SUZLON - P/N: 51025002 is Woodward’s P/N 8441-1120 was a customized multifunctional relay  called MFR1371M/DQRSU08UV mainly used on 2MW+ wind mills.  This MFR13 is connected via CAN bus to the upper level PLC.


This device has a special customized CAN protocol with option Su08.
P/N  8444-1115 MFR300-71M/SU08 comes with a compatible CAN protocol.


So MFR13 can get replaced by  this MFR300, thus you can make sure to maintain the upper PLC.


You can use the same configuration cable P/N 5417-557 DPC-1 or the latest P/N 5417-1251 DPC-USB can be used.
