PI-SPI-DIN-8AI Raspberry Pi DIN Rail Analog Input Interface

  • $32.95


This is the DIN rail mountable version of the Pi-Spi-8AI Analog Input Interface! The PI-SPI-DIN-8AI is based on the popular VP-EC-8AI 8 channel 4-20 mA input module, and the Microchip MCP3208 12 bit A/D converter.

Each module in the PI-SPI-DIN series has two 16 Pin GPIO ports that carry power, SPI, I2C and 5 Chip Selects from the main PI-SPI-DIN-RTC-RS485 Module. Also, each module has it's own 5VDC switching power supply and 3.3VDC LDO regulator.

Each channel can be configured as either mA or Voltage. Another feature is all inputs can easily be configured for thermistor input making the Pi-SPi-8AI an 8 channel temperature sensor module. Please contact us for custom configurations.

Specifications:

  • Two 16 Pin GPIO Ports (Power, SPI, I2C and 5 Chip Selects)
  • 5 VDC 0.5A Switching Power Supply (9 to 24 VDC Input)
  • 3.3VDC LDO regulator
  • Terminal Blocks are rising clamp cage screw type (no leaf springs)
  • Blue LED indicators for power
  • MCP3208 A/D Converter with 12 bit resolution
  • Each analog signal buffered (1/4 LM324 Op Amp)
  • Inputs 1 thru 8 are configured for 4 to 20 mA Input (Standard -20MA Option)
  • All inputs can be configured for either mA, VDC, or Thermistor Input for temperature measurement
  • PCB Dimensions: 2.7" Wide x 3.42" Long
