| Artikelbeschreibung | LV motor protection relay / the PMC-550D motor protection relay seamlessly integrates motor protection, control, temperature monitoring, and insulation monitoring with a modular design. Featuring extensive I/O options, including 10XDI, 5XDO, 2XRS-485 ports, 1X analog output, and 1X residual current input, the relay offers flexibility and expandability, its modular design allows easy expansion, connecting a standalone HMI module for monitoring and control, a PMC-KT module for additional 6XNTC, 2XDI, and 1XDO for temperature monitoring and I/O control, and a PMC-KR module for ground fault insulation monitoring. The relay supports MODBUS rtu/PROFIBUS, with PROFIBUS-DP available as an option. Equipped with a robust power supply, it ensures uninterrupted operation for 30 seconds during power interruptions. These versatile features make the relay suitable for diverse industrial needs |
