RPI_DCV8 is a 8 channels acquisition board for Raspberrypi. Any of AC current & voltage or DC current & voltage can be setup at assembly/purchase time.
- 8 Channels.
- Instrumentation amplifiers.
- Measure RMS or Average signal.
- Fit on Raspberrypi 4 holes mounting pattern.
- Atmega328p Mcu (Arduino UNO)
- MCP3208 ADC (12bits)
- Screw Terminal connectors.
Channel Setup
The idea of the RPI_DCV8 brings a customisable base to setup each channel as per your requirement. We will setup for you the channel type and range at purchase time. Currently supported type of channels are:
- AC Current (using both Voltage and Current CT).
- AC Voltage.
- DC Current.
- Dc Voltage.
- Thermocouple.
DC Current
DC current can be read using a Clamp meter suitable for DC. An example unit is the BT-605A where currents up to 600A can be measured.
The amplification stage can be adapted on the RPI_DCV8 to adjust for desired range.
AC Current
For measuring AC current current a Current Transformer (CT) must be used.
RPI_DCV8 can host the burden resistor for current output CT.
Thermocouple
K Type
K type thermocouple can be used and offer measuring range up to 1350 Celsius.
