Multimeters

Flexible extension modules for RTU500 series

RTU’s multimeter devices enable direct measurement of voltage, current and power. The configuration of the devices is completely integrated into the easy-to-use RTUtil500 and the DIN rail wizard. Multimeters provide for detailed monitoring of the network. To locate a fault, multimeters offer to fault current detection with directional information.

Additionally, the increased and reliable information about the network protects your investments and allow for precise new investments, if need be.
