TCP/IP Voltmeter - version V11

TCP/IP voltmeter V11 enables to measure 2x DC voltage and 2x DC current through the Internet. It includes a two DC voltmeters and two DC ammeters. Voltmeter and ammeter are galvanically isolated from the board. It has low power consumption and it is a perfect equipment for automation and remote measurement.

TCP/IP Voltmeter V11 hardware

TCP/IP voltmeter includes 2 independent A/D converters, which are connected through a galvanic isolator with a microprocessor. Each A/D converter has two inputs. First input is connected as a voltmeter, second as ammeter.
      Voltmeter contains voltage divider on the input, ammeter has a shunt resistor of 0.01 Ohm. Because voltmeters are galvanically isolated from each other, you can measure two different voltages which share common ground or are completely isolated from each other. The same applies for ampermeter. This design also has some limits when you measure current and voltage simultaneously. Read more.
