Yaskawa DF9200733-B0 (JANCD-MFC03-2) Absolute Encoder Board
The DF9200733-B0, marked JANCD-MFC03-2 Rev B0, is a dedicated absolute encoder interface board designed for Yaskawa Motoman MRC and XRC robot controllers. It adopts natural convection cooling inside the control cabinet, processing encoder signals from all servo axes and retaining position data via backup battery after power-off. Featuring stable circuit design and reliable signal transmission, it is ideal for high-precision robot systems that require position memory and no repeated homing.
