Mitsubishi 1F-VD01E-02 Digital I/O Module for MELSEC-F FX Series

The Mitsubishi 1F-VD01E-02 (1F-VD01E-02) is a combined digital input and output unit module engineered for Mitsubishi Electric MELSEC-F (FX) series programmable logic controllers. Designed to expand the control capabilities of automated machinery, this out-of-production module provides a total of 128 input and output channels in a single footprint. It integrates 64 digital inputs operating at 24 V DC alongside 64 digital outputs operating at 24 V DC with positive source logic, functionally serving as an equivalent replacement for the FX128MTESSUL unit. This mixed digital I/O module enables high-density signal interfacing between MELSEC-F series controllers and field devices such as sensors, switches, actuators, indicators, and relays. Operating on standard 24 V DC control circuits, the module delivers dependable discrete signal processing and switching performance across diverse factory automation, machine control, and production line environments. By combining extensive digital input and digital output capabilities, the 1F-VD01E-02 helps maintain and support existing MELSEC-F installations requiring reliable discrete I/O expansion.
