PI-SPI-DIN-2x4MIO I/O Module

Regular price $124.95 USD Sale

The PI-SPI-DIN-2x4MIO Input/Output I/O Module Interface for the Raspberry Pi is a complete automation solution. This multi I/O Module combines 2 (or more) analog inputs, 2 analog outputs, 2 digital inputs and 2 relay outputs into one seamless module for the Raspberry Pi.

The analog inputs can vary from isolated, non-isolated and HART enabled SDAFE (Software Defined Analog Front End) modules as well as the PI-SPI-DIN series analog input input modules.

The analog input modules (SDAFE and PI-SPI-DIN series) are now sold separately to increase the flexibility of this interface.

Raspberry Pi and SDAFE modules are NOT included.

 Node-Red support is now available.

Please Allow up to 4 weeks for order Processing.

 PI-SPI-DIN-2x4MIO

For applications requiring more isolated analog inputs, the PI-SPI-DIN-2x4MIO can be expanded using the new PI-SPI-DIN-SDAFE-E I/O module. This supports up to 4 SDAFE I/O modules. Each I/O module has 5 chip selects and 4 addresses. With full expansion, the PI-SPI-DIN2x4MIO can have 22 isolated analog input circuits.

Software Defined Analog Front End

Each SDAFE™ Isolated Analog Input I/O Module can be programmed thru the application software to be mA or VDC input. All modules are factory calibrated with 6 break point calibration per input type.

The SDAFE-X55 is an isolated analog signal conditioner. Inputs can be software selected to be either mA or VDC in various ranges and unit types. Signal and power isolation based on the Analog Devices, Inc., iCoupler® technology,

The Isolator Integrated Circuit carries the following Safety and Regulatory Approvals:

  • UL recognition
  • 2500 V rms for 1 minute per UL 1577
  • CSA Component Acceptance Notice #5A
  • VDE certificate of conformity (pending)
  • IEC 60747-5-2 (VDE 0884, Part 2)
  • VIORM= 560 V peak

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.

Standard Ranges:

  • 0 - 20 mA
  • 0 - 5 VDC
  • 0 - 10 VDC

There are three SDAFE I/O modules available and are sold separately,
