Mitsubishi SC-J2SBJ4KT02K Servo Amplifier Renewal Kit for MR-J2S-B to MR-J4-B 100/200 W

The Mitsubishi SC-J2SBJ4KT02K is a servo amplifier renewal kit for converting MR-J2S-B servo amplifier installations to MR-J4-B units in 100/200 W applications. Mitsubishi Electric lists it in the FA-Servo-Motion other option group as a renewal kit with material number 271221. It supports MELSERVO replacement projects and is specified for 200 V HC-MFS series servo motors, including standard and brake-equipped versions used in small-capacity, ultra-low-inertia axes. The kit measures approximately 62 mm wide, 204 mm high and 135 mm deep, with a weight of about 0.9 kg, and it is RoHS compliant. Mitsubishi's replacement documentation describes first-stage servo amplifier replacement, later servo motor replacement and combined replacement procedures. In a typical 100/200 W axis, the kit provides the connection interface between the existing MR-J2S-B installation and the replacement MR-J4-B servo amplifier, allowing the drive to be renewed as part of a planned MELSERVO upgrade.
