An Industry Standard Made Better
With this 8 Channel 4-20mA ADC you can get the readings you need on the platforms you love. Need your Raspberry Pi to monitor your Sensors? Not a problem. Want easy Cloud Integration? Hook it up to a Photon. Like tried and true platforms? We support Arduino, Windows, and Linux. We want you to monitor your world, your way using simple plug and play.
This 4-20mA ADC combines the power and reliability of the popular industry standard with the adaptability and functionality of all of our I2C products.
Not only can you use and switch between today's most popular platforms using swappable adapters, you can also expand and adapt your device's functionality in a true Plug and Play System. The I2C port on the board allows you to chain multiple devices together. Need to add Relay Control? Just pop one of our I2C Relay Controllers onto the end of your I2C chain and in seconds it'll jump to life at your command.
We have hundreds of chainable I2C devices available. For a full list see our Cross-Platform section.
This I2C 8-channel 4-20mA current receiver board is capable of reading 0-10V input voltage. It includes an onboard amplifier for signal conditioning. This board uses two MCP3428 to read the amplified signal. The MCP3428 is a 4-Channel Analog to Digital Converter with a configurable 12-Bit or 16-Bit resolution, ideally suited for low-speed high-resolution sensor monitoring. The MCP3428 is capable of reading analog voltages at 15 samples per second with 16-Bit resolution or 240 samples per second at 12-bit resolution. The MCP3428 has an x1, x2, x4, x8 programmable gain amplifier, making it an ideal choice for monitoring extremely low-voltage sensors. All 8 channels are capable of monitoring a full-scale range of 4-20mA, 0-40mA, 0-20mA. Up to 8 MCP3428 devices are capable of sharing a single I2C communication port, using three floating address inputs.
This 4-20mA current receiver board has two MCP3428 ADCs onboard, which must be jumper configured to different I2C addresses.
Set MCP3428 gain to one to read 0-40mA signal, set the gain at two to read 0-20mA and 4-20mA signals.
