This I2C 4-20mA Current Receiver Board is capable of reading 4-20mA, 0-40mA, or 0-20mA input Signal from 12 remote sensors. It has an onboard amplifier for signal conditioning. This Board uses three 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 12 channels have differential inputs, capable of monitoring a full-scale range of 4-20mA, 0-40mA, 0-20mA. Up to 3 MCP3428 devices are capable of sharing a single I2C communication port, using three floating address inputs. This board can be used to read 4-20mA output flow sensor, 4-20mA temperature output, 4-20mA float sensor and many more industrial sensors that support the 4-20ma standard.
If you want to interface industrial 4-20mA sensors with Raspberry Pi, Arduino, Particle Photon and all other major platforms, you can use this board with the respective adapter.
Note: Set MCP3428 gain to one to read 0-40mA Signal, set the gain at two to read 0-20mA and 4-20mA signals.
