The RPC-1E-UNI is a single-channel universal Relpol product that is designed to monitor a range of electrical parameters such as voltage, current, power, reactive power and energy values. It is capable of both 4-20 mA as well as optional 0-10 V output and can be configured for analogue and pulse signals with optional adjustable time period from 0.5 sec to 24 h. The device can measure up to five currents, three limited and two voltages with a max rating of 32 A for each current. Furthermore, it also has a built-in 8-bit Counter/Board which is useful for counting pulses coming from various sources. The device includes programmable switching events, allowing it to measure RMS and Crest Factors, as well as automatic power factor correction. A web based user interface allows for device configuration and data logging, which can be easily integrated into third party software packages.
