The USB Isolated Voltmeter Board (USBisoVM) has 6 digital isolated voltmeters that transfer data back to a control module via USB. The USBisoVM Board is a monitoring device only, and requires either a PC or SRMS unit to communicate. Kit contains USBisoVM unit with USB cable, screwdriver and software on CDROM. Just install the software, connect the I/O port connectors, plug in the USB cable and you're ready to read voltages, set up alarms, etc.
Each voltmeter is capable of measuring up to ±100 VDC with 24-bit accuracy. The data and power lines for each voltmeter are isolated with a chip-scale air core transformer. This enables each voltmeter to measure different voltage sources without any effect on the main board or other voltages.
This technology enables the ability to measure (but not limited to): Individual batteries in a battery bank, shunt voltages for equipment that may be drawing or generating power and numerous other applications.
USBisoVM is a unique data acquisition device that uses a standard USB port. Plug it into your SRMS unit or into a Computer.
USBisoVM has six +/- 100 VDC electrically isolated voltmeters.
USBisoVM uses six 24 bit Delta Sigma ADC,s to deliver accurate DC voltage readings.
