It sits in the MR-J4 series, Mitsubishi's current-generation servo platform for general-purpose motion control. The '200B4' in the order code points to a 200 V class, B-type frame, 4-axis-capable amplifier variant. For a current-production Mitsubishi servo amplifier, lead times are typically tied to factory build cycles; a firm RFQ with quantity and delivery target gets you the real schedule. ## What This Rating Means for Fit The MR-J4-200B4-RJ020 is a servo amplifier, not a standalone motion controller. It requires a command source — typically a Mitsubishi PLC with a motion module (like the MELSEC iQ-F series) or a dedicated motion controller sending a pulse train or SSCNET III/H fiber-optic command. The amplifier converts that command into PWM power for the servo motor and closes the position/speed/torque loop internally. Because it's a 200 V class amplifier, it needs a 200 V AC three-phase supply (or single-phase, depending on the specific model variant). Verify the input voltage range on the nameplate before wiring — driving a 200 V class unit from 400 V without a transformer will damage the DC bus.","metaTitle":"Mitsubishi MR-J4-200B4-RJ020 Servo Amplifier, Current Produc","metaDescription":"Mitsubishi MR-J4-200B4-RJ020 servo amplifier, current production.
