Pi-SPi-8KO Raspberry Pi Relay Output Module

Pi-SPi-8KO Raspberry Pi Relay Output Interface

Regular price $24.95 Sale

The all new analog input interface for the Raspberry PI is here! The Pi-SPi-8KO has 2 SPDT relays and 6 relay signal outputs. Each signal output can drive a FET or transistor switch.

The design is based on the 74HC595 serial shift register, and has an LED indicator (Active) for each output.

 Node-Red support is now available.

The GPIO expansion port is duplicated on either side of the module, so more modules can be added.

Port Pins Used:    

SPI-MOSI   (GPIO10)
SPI-MISO   (GPIO9) 
SPI-SCK    (GPIO11)
CS_8KO    (GPIO8)

Features:

  • Identical foot print to the RPi 3
  • Separate field power input (24VDC) for relays
  • Each module has its own 3.3VDC LDO regulator operating from the RPi 5VDC bus
  • No loading on the RPi 3.3VDC bus
  • Terminal Blocks for relay contact and output signals
  • LED indicators for power
  • 2 Omron G5LE-14 DC24 Relays (UL,CSA, EN Standards Approved)
  • LED ON Indicators for each Relay and signal output

Pi-SPi-8KO Accessories:

  • Pi-SPi-PS-24VDC Field Power Supply
  • Pi-SPi-CABLE-40x26-2 (40 Pin to 26 Pin x 2")

Sample Software (Python)

Please download the latest Widgetlords libwidgetlords library. The instructions can be found at

Getting Started with PI-SPI Libraries

All of the sample code examples are based on the latest library installation. Please note the code samples all use Python 3.

Basic Python "Write" Relay Output Program:

from time import sleep
from widgetlords.pi_spi import *

init()
relays = Mod8KO()

while True:
    relays.write(0x01)   # Relay 1 ON
    sleep(1)
