In conjunction with PQ S module: Measurement and recording of power quality according to DIN EN 50160
The UMD 707RCM is a compact high-end fault current measuring device for mounting on the DIN rail. It measures 5-channel fault currents (type A) and voltage quality (harmonics up to 128. Harmonic; voltage dips 40 μsec). The measurement is carried out via the RCM-CT fault current transformers. The device has a large 512 MB memory. The device can be accessed via the Ethernet interface and live measured values can be viewed via the web browser via the associated web server. This means that Internet protocols such as NTP can also be read in. PLC systems and building control systems can be easily controlled
Connect Modbus TCP. Digital inputs/outputs and a serial RS485 interface are integrated. The GO firmware module enables oscilloscope functions for voltage and sets trigger signals for limit value events. There is also a PT100 input.
