Relay outputs (rated for resistive loads up to 2 A per point typical for this class) handle inductive loads like contactors and small solenoids without external snubbers, but the mechanical life limits high-frequency switching — budget for solid-state output modules if your application cycles faster than once per second. ## Panel fit and power budget The 285x90x86 mm footprint fits a standard 90 mm wide DIN-rail enclosure — the depth leaves clearance for the backplane wiring ducts and the front-access terminal blocks. Power consumption is listed at 100 W total, with a separate 50 W figure likely covering the CPU and I/O bus — size your 24 VDC supply to handle the full 100 W draw plus any field devices powered from the same rail. ## Sourcing and lifecycle reality Lifecycle status is marked mature — the FX3U series is a well-established Mitsubishi platform still widely specified in existing installations, though not actively promoted for new greenfield designs.","metaTitle":"Mitsubishi FX3U-80MR-ES/A PLC, 80 I/O, Relay Output","metaDescription":"Mitsubishi FX3U-80MR-ES/A programmable controller with 40 inputs, 40 relay outputs, 100W power consumption.
