Overview

The DIGIplate is an eight channel digital input board with surge protection on each input. It includes channel to channel isolation as well as input to the Raspberry Pi isolation to prevent noise producing ground loops. Each input can be individually configured to support IEC 61131-2 Type 2 and Type 3 current sinking or a standard digital logic profile. All inputs are 30 volt tolerant and can be driven with both PNP and NPN output devices.

Features

  • Eight, digital inputs with settable sink current profiles
  • All channels isolated from each other and from Raspberry Pi
  • All inputs include transient protection
  • At-a-Glance Input Status LEDs for each channel visible from the front
  • Pluggable terminal blocks for simplified setup and quick changes
  • Up to eight DIGIplates can be stacked together to provide a maximum of 64 channels
  • Onboard programmable LED
 General

  • 100% Tested and Calibrated
  • Dedicated onboard processor
  • Pluggable 3.5mm screw terminal connections
  • Minimum RPi pins required:  15, 16, 22, and 26 while sharing pins 19, 21, and 23.
  • All features accessible via Python command set
  • Supported by Node-RED
  • Supported by PIPLATElogger
  • Compatible with all 40 pin versions of the Raspberry Pi
  • Can be used in combination with all members of the Pi-Plates family
  • Supported by BRIDGEplate
  • Onboard bootloader for firmware updates.
  • Detailed Online Users Guide with Examples
  • Dimensions (with all terminal block plugs attached): 100mm long x 85mm wide x 25mm high
