P/N LR20025 was a customized multifunctional relay called MFR1375M/PMRSU03UV
mainly used on 1.5MW wind mills. This MFR13 was connected via CAN bus to upper PLC.
There was a special customized CAN protocol with option Su03.
P/N 8444-1093 MFR300-75M/SU03 has same, compatible CAN protocol. So MFR13 can be replaced by this MFR300 without making changes in upper
PLC. Same configuration cable 5417-557 DPC-1 or 5417-1251 DPC-USB can be used
Mains differences :
MFR13 | MFR300 |
| Dimensions: 96 x 72 x 130 mm | 146x128x50 mm |
| 690 VAC voltage sensing | 690 VAC voltage sensing |
| ../5A current sensing | ../5A current sensing |
| Accuracy Class 1 | Class 0.5 |
| MFR13M was with 8923-1023 Din rail brackets back panel mounted | back panel mounted |
| LeoPC configuration software | Toolkit software |
| 2 line numeric dislpay | no display |
| 1 x Discrete Input | no Discrete Input |
| 8 x Discrete Output | 5 x Discrete Output |
| only U,f , P monitoring | additional LVRT monitoring |
| CAN bus | Can bus |
