Mitsubishi 1S-VD04E-05 Digital Input Expansion Module for MELSEC-F FX Series

The Mitsubishi 1S-VD04E-05 is a digital input expansion unit module engineered for use with Mitsubishi Electric MELSEC-F FX series programmable logic controllers. Designed to provide expanded input capacity for automated machinery and industrial control panels, this expansion block features sixteen digital input channels operating at 24 V DC. Serving as a functional equivalent to the FX16EXV input block, the module allows control systems to interface seamlessly with field devices, switches, sensors, and peripheral automation equipment. As a dedicated digital input expansion module within the MELSEC-F FX family, the 1S-VD04E-05 offers reliable signal integration and channel expansion for compact PLC architectures. The unit connects directly to compatible base units and expansion lines, ensuring stable signal transmission in machine tool automation, packaging equipment, material handling lines, and factory manufacturing systems. By facilitating straightforward integration with twenty-four-volt direct-current instrumentation, this legacy expansion module supports continued maintenance, retrofitting, and operational readiness for established Mitsubishi PLC installations.
