures, the AB6938-C-139 ensures reliable signal transmission and consistent switching performance in factory operations. Typical applications include packaging machinery, automated assembly systems, conveyor routing, and general discrete automation tasks requiring combined 24 V DC digital inputs and outputs within a single compact module.
