Mitsubishi Electric FX3U-64MR/DS Logic Module

The Mitsubishi Electric FX3U-64MR/DS is a 64-point discrete I/O logic module in the FX3U series designed for DIN-rail or panel mounting in control panels and FX3U PLC racks to coordinate sensors and actuators in automated systems. Operated at 24 VDC, it provides 32 inputs and 32 transistor outputs (24 VDC) with sinking/source compatible inputs and 24 VDC transistor outputs. It stores on-board user logic memory and supports FX3U expansion I/O modules for scalable configurations. Optional serial and Ethernet communication modules are supported, and status LEDs indicate power, run, error, and I/O states. With industrial-range operating temperature, it is designed for discrete logic control and I/O coordination across manufacturing lines, including packaging machinery, conveyors, material handling equipment, assembly lines, HVAC systems, and standalone automated machines requiring 24 VDC I/O. Common replacements include Mitsubishi FX3U-48MR/DS, Omron CP1H-X64DR-A, and Allen-Bradley MicroLogix 1400 32/64 I/O series.
