MCP3428 4-Channel 0-20V Analog to Digital Converter with IoT Interface

This Analog to Digital Converter Board is capable of reading 0-20V input voltage. It has an on-board Amplifier for signal conditioning. This Board uses MCP3428 to read the amplified Signal. The MCP3428 is a 4-Channel Analog to Digital Converter with 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 4 channels are capable of monitoring a full-scale range of 0-20V. Up to 8 MCP3428 devices are capable of sharing a single I2C communication port, using floating address inputs.

This 0 to 20V Analog to digital Converter board has a MCP3428 onboard, so to use more than one MCP3428 at the same time you will need to set them up to have different addresses. This Analog to Digital Converter board has onboard jumpers to select the different addresses for the MCP3428.

Note: Set MCP3428 gain at one to read 0-20V Signal and set the gain at two to read 0-5V Signal.

What is the NCD IoT Interface?

The NCD IoT Interface provides users with a means of changing or upgrading the IoT communications technology as new technologies emerge.  The NCD IoT Interface is directly compatible with Particle Photon for WiFi communications, Electron for Cellular Communications, Bluz for Bluetooth.  Optionally, adapters may be installed to provide a direct interface to Arduino Nano, Micro, USB, PyCom WyPy, Onion Omega, Raspberry Pi, and much more.  The NCD IoT interface allows you to re-use your hardware so it never becomes obsolete!  Based on I2C communications, the NCD IoT Interface uses only 2 GPIO lines of your microcontroller, freeing the rest of your CPU for other tasks.

Unlimited I2C Expansion

Based on our plug-and-play I2C interface standard, all NCD IoT devices are equipped with a I2C expansion port, making it easy to expand to a wide variety of sensors, current monitors, relay controllers, PWM controllers, and much more!  We are always designing new expansions for our plug-and-play I2C framework.  We are dedicated to building a product line of interconnected devices to simplify all forms of automation.  Re-use or upgrade your hardware in seconds by selecting the modules that best fit your needs, and chaining them together using the included I2C expansion cables!
