It supports single-phase and three-phase measurement configurations, providing detailed information on current, voltage, power, frequency and harmonic distortion. Dual RS-485 communication interfaces with Modbus RTU enable integration into industrial monitoring systems. Combined with OMRON's Condition Monitoring Configuration Tool, it helps maintenance teams analyse equipment conditions, identify developing problems and plan maintenance activities more effectively.
