Web Sensor - two channel remote 0-20mA inputs to ethernet
Converter Web Sensor P2520 is designed for the connection of two sensors with current output into the Ethernet network. The measured
current (0-20mA or 4-20mA) can be converted to the physical quantity that is measured by the connected sensor. The converter is galvanically isolated from the Ethernet communication lines, current inputs and power supply are not galvanically isolated.
