Mitsubishi 20-VPR-25D Digital Output Expansion Module for MELSEC-F FX Series

The Mitsubishi 20-VPR-25D (20-VPR-25D) is a digital output expansion block designed for use with Mitsubishi Electric MELSEC-F (FX) series programmable logic controllers. Engineered to expand the input and output capacity of FX series automation systems, this unit provides sixteen digital outputs configured with normally open relay contacts. It serves as a direct functional equivalent to the FX16EYRESULBB module, offering seamless integration and signal switching for legacy industrial control setups. This expansion unit enables programmable controllers to actuate external field devices such as solenoid valves, motor starters, indicators, and auxiliary contactors in automated machinery and production lines. Now discontinued by the manufacturer, the module remains critical for maintaining, repairing, and retrofitting existing MELSEC-F PLC architectures without requiring extensive system reprogramming or panel redesign. It delivers dependable contact isolation and switching performance across diverse factory automation applications.
