The IP voltmeter is a universal device that can measure 3 voltages
and transfer data over the internet. The inputs are fully independent and galvanically isolated.
The board is of the plag and play type - after connection to a power source and ethernet it is immediately ready for use.
The board also includes advanced functions
for sending alerts and storing measured data in the cloud.

Reading measured data
The IP voltmeter offers various methods to retrieve the measured data, including accessing it through a web browser, utilizing a TCP client, using an SNMP client, or reading the status.xml XML file.
Start working with IP voltmeter.
- 1. Connect ethernet cable to TCP/IP voltmeter.
- 2. Connect cables for voltmeter and ammeter to measuring device.
- 3. Connect the power supply.
- 4. Start web browser or other application.
When TCP/IP voltmeter is connected to the network and power is on, voltmeter will begin to send and receive packets. This is indicated by yellow and green LED diode.
Read MoreNetwork configuration and setup
The IP voltmeter supports the following protocols: TCP/IP, UDP, HTTP. HTTPS is not supported. The IP voltmeter gets a dynamic IP address when connected to the network.
The IP address is obtained from the DHCP server. The board can also have a static IP address.

The board contains a 3.3V power supply that powers the entire board. Then the processor, Ethernet controller, optocoupler and 2 A/D converters.
The A/D converters are galvanically isolated from the board and the individual channels are also isolated from each other. This solution allows to use the board in various applications without grounding problems.
Read MorePower supply
IP voltmeter is designed for a wide range power supply. IP voltmeter is supplied by external source of +5 to +28 Volts DC. Current consumption is around 77 mA/12V. At higher supply voltages the current is smaller.
The board can be powered from an universal AC/DC power supply adapter or from batteries. The board can also be powered by a battery that is directly measured. Read More
Voltage measurement
When connecting IP voltmeter to other devices, it's important to consider whether to use a common ground or a separate ground. A common ground means that all devices in the system share the same ground reference.

The IP voltmeter offers various methods to retrieve the measured data, including accessing it through a web browser, utilizing a TCP client, using an SNMP client, or reading the status.xml XML file.
Sending alert
The device allows you to send an alert if the value of any voltage reaches a certain set value.
Read MoreSNMP client
Data can also be read via SNMP protocol. The device contains an SNMP agent v2.
