PMC-550D
Product Overview
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.
