SDAFE-HART Software Defined Analog Input Module with HART Compatible Modem

Regular price $59.95 Sale

SDAFE™ "Software Defined Analog Front End"

Each SDAFE™ Analog Module can be programmed thru the application software to be 4-20 mA, 1 to 15 VDC or 0 to 10 VDC input. All modules are factory calibrated with 6 break point calibration per input type.

Typical resolutions are +/- .005 mA for 0 thru 20 mA. +/- .005 VDC for 0 to 5 VDC and 0 to 10 VDC Inputs.

The SDAFE™ communicates via SPI, and is powered from a single +3.3VDC or +5VDC source. The A/D converter is a 15 bit A/D.

The HART compatible modem allows the attached HART enabled transmitter to communicate with the RPi via the GPIO Uart.

The SDAFE-HART is compatible with the:

PI-SPI-DIN-2x4MIO Interface and the PI-SPI-DIN-RTC-RS485-4AI-4KO-8DI Interface
