Mitsubishi BL227XB-FK04VN-P Compact PLC CPU Unit for MELSEC FX3UC Series

The Mitsubishi BL227XB-FK04VN-P (BL227XB-FK04VN-P) is a high-end compact programmable logic controller CPU unit designed for Mitsubishi Electric MELSEC-F FX3UC series automation platforms. Functionally equivalent to the FX3UC-32MT-LT main unit, this central processing unit incorporates 32 onboard digital I/O points, configured as 16 digital inputs at 24 VDC and 16 negative logic sink transistor outputs rated for 5 to 30 VDC. The controller provides high-speed execution with an internal RAM program capacity of 64,000 steps and can support up to 256 directly connected and networked I/O points using expansion hardware. Compact MIL ribbon cable connectors handle the integrated I/O connections to minimize enclosure space requirements. The CPU is equipped with an integrated RS-422 serial interface to facilitate connection with operator panels, programming tools, and external devices. Powered by an external 24 VDC power supply, the unit mounts directly onto a standard DIN rail for rapid assembly into control cabinets. The BL227XB-FK04VN-P is engineered for demanding automation tasks including packaging machinery, assembly cells, material handling systems, and distributed industrial control architectures.
