Mitsubishi BL296SB-16F-V50 Digital I/O Board for MELSEC FX Series

The Mitsubishi BL296SB-16F-V50 (BL296SB-16F-V50) is a combined digital input and output module board manufactured for Mitsubishi Electric MELSEC-F (FX) series programmable logic controllers. Designed as a functional equivalent to the FX48ETESS configuration, this board provides 48 discrete input and output channels to interface control systems with external plant floor instrumentation. The technical architecture includes 24 digital inputs rated for 24 V DC operation and 24 digital outputs rated for 24 V DC with positive logic (source) switching behavior. It serves to acquire process feedback from sensors and limit switches while simultaneously driving discrete control devices such as solenoids, indicators, and relays. Now out of production, this module is an essential replacement spare part for maintaining, repairing, and sustaining operational continuity in legacy Mitsubishi automation installations. It helps facility managers prevent costly system retrofits by keeping existing machinery running without control software modifications. Typical industrial applications include automated assembly equipment, packaging machinery, conveyor lines, and material handling systems utilizing MELSEC-F control architectures.
